Installing the Cisco ASR 903 Router
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 problem in the bus and should be removed.
To avoid erroneous failure messages, note the current configuration of all interfaces before you remove
Caution
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.
Swapping of Interface Modules
The Ethernet interface modules support swapping on the Cisco A900-RSP2A module.
• 8-port Gigabit Ethernet SFP Interface Module (8X1GE)
• 8-port Gigabit Ethernet RJ45 (Copper) Interface Module (8X1GE)
• 1-port 10 Gigabit Ethernet XFP Interface Module (1X10GE)
• SFP Combo IM—8-port Gigabit Ethernet (8X1GE) + 1-port 10 Gigabit Ethernet (1X10GE)
• Copper Combo IM—8-port Gigabit Ethernet (8X1GE) + 1-port 10 Gigabit Ethernet Interface
Module(1X10GE)
• 2-port 10 Gigabit Ethernet Interface Module(2X10GE)
Use the hw-module subslot default command before performing a swap of the modules. to default the
interfaces on the interface module.
The hw-module subslot default command is not supported on the TDM and OC-3 interface modules.
