Revert To Alternate Firmware - Emerson Liebert Intellislot Unity Card User Manual

6.2 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 Communications tab at the top of the screen.
2. Select the Support folder, then 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 the Run Alternate button.
A confirmation dialog opens.
6. Click OK on the confirmation dialog.
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.
