Issue:
Because the Firmware Upgrade Wizard is the most universal and preferred method of updating, we recommend using the APC Firmware Upgrade Wizard whenever possible. The APC Firmware Upgrade Wizard guides you through the update process and provides a consistent update experience. The Firmware Upgrade Wizard is available in FA279197. Instructions are being provided here for users that are unable use the Firmware Upgrade Wizard and wish to update their Smart-UPS Firmware using command line tools and an APC Network Management Card (NMC). For those who wish to update their Smart-UPS Firmware using the NMC’s web interface, see FA170679.
Product Line:
Smart-UPS models with the prefixes SMT, SMX, SRT, SRTL, XU, and XP with a SmartSlot or Embedded NMC.
Environment:
- Command line terminal emulator and file transfer tools
- Supported UPS model listed above
- UPS Network Management Card 2 (AP9630, AP9630CH, AP9631, AP9631CH, or embedded NMC2) with SUMX application firmware v6.4.0 or higher
- UPS Network Management Card 3 (AP9640, AP9641, AP9643, or embedded NMC3) with SU application firmware 1.0 or higher
- Correct firmware file for the particular UPS available in the table below
Resolution:
Follow the steps below to determine your current NMC type and firmware revision, select the proper UPS firmware image, and update the UPS firmware via the Network Management Card’s Command Line Interface (CLI).
Step 1 - Using an SSH client of your choice, connect to the IP address of the Network Management Card.
Note: If required, Open SSH can be added using Windows Manage Optional Features.
Example of using Windows Command Prompt to connect via SSH:
ssh -c aes256-cbc apc@10.0.0.1
Notes:
- This SSH command is for OpenSSH. The command may differ depending on the SSH tool used.
- The username may be different that the “apc” username used in this example.
Using the web interface of the NMC, navigate to the “SSH Host Key” in the “Console” found in the “Network” section of the “Configuration” menu. Verify and take note of the SSH Key.
Compare the SSH key to the RSA fingerprint displayed in the command line terminal window. To display the fingerprint in the same format as shown in the NMC web interface, the <-o FingerPrintHash=md5> argument can be used. Example:
ssh -c aes256-cbc -o FingerPrintHash=md5 apc@10.0.0.1
Notes:
- Telnet can be used if enabled, but it is not recommended due to lack of encryption, and the examples shown here are just for reference.
- Example of using Windows Command Prompt to connect via Telnet: From a computer that has access to the network on which the NMC is installed, at a command prompt, type telnet and the IP address for the NMC (for example, telnet 10.216.253.128, when the NMC uses the default Telnet port of 23), and press ENTER.
- This example works for command prompt based Telnet clients. The commands may differ for different Telnet clients. If the NMC uses a non-default port number (from 5000 to 32768), you must include a colon or a space, depending on your Telnet client, between the IP address (or DNS name) and the port number. (These are commands for general usage: some clients don’t allow you to specify the port as an argument and some types of Linux might want extra commands).
Enter the user name and password.
Step 2 - Check if you have a Network Management Card 2 running Smart-UPS / Matrix Application, or a Network Management Card 3 running Smart-UPS Application and ensure there are no active alarms reported.
Use the <about> command to display the Network Management Card application module:
Network Management Card 2 installed in a Smart-UPS uses “sumx” Application Module:
Network Management Card 3 installed in a Smart-UPS uses “su” Application Module:
Use the <alarmcount> command to ensure there are no active alarms:
Step 3 - If using Network Management Card 3, go to Step 4.
If using Network Management Card 2: Verify the firmware revision of your Network Management Card. The firmware must be v.6.4.0 or higher, but we recommend you always run the latest available NMC firmware. To update the firmware of your Network Management Card, refer to FA156047.
Use the <about> command to display the Network Management Card firmware version:
Step 4 - IMPORTANT: For Smart-UPS Ultra models with ID 1226 & 1227, the firmware of the Network Management Card must be updated to version 2.5.4.4 or later before updating the UPS firmware. Refer to FA156047 to update the firmware of the Network Management Card.
Note: always download the latest NMC firmware for SUCAN application from se.com:
Step 5 – Identify the correct UPS Firmware file.
- Use the <upsabout> command.
- Identify the "ID" number to select the proper firmware file for your UPS.
- For example, for a UPS with ID 1024 the proper filename will be SRTL1024UPS_xx-x.enc
- Download the appropriate firmware file available in the table below.
The "ID" is a unique identifier for the hardware platform of your UPS. You need to use the "ID" number to make sure to select the correct firmware file. A particular UPS model may have different "ID" numbers depending on when it was manufactured, or its current firmware version. Always check the "ID" number of the UPS before starting the update, and ensure you use a firmware file with the compatible ID. If the incorrect file is used, the update will be refused, and will need to be restarted using the correct firmware file.
Use the table below to determine the correct firmware file for your UPS.
