Replacing a Line Module by Erasing the Slot Configuration

Use this procedure when you must erase the slot configuration to replace line modules on the ERX routers or on E120 and E320 routers.

For information about replacing the ES2 4G LM or an ES2 10G LM without erasing the slot configuration, see Replacing Line Modules on ERX Routers, the E120 Router, and the E320 Router .

To replace a line module:

1. Copy your slot configuration so you can reconfigure the interfaces after replacing the line module.
2. (Optional) If line module redundancy is configured for the slot, disable redundancy for the slot.

   host1(config)#redundancy lockout 7

3. Disable the slot.

   host1(config)#slot disable 7

4. Remove the current line module and insert the new line module.
5. Issue the slot accept command for the affected slot.

   host1(config)#slot accept 7

   The slot accept command erases the configuration and enables you to reconfigure the new line module.

6. When the replacement line module has come online, reconfigure the interfaces.
7. If you disabled redundancy in Step 2, enable redundancy for the slot when the replacement line module has come online.

   host1(config)#no redundancy lockout 7
