Firmware Maintenance Procedures 7-13
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 7-7.
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.
ATTENTION
!
Whenever you are updating modules in an RCP, we
recommend you turn OFF power to one of the
controller 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.
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.
When updating RMs, the operator MUST turn OFF
power to the Secondary Chassis. Failure to remove
power from the Secondary Chassis may result in an
unrecoverable loss of the RM.
IMPORTANT
The 1756-ENET module must be in Slot 0 to update
the firmware.
