Issue:
Symmetra PX 250/500; What does the EPO (Emergency Power Off) trip
 
Product line:
Symmetra PX 250/500
 
Environment:
All serial numbers
 
Cause:
What occurs when the EPO on a Symmetra PX 250/500 button is engaged?
 
Resolution:
When the EPO is activated, UPS output breaker Q2 and the battery breakers are tripped. The Power Modules (inverter) and if in Static Bypass operation will the UPS turn off

Is there a disposable lid for the 252/32/1 junction box?

No, unfortunately there is nothing available.

Symmetra PX 250/500; AP9635; Flood of RTC Time adjusted values in the logs

Issue:
Flood of RTC Time adjusted values in the logs
 
Product line:
Symmetra PX 250/500 with AP9635
 
Environment:
All Product models, all serial numbers
 
Cause:
When 2 Network Management Card (NMC) are installed in the UPS and set to NTP (Network Time Protocol), they will fight for control of the time to the display and continually send info alerts on RTC Time Adjusted.  In the chart below you will notice in column 5 there are two different numbers 2 & 4, which would indicate that there is 2 NMC in the UPS one in position #2 and the other in position #4.  This is the indicators that 2 NMC are fighting to provide time through NTP

Symmetra PX1-PX2; What happens when PX1, PX2 and 250/500K PX is EPO'd

Issue:
What happens when PX1, PX2 and 250/500K PX is EPO'd
 
Product line:
Symmetra PX
 
Environment:
All models, all serial numbers
 
Cause:
This document describes how the Symmetra PX reacts to the EPO circuit being activated. Emergency Power Off (EPO) is the capability to power down a piece of electronic equipment or an entire installation, in the case of an emergency, from a single point by activating a push button.
 
For 20K, 40K, 80K PX:
If the EPO circuit in the Symmetra PX is activated the System Enable Switch turns to the off position, the DC Breaker in the Main Frame or in the XR Frame (80kw units only) also switches to off. Mains feed CB will be tripped on ISX PDU. There is no power on the output of the XR Battery Frames or on the output of the Symmetra PX UPS.
 
An EPO event is not recorded in the Event Log.
 
For 100K PX:
Only the Battery CBs on XR frames will be tripped. Customer would need to have optional shut trip on Upstream CB to turn off input power to UPS.
 
For 250K/500K PX:
All Battery CBs on battery frames and Q2 will be tripped
 
Resolution:
Reset EPO switch and follow proper procedures to restart UPS
 

Symmetra PX 250/500 Battery to Power Module Ratio

Issue:
Symmetra PX 250/500 Battery to Power Module Ratio

Product line:
Symmetra PX 250/500

Environment:
All Product models, all serial numbers

Cause:
Required battery to power module ratio for a Symmetra PX 250/500

Resolution:

Ratio between numbers of battery shelves and power modules (PM)

Maximum recommended discharge level on the batteries used for Symmetra PX 250/500 is 3CA, where CA means the current (Amps) by which the battery is charged or discharged divided by its Amp-hour (Ah) rating.  The 250kW runtime ratio is 10 PMs to 16 battery shelves resulting in a ratio of 1.6 battery shelf per 1 PM. Need to always round up the number of shelves

Results if ratio is not maintained

In some situations, the Power Modules will attempt to draw power from the batteries and if the ratio is not observed, you will potentially clear fuses in the battery modules and (less likely, but it happened before) burn traces on the battery backplane boards due to the DC inrush current.

 

 

Changing Symmetra PX 250/500 System Time from NMC – Configuring NTP server

Issue:
Changing Symmetra PX 250/500 System Time from NMC – Configuring NTP server

Product line:
Symmetra PX 250/500

Environment:
All Product models, all serial numbers

Cause:
Time not updating on UPS when changed on NMC

Resolution:
Making changes on the NMC web interface will also make changes on the ups, but the NMC must first be configured for Read/Write in the user configuration settings on the UPS.  Once this is configured making changes on the NMC will update the display on UPS.

When changing NMC configuration to update Time using NTP, you need to pay attention to the update Interval.  It can be set from 1 to 8760 hours(1 year).  Make sure this is configured as needed.  If time is not immediately updating, click the UPDATE Now box and click apply.  You may need to refresh screen on UPS a couple times to see the change.

Video: How do I upgrade the firmware on an APC Network Management Card (NMC) or NMC embedded device (Rack PDU, etc)?

Issue
  • You wish to upgrade your Network Management Card's (NMC) firmware or have been instructed to.
  • You have a device such as a Rack PDU, AV unit, or environmental monitoring unit with an embedded NMC that you wish to upgrade.
  • You had a problem with a previous upgrade attempt and need the instructions in order to correct it.
  • Your device came pre-loaded with the wrong application and you need to load the correct application.

Product Line
  • Web/SNMP Card - AP9606
    Devices with an embedded Web/SNMP Card include (but are not limited to): Environmental Monitoring Unit 1 (AP9312TH).
     
  • Network Management Card 1 - AP9617, AP9618, AP9619
    Devices with an embedded Network Management Card 1 include (but are not limited to): Metered/Switched Rack PDUs (AP78XX, AP79XX), Rack Automatic Transfer Switches (AP77XX), Environmental Monitoring Units (AP9320, AP9340, Netbotz 200).

Environment
  • All serial numbers
  • All firmware versions (unless otherwise noted)

Cause

Users may wish to upgrade their firmware to take advantage of enhancements, bug fixes, or new features. Also, sometimes a firmware upgrade can be interrupted or fail and these instructions can be followed to remedy the problem.

Typically, these upgrades do not require the device the Network Management Card is installed in to be powered down or cause unnecessary downtime.

Lastly, downgrades are not typically recommended but the manual methods can also be used to do those in certain circumstances.

Note: For users upgrading (or downgrading) their Network Management Card 2 device from v5.X.X to v6.X.X, please review knowledge base FA167693 to understand several important considerations.


Resolution

When upgrading the firmware on your Network Management Card (NMC), you will need to determine which files pertain to your application. Begin by determining what model of NMC you have.
 
  • AP9606 - Web SNMP Management Card
  • AP9617, AP9618, AP9619 - Network Management Card
  • AP9630, AP9631, AP9635 - Network Management Card 2
  • AP9603, AP9605 - Token Ring Adapter, SNMP adapter - no updates available

These instructions can also be used in devices that have embedded (mini) versions of the above Network Management Cards.


If you are interested in upgrading multiple devices at a time, refer to knowledge base FA156117.
 

*If you have an AP9635 installed in a Symmetra PX 250/500, you have a Network Management Card 2 but MUST contact APC Technical Support in order to obtain the correct firmware and special instructions.
Next, determine which device you have the Web SNMP/Network Management Card installed in.

For example, if you have the Network Management Card installed in a UPS, you need to determine which UPS you have. APC offers several different UPS families. Some of these families include:
  • Smart UPS
  • Matrix
  • Symmetra 1 phase (Symmetra, Symmetra Rackmount, Symmetra LX)
  • Symmetra 3 phase (Symmetra PX)
  • Symmetra PX 250/500kVA
  • Silcon*

*Not supported on the NMC2 platform.

Select the correct UPS or device type. Next, go to the Firmware Upgrades - Network Management Card section on the software downloads page. A link to the software downloads page is below:

https://www.apc.com/tools/download/
For example, if you have a Smart UPS 750 (SUA750), then you will choose:

Network Management Card v3.X.X firmware executable for Smart UPS and Matrix w/AP9617/8/9 installed
or
Network Management Card v5.X.X firmware executable for Smart UPS w/AP9630/31 installed

Network Management Cards with the SKU of AP9617, AP9618, or AP9619 use firmware 3.X and Network Management Card 2 units with the SKU of AP9630, AP9631 use version 5.X or 6.X firmware. The correct firmware for each platform must be used and they are not interchangeable.
 
  • Click on the download link on the right hand side of the page. Proceed through the menus and download the firmware executable. Once you have the firmware downloaded, then you can proceed with the upgrade.
    • Please note, AP9606 has been discontinued for some time and firmware for this device is located only on the APC public FTP site here. You will need to download the AOS file and then the appropriate application for your type of device.
There are different ways that you can upload the firmware for each device. Please choose a method that works best for you. 


Note: For users upgrading (or downgrading) their Network Management Card 2 device from v5.X.X to v6.X.X, please review knowledge base FA167693 to understand several important considerations prior to beginning any of these steps.

 


Universal Serial Bus (USB) 1.1 - Network Management Card 2*devices with USB


*If you have an AP9635 installed in a Symmetra PX 250/500, you have a Network Management Card 2 but MUST contact APC Technical Support in order to obtain the correct firmware and special instructions, PRIOR to following the steps below. Failure to do so may result in unexpected operation of your AP9635 Network Management Card 2.

 
Note: Some USB flash drives are not compatible with the NMC2 devices. Secondly, the flash drive's file system must be FAT, FAT16, or FAT32. (NTFS will not work).

1. Obtain the latest firmware files from apc.com and extract them to a folder. Please note, USB may not allow for a firmware downgrade. You must use a manual method to accomplish a downgrade.

2. Create a folder on your USB flash drive called apcfirm .

3. From the latest firmware files that you downloaded, add to the apcfirm folder the binary files for the firmware modules that you would like to upgrade. Some examples of the binary files for the three firmware modules follow:
 
Firmware Module Binary File
 APC Boot Monitor  apc_hw05_bootmon_108.bin
 APC Operating System (AOS)  apc_hw05_aos_621.bin
 Application Module  apc_hw05_sumx_621.bin
 Language Pack*  sumx_620_frFrdeDeruRuitItesEs.lpk
 *Optional language pack upgrades/changes are supported via USB if the device your upgrading already has BootMonitor v1.0.8 or higher (BootMonitor performs the upgrading function)
Note: Not all NMC2 applications support language packs.
 
4. Use a text editor such as Microsoft Notepad to create a file called upload.rcf. (Ensure that file extensions are visible so that your file does not get named upload.rcf.txt. In Windows, this option can be edited in Folder Options->View->Hide extensions for known file types within Control Panel. Make sure that option is unselected.) Add to the file a line for each firmware module that you want to upgrade as shown below (replace "XXX" with the version of firmware you will be upgrading to):
 
BM=apc_hw05_bootmon_XXX.bin
AOS=apc_hw05_aos_XXX.bin
APP=apc_hw05_sumx_XXX.bin
LANG=sumx_XXX_frFrdeDeruRuitItesEs.lpk

 
5. Add the upload.rcf file to the apcfirm folder on the flash drive.

6. Insert the flash drive into the USB port on the NMC2.

7. Press and release the pinhole Reset button on the NMC2 for the USB upgrade process to begin. (This will only reboot the management interface of the NMC2 and not reboot your device/load.) The NMC2 status LED, located on the RJ-45 Ethernet jack, will begin to blink amber during this procedure and rotate through a few color flashing patterns while transferring the different files.  Note: If you have an AP9631 or AP9635 removable NMC2 UPS SmartSlot card, you can also remove and re-insert the card into the UPS SmartSlot, effectively rebooting the NMC2 and beginning the USB upgrade process this way.

8. Wait for two to five minutes for the upgrade to complete. Remove the flash drive from the USB port and check your firmware version. On a Rack PDU specifically, the LCD display will show the firmware version for three seconds and then will resume normal operation, at which time you can also remove the flash drive.



Firmware executable - Network Management Card 1 and 2*
If you have a Windows computer, you can use the firmware executable to upgrade the firmware.

If you have any other type of computer, then you will need to manually upload each firmware file to the Web SNMP/Network Management Card. Go to the XMODEM or Manual sections below for additional instructions.

Note: For any firmware downgrades, which are not typically recommended, you will need to choose a new method. The Wizard will block any downgrades. Unfortunately, loading applications for different devices may also have encounter this block if AOS versions are not the same.


*If you have an AP9635 installed in a Symmetra PX 250/500, you have a Network Management Card 2 but MUST contact APC Technical Support in order to obtain the correct firmware and special instructions, PRIOR to following the steps below. Failure to do so may result in unexpected operation of your AP9635 Network Management Card 2.
 
  1. Click on the firmware executable once the download is complete. The executable will proceed to unzip firmware files and extract them. You can specify the location where you want the firmware to download to.
  2. Once the firmware has been saved, the executable will prompt you for the IP address of the Web SNMP/Network Management Card that you want to upgrade.
  3. Once you enter the IP address, click enter.
  4. You will be prompted for a username and password.
    • NMC1 - This must be the Administrator user account on NMC1. By default, the Administrator username and password is apc. Press enter.
    • NMC2 - This must be the Super User Account or an Administrator account. By default, the Super User username and password is apc. Press enter.
  5. If using the NMC1 executable, You will then be prompted to either 1) Continue with upgrade 2) Re-enter Parameters 3) Quit. Choose option 1 then enter. *In NMC1 Upgrade Utility v1.2 or higher, a username or password longer than 11 characters will be truncated. Thus, you will need to change the password to 11 characters or less or choose another firmware upgrade method. Reference the picture below on how to check your NMC Upgrade tool version.

 
  1. If using the NMC2 firmware upgrade utility/wizard, seen below, you will be prompted to enter the IP address and username and password. You can enter those and press Upgrade Now.
 
 
  1. The firmware executable will then begin the upgrade process. This process may take as long as 5-7 minutes to finish. Once finished, close the executable.
  2. Verify that the firmware upgrade was successful.
    • NMC1 - Log into the web interface and go to Administration Tab->General->About menu. The updated firmware should be listed on this page. Alternatively, verify via Telnet, SSH, or local console connection on the main page after log in.
    • NMC2 - Log into the web interface and go to About->Network menu. The updated firmware should be listed on this page. Alternatively, verify via Telnet, SSH, or local console connection on the main page after log in.



XMODEM - Web/SNMP Card (AP9606)
The Local Control Console allows you to use TFTP, FTP, and XMODEM.

1. Use the Settings option to define the file name.

2. Select TFTP, FTP, or XMODEM from the menu and follow the onscreen instructions.


XMODEM - Network Management Card 1 (AP9617, AP9618, AP9619)

***For AP9617/18/19 cards that have AOS 1.2.0 firmware and below, you will need to first upgrade to AOS 2.0.2 before upgrading to the latest firmware. AOS 2.0.2 should be included as part of the firmware executable located on the firmware download page.***

1. Connect the Management Card to an available serial port on the host computer with the supplied cable (part number 940-0024).

2. If PowerChute is running, then stop that service.

3. Open a terminal session. Configure the terminal session to 2400bps, no parity, 8 data bits, 1 stop bit, and no flow control. If you are using HyperTerminal, select Call->Disconnect and then Call->Connect to apply the changes to the serial port. Please note that certain terminal emulation programs, such as PuTTy, do not support the XMODEM protocol.

4. Press the <Enter> key several times. You should see a User Name prompt. If you do not see the prompt, make sure that you have the proper cable and that the communication settings are correct.

5. Enter the Administrator account User Name and Password. The default for both is apc. If you have changed the Administrator User Name and Password, use the new settings to log in. The main Control Console menu will appear.

6. Start an XMODEM transfer.

7. Select option 3 - System.

8. Select option 4 - Tools

9. Select option 6 - File Transfer.

10. Select option 1 - XMODEM.

11. Enter "YES" at the prompt to continue with the transfer.

12. Select the appropriate baud rate. The higher the baud rate, the faster the firmware upgrade.

13. You then need to change the terminal program's baud rate to match the one you selected in step 12. If you are using HyperTerminal select Call ->Disconnect and go to File->Properties->Configure and choose the correct speed. Accept the changes and then to reestablish the connection choose the Call menu->Connect to apply changes made to the serial port. Press <ENTER> to  continue.

14. From the terminal program's Transfer menu, select the appropriate firmware .bin firmware file to transfer via XMODEM-CRC. To do this within HyperTerminal, go to the Transfer Menu->Send File. On the dialog box that pops up, browse the computer for the appropriate firmware .bin file. Once you do that, ensure the selected protocol is XMODEM and then press Send to begin the file transfer. For AP9617/18/19 based devices, the AOS should be transferred first and then the procedure should be repeated for the application file.

15. After the XMODEM file transfer is complete, set the baud rate back to 2400 within the terminal program's settings. The Management Card will automatically reboot itself . (Please note that a reboot of the NMC does not affect the output of the device.)

 
XMODEM - Network Management Card 2 (AP9630, AP9631, AP9635)*


*If you have an AP9635 installed in a Symmetra PX 250/500, you have a Network Management Card 2 but MUST contact APC Technical Support in order to obtain the correct firmware and special instructions, PRIOR to following the steps below. Failure to do so may result in unexpected operation of your AP9635 Network Management Card 2.
If you wish to downgrade from v6.X.X to v5.1.X firmware on NMC2, please make sure you review knowledge base article 167693 prior.

Manual (via FTP) - Web/SNMP Card (AP9606) & Network Management Card 1 and 2*
*If you have an AP9635 installed in a Symmetra PX 250/500, you have a Network Management Card 2 but MUST contact APC Technical Support in order to obtain the correct firmware and special instructions, PRIOR to following the steps below. Failure to do so may result in unexpected operation of your AP9635 Network Management Card 2.


***For AP9617/18/19 cards that have AOS 1.2.0 firmware and below, you will need to first upgrade to AOS 2.0.2 before upgrading to the latest firmware. AOS 2.0.2 should be included as part of the firmware executable located on the firmware download page.***

If you wish to downgrade from v6.0.X to v5.1.X firmware on NMC2 devices, please make sure you review knowledge base article 167693 prior.


1. To perform a firmware flash with this method the Management Card must have been previously configured with a System IP, Subnet Mask, and Default Gateway and attached to the network. In addition, FTP Server must be enabled.

2. Open an MS-DOS command prompt window on a PC which is connected to the network. Change to the directory which contains the firmware upgrade files. Some example commands which need to be entered are shown in bold in order to change directories. Please note, this is just an example. You may need to enter a full path to a directory which requires different syntax.
C:\> cd apc
C:\apc>

 
3. Open an FTP client session.

C:\apc> ftp 192.168.1.100 (192.168.1.100 being the IP address of the web card)

 
4. Log in.
  • NMC1 - This must be the Administrator user account on NMC1. By default, the Administrator username and password is apc. Press enter.
  • NMC2 - This must be the Super User Account or an Administrator account. By default, the Super User username and password is apc. Press enter.

7. Wait about 20 - 30 seconds.

8. Repeat Steps 3 - 8 again for the application module (sumx for Smart UPS/Matrix, sy for Symmetra, etc). In Step 6, substitute the sumx module file name, in place of the AOS module file name. Or the sy prefix for the Symmetra.
 
*To upgrade multiple Management Cards using an FTP client or using SCP, write a script which automatically performs the procedure.


Note: If using MacOSX, the full filepath of the destination folder will need to be included in the "put" command. An example command would read:
ftp> put /Users/Admin/Downloads/aosXXX.bin /aosXXX.bin

 
Manual (via Secure CoPy) - Network Management Card 1 and 2*
*If you have an AP9635 installed in a Symmetra PX 250/500, you have a Network Management Card 2 but MUST contact APC Technical Support in order to obtain the correct firmware and special instructions, PRIOR to following the steps below. Failure to do so may result in unexpected operation of your AP9635 Network Management Card 2.

If you wish to downgrade from v6.X.X to v5.1.X firmware on NMC2, please make sure you review knowledge base article 167693 prior.



*For NMC1, SCP is supported and available as of AOS 2.0.0. If you have version 1.X.X, please upgrade to at least 2.X.X or the latest firmware version.
1. Identify and locate the firmware modules described in the preceding instructions for FTP.

2. Use an SCP command line to transfer the AOS firmware module to the Management Card. The following example uses xxx to represent the version number of the AOS module:
 
scp apc_hw05_aos_xxx.bin apc@158.205.6.185:apc_hw05_aos_xxx.bin
 
3. Use a similar SCP command line, with the name of the application module, to transfer the application firmware module to the Management Card.
 
 
*To upgrade multiple Management Cards using an FTP client or using SCP, write a script which automatically performs the procedure. Alternatively, you can use APC's INI utility which is downloadable and explained in knowledge base FA156117.

Note: Never remove a Management Card before it completes the reboot cycle. Doing so will damage the Management Card. The reboot cycle is complete when the status LED turns off and after 20 seconds turns solid green or slowly flashing amber.

    • Symmetra PX 250/500
 
  • UPS Network Management Card 2
    • AP9635/35CH

Environment:
  • All installation scenarios

Cause:

The AP9635/AP9635CH Network Management Card 2 (NMC2) is restricted for use with the Symmetra PX 250/500 UPS and other select UPS models. Additionally, before upgrading the firmware for the Management Card when installed in a, you must make sure that the firmware upgrade is compatible with the firmware level that is running on the UPS system (its MIM, PM, etc) . For example, as described in the chart below, a Management Card running v5.0.0 firmware cannot support a UPS with system firmware 4.1.x.x unless the Management Card is upgraded to the SYPX APP v5.0.1 firmware. To obtain the firmware upgrade files for the Management Card, you must contact Technical Support.


Alternatively, the UPS System firmware can be updated to support a Management Card with newer firmware.

Note: The UPS system firmware upgrade can only be performed by a Field Service Engineer.


Resolution:

Review the chart below to make sure the Management Card is running firmware that is compatible with the UPS. To view the UPS System firmware and NMC APP firmware versions from the UPS touchscreen display, press the Firmware Overview button in the System Information menu. The APP firmware version of the Management Card is also displayed in its Web interface, under the Administration->General->About menu.

UPDATED MARCH-2016: Unable to access my APC Network Management Card (NMC) enabled device via HTTPS (SSL/TLS)


Issue

The user is unable to access their APC Network Management Card (NMC) products via HTTPS (SSL/TLS) secured web access.

There are two parts to this issue, both of which occur when the user has their Network Management Card product configured for SSL (HTTPS).
  1.  Companies such as Microsoft, Mozilla, and Google are disabling SSLv3.0 in their browser products due to numerous security vulnerabilities that exist. One such vulnerability is POODLE (https://www.openssl.org/~bodo/ssl-poodle.pdf).  TLSv1.0, at a minimum, is the advised protocol.
 
  1. TLS does not work on the current NMC products.  Therefore, the NMC will fall back to SSLv3.0 and as such, be vulnerable to POODLE.

Examples:
 
An example of this problem, shown via Firefox, is below. A NetBotz Rack Monitor 200 (SKU# NBRK0201) is configured for HTTPS. The user has Firefox v34.0 installed. The user opens their web browser and types the IP address into address bar.  The user is presented with the following error message:
 

Another example of this problem, via Internet Explorer, is below. A NetBotz Rack Monitor 200 (SKU# NBRK0201) is configured for HTTPS.  The user has Internet Explorer v11.0 installed. The user opens their web browser and types the IP address into address bar.  The user is presented with the following error message:
 

Another example of this problem, via Chrome, is below. An AP9631 Network Management Card is configured for HTTPS. The user has Chrome v39 installed. The user opens their web browser and types the IP address into the address bar. The user is presented with the following error message:
 


Browser error messages may include: ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION, ssl_error_no_cypher_overlap


Note: If you've received mozilla_pkix_error_inadequate_key_size, sec_error_invalid_key, or anything referring to invalid key size/length, please consider reviewing knowledge base article ID FA162031 as this may be due to a separate issue entirely or an additional issue.

Environment

Any customer who uses any one of the products mentioned previously and:
  • Configures their product for SSL (HTTPS).
  • Uses a web browser version that does not allow for web access via SSLv3.0.
Note: HTTP users are not affected. Meaning, if you have not enabled HTTPS (SSL), web browsing will work normally.


Cause

Companies such as Microsoft, Mozilla, and Google are disabling SSLv3.0 in their browser products due to numerous security vulnerabilities that exist. One such example is POODLE (https://www.openssl.org/~bodo/ssl-poodle.pdf). TLSv1.0, at a minimum, is the advised protocol.

Current NMC products have an inability to properly utilize TLS extensions recently released in several modern browsers. With this inability, the NMC device is unable to connect to the browser via TLS. While future versions of the NMC1 devices will not update the underlying cryptology engine, NMC2 devices will be updated to work with current TLS specification and and operate properly with modern browsers.


Resolution

A customer can avoid this problem either by utilizing other access methods on the Network Management Card or they can modify their web browser to allow SSLv3.0 usage (at their own discretion). Other access methods for the Network Management Card are as follows:
  • Local console
  • Web (HTTP)
  • Telnet/SSH
  • SNMPv1/v3

Modifying a web browser to allow SSLv3.0 usage should be addressed by the user’s network security team or facility manager. Schneider Electric will not provide users with instructions on modifying web browser settings. Some users may be prohibited from enabling SSLv3.0 through their web browser.

Any of the following NMC1 products do not currently have any firm future firmware update plans to address this or any future vulnerabilities:
  • AP9921X Battery Management System
  • AP7750, AP7722, AP7701 Rack Automatic Transfer Switches
  • AP9340, AP9320 Environmental Monitoring Units
  • S20BLK A/V Power Conditioner & Battery Backup
  • PDPMXXX Modular Power Distribution
  • FM35XX Network Air, ACDA901, Stulz C7000

pxhid AP9361 Rack Access PX-HID AOS v3.9.0 and higher Yes
 

Note: Certain browsers may also require setting changes to allow TLS 1.0 or TLS 1.0 fallback too, such as Firefox v37+. Schneider Electric will not provide step by step instructions for modfying web browser settings for liability reasons but if you're comfortable modifying settings at your own risk, security.tls.version.fallback-limit within Firefox will likely need to be changed from a default value of 3 (forcing TLS 1.2) to a value of 1 to allow fallback to TLS 1.0. This setting also sometimes resets itself between Firefox browser upgrades. Newer Chrome versions may require --ssl-version-fallback-min=tls1 to be appended to the program shortcut.


A fix to address this problem in the Network Management Card 2 (NMC2) and NMC2 enabled devices has been implemented. The release date will be determined on a product by product basis. See below for available updates for NMC2 firmware applications. These updates provide TLS 1.0, TLS 1.1 and TLS 1.2 functionality.
