Firmware Maintenance Procedures 7-9
Loading 1757-PLX52, TC-MUX021, or 1757-FIM Boot and
Personality Images
Use the following procedures to update the ROM boot code and
personality images in an existing 1757-PLX52, TC-MUX021 or
1757-FIM module. You must repeat these procedures for all
1757-PLX52, TC-MUX021 and 1757-FIM modules in your system.
Loading Boot Image
1. Click the desired CNB or ENET icon under the desktop tree and
wait for the graphic of the chassis to appear in the detail pane.
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.
TIP The devices with non-compatible versions of
firmware display their firmware versions in red.
Devices with the correct version of firmware display
their firmware version in green. Unknown devices
are displayed in yellow.
