Chapter 3 Installing the Cisco ASR 903 Router
Interface Module Installation
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.
