CAUTION: Swap Bank and Software Reset or Swap Bank After Download and
Reset could disrupt service
Each 9145E 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 9145E. 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
time, the active firmware version, the backup firmware version, and the bootcode.
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
To reset the software, type 1 and press Enter. Reset will be highlighted. Press Enter. The
software will reset. All users will be logged off the system. Software resets will not affect payload
traffic, as long as new software is not being loaded.
8.2 Swap Bank & Reset
The customer 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 9145E 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 9145E resets.
NOTE: All users will be logged off during the 9145E reset. In most cases, payload
traffic through the 9145E will be disrupted for only a few frames while the
FPGA is programmed with the new file.
