Perform a Direct Module Replacement in the Secondary Chassis
A direct module replacement in the secondary chassis requires the new module to have the same catalog number, series, and firmware.
IMPORTANT:
When you replace communication modules, make sure that the rotary switches and port configuration match the existing modules.
To perform a direct module replacement in the secondary chassis, follow these steps.
- Access the RMCT for the redundancy module in either chassis.
- On the Configuration tab, set Auto-Synchronization to Never.

- On the Synchronization tab, select Disqualify Secondary.

- With the redundancy module fiber cables still connected, remove the module from the secondary chassis.
- Insert the replacement module in the same slot in the secondary chassis.
- If applicable, update the module firmware by usingControlFLASH Plus®software.
- On the Configuration tab of the RMCT, set Auto-synchronization to the original setting.
- On the Synchronization tab, select Synchronize Secondary.
