Synchronization and Switchover for Communication Module Series Replacement
If electronic keying is not set to Exact Match, follow these steps to replace communication modules with a new series.
- Make sure the existing modules and the new series modules use the same IP address, network mask, and gateway address.
- Make sure that the RMCT version is compatible with your redundancy firmware.
- Make sure that the redundancy module firmware is at the firmware revision for the specified bundle.
- Go online with the primary controller.
- For each module, verify that the Electronic Keying is set to Compatible Module or Disable Keying.
- Access the RMCT for a redundancy module in either chassis.
- On the Configuration tab, set Auto-synchronization to Never.
- Select Apply.
- On the Synchronization tab, select Disqualify Secondary.
- Make a note of the port configuration of the secondary communication module:
- IP address
- Network mask
- Gateway address
- Disconnect the Ethernet cables from the secondary communication module.
- Turn off power to the secondary chassis.
- Remove the communication module from the secondary chassis.
- Set the switches on the new series communication module to 888, insert the module in the secondary chassis, and apply power to the chassis.
- After the reset is complete, turn power off to the secondary chassis and remove the module from the secondary chassis.
- Set the switches to the same settings as on the module that was removed.
- Reinsert the module into the secondary chassis, reattach the cable, and apply power to the secondary chassis.
- To support bridging across the backplane or USB port, configure the port configuration of the secondary module to match the port configuration of the primary module.
- Update the firmware of the new communication module.
- After the update completes, connect the Ethernet cable to the secondary communication module and wait for communication to resume on the network.
- Repeat steps 10…15.
