Revert to Alternate Firmware
The Liebert IntelliSlot Unity card has two areas in flash memory for the firmware and the
configuration. One area is currently operating on the card. The other area is considered an alternate.
When a card's firmware is updated, the previous firmware and configuration are moved to the
alternate area. The Liebert IntelliSlot Unity card allows returning to the firmware version and
configuration that are kept in the alternate area.
NOTE
Reverting to an alternate firmware version will not be possible if the currently operating
firmware is the initial version loaded on the Liebert IntelliSlot Unity card. If the initially
loaded firmware is still running on the card, the Alternate Version fields will be blank, and it
will not be possible to revert to an alternate version.
1. Select the Unity Tab at the top of the screen.
2. Select the Support folder, then select the Update Firmware folder.
3. Select the Enable button.
4. Enter the user name and password in the security dialog box that appears; use the administrator
user name and password from the user settings.
5. Click on the Run Alternate button and a confirmation dialog box will appear.
6. Click the OK button on the confirmation dialog box.
NOTE
The card will reboot. After the reboot, the card will be running the previous version of the
firmware and configuration, which had been stored in flash memory. The previous firmware
and configuration will have been moved to the alternate area.
