7-14 Firmware Maintenance Procedures
Updating Firmware in CNB, ENET, IOM, SRM, PIM
or ControlNet Adapter
The procedure for updating the firmware in other modules is basically the
same as the one used for updating a 1784-PCIC card.
1. Launch the NTOOLS utility (ntools -c -u or ntools -e -u).
refer to Starting Network Tools Application on page 7-8.
2. Click the desired CNB or ENET icon.
3. Select the module to be updated in the chassis graphic.
4. Click Firmware and click Yes to acknowledge the warning.
5. Select the path to the correct .nvs file.
See Table 7.A on page 7-5.
ATTENTION
!
Redundant Chassis Firmware Upgrade
Precautions
When updating modules in an RCP, you MUST turn OFF
power to the Secondary Chassis in the RCP, so you can
update the firmware in the modules in the powered
controller chassis while it is in a Primary with no partner
state. Failure to remove power from the Secondary Chassis
may result in an unrecoverable loss of the RM.
Once the modules are 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 modules in the RCP. This avoids possible confusion
caused by the logical change in Network Addresses in
response to a controller switchover.
Never cancel an RM firmware upgrade in process.
Interruption of an RM firmware upgrade during the boot
code load may result in an RM that will not power up
properly and that cannot be recovered by power cycling the
unit.
