Replacing IOAs on the E120 Router and the E320 Router

When you configure an IOA in an IOA bay on the E120 and E320 routers, the router stores the configuration in NVS.

When you replace an IOA that supports hot-swapping with the same type of IOA, the line module goes online immediately. When you replace an IOA that does not support hot-swapping with the same type of IOA, the line module reboots.

Before you install an IOA that was previously occupied by another IOA in the E120 or E320 router—for example, an ES2-S1 GE-4 IOA in an IOA bay that previously contained an ES2-S1 OC3-8 STM1 ATM IOA—consider whether the IOA that you are replacing supports hot-swapping. For example:

Replacing SRP Modules and SFMs

If you remove a standby SRP module or an SFM, you must issue the slot erase command to delete the configuration. If you fail to issue the slot erase command, then the E Series router cannot guarantee that the SRP modules were synchronized. In this situation, the E Series router does not properly execute a simple reload command.

To reload the router you must do either of the following:

If you perform one of the following actions, you must reset the configuration of the router to factory default:

You cannot use the slot accept command to force the router to accept the new SRP module.

When you have installed the SRP module in the new location, reset the configuration of the router to factory defaults as follows:

  1. Reload the operating router, then press mb key sequence (case-insensitive) during the countdown.
    host1#reload
  2. Reboot the router with the factory defaults.
    :boot##boot config factory-defaults
  3. Reload the operating router.
    :boot##reload
