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.
  1. Access the RMCT for the redundancy module in either chassis.
  2. On the Configuration tab, set Auto-Synchronization to Never.

  5. Insert the replacement module in the same slot in the secondary chassis.
  6. If applicable, update the module firmware by using

     software.
  7. On the Configuration tab of the RMCT, set Auto-synchronization to the original setting.
