6-28 July 2004 Wide Bank 28 DS3 - Release 2.4
Figure 6-6 Re-Programming the FLASH on Controller A
NOTE: If you are using a Telnet session, it will be closed here. Re-establish the Telnet
session on Controller B to continue.
The Wide Bank initiates a switch of Controllers, then executes the commands necessary to cause
the firmware just downloaded to RAM to be programmed into the FLASH on the board that used
to be active (Controller card A) (see Figure 6-6). During this programming, the traffic is carried by
the secondary Controller card (B), which is now active. After the download is complete
(approximately one minute), press Enter key to initiate a log-in to Controller card B.
