CAUTION: Swap Bank and Software Reset or Swap Bank After Download and Reset could
disrupt service
Each 9145EMP has two flash memory banks that store software. The Active Flash Memory bank
holds the software that is currently in use. The Inactive Flash Memory bank holds the new
software from a download, or the older version of software from a previous upgrade. Software
can be downloaded into the Inactive Flash Memory bank without disrupting the normal operation
of the 9145EMP. Downloading software into the Inactive Memory bank is a background operation
and will not disrupt services.
From the Main Menu, select Software Upgrade (7) and press Enter. The Software Upgrade
screen (Figure 8-1) opens. The Software Upgrade screen displays the time since the last restart,
the active firmware version, the backup firmware version, and the bootcode version.
The Software Upgrade screen provides functions to reset the software, swap active flash
memory banks, swap flash memory banks after a download and reset, and get a new file with
TFTP.
8.1 Software Reset
1. To reset the software, type 1 and press Enter. Reset will be highlighted.
2. Press Enter. The software resets. All users will be logged off the system.
Software resets do not affect payload traffic, as long as new software is not being loaded.
8.2 Swap Bank & Reset
You can elect to exchange the current software being executed with the software stored in the
inactive flash memory bank. This process will swap flash memory banks (active > inactive,
inactive > active) and reset the 9145EMP to activate the setting. The software in the inactive
flash memory bank will become active and the active flash memory bank will become inactive
when the 9145EMP resets.
