When you remove or insert a redundant module while the router is powered on and running, the router does
the following:
1. Determines if there is sufficient power for the module.
2. Scans the backplane for configuration changes.
3. Initializes the newly inserted module. In addition, the system notes any removed modules and places those
modules in the administratively shutdown state.
4. Places any previously configured interfaces on the module back to the state they were in when they were
removed.
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
• If the tests pass, the router is operating normally.
• If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.
• If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a
Caution To avoid erroneous failure messages, note the current configuration of all interfaces before you remove or
replace an interface module, and allow at least 2 minutes for the system to reinitialize after a module has been
removed or replaced. This time is recommended in order to allow for synchronization between components
within the interface module and for synchronization with the standby RSP.
