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
Replacing a Line Module Without Erasing the Slot Configuration
Use this procedure when you are replacing an ES2 4G LM with an ES2 10G LM or an
ES2 10G ADV LM, or vice-versa. Both line modules must already be paired with an
ES2-S1 GE-8 IOA or the ES2-S1 Redund IOA.
You can also use this procedure when you are replacing ES2 10G LM with ES2 10G
ADV LM, or vice-versa. In this case, both the line modules must be paired with any
one of the following IOAs:
■ ES2-S2 10GE PR IOA
■ ES2-S1 10GE PR IOA
■ ES2-S1 REDUND IOA
You can replace a single line module or all of the line modules in a redundancy group
using this procedure.
NOTE: In some cases, the ES2 4G LM and ES2 10G LM support different system
maximums and protocols. Before you replace an ES2 4G LM with an ES2 10G LM or
ES2 10G ADV LM, make sure that:
■ The ES2 10G LM or ES2 10G ADV LM supports the features already configured
on the slot for the ES2 4G LM.
■ The ES2 10G LM or ES2 10G ADV LM can support the existing system maximums
configured on the ES2 4G LM.
If you have a configuration on the ES2 4G LM that is not supported on the ES2 10G
LM or ES2 10G ADV LM, you must erase the configuration before replacing the line
module. For more information, see “Replacing a Line Module by Erasing the Slot
Configuration” on page 365 .
To replace a line module without erasing the slot configuration:
1. (Optional) If line module redundancy is configured for the slot, disable
redundancy.
host1(config)#redundancy lockout 1
2. Disable the slot.
