Loading 1757-PLX52 and TC-MUX021 Boot and Personality Images
Use the following procedures to update the ROM boot code and
personality images in an existing 1757-PLX52 or TC-MUX021 module.
You must repeat these procedures for all 1757-PLX52 and TC-MUX021
modules in your system.

ATTENTION
!
Be certain that your process is off control before you
begin any upgrade procedure. This means the
1757-PLX52 should be in the Idle state.
ATTENTION
!
;
Whenever you update 1757-PLX52 modules in a
Redundant Chassis Pair (RCP), we recommend you
turn OFF power to one of the controller chassis in the
RCP, so you can update the firmware in the
1757-PLX52 in the powered controller chassis while it
is in a Primary with no partner state.
Once the 1757-PLX52 module is updated in the
powered chassis, turn OFF power to this chassis and
turn ON power to the other controller chassis to repeat
the firmware update for the other 1757-PLX52 in the
RCP. This avoids possible confusion caused by the
logical change in Network Addresses in response to a
controller switchover.
