Replacing Network Modules in Cisco Access Routers with Online Insertion
and Removal Support
Online insertion and removal (OIR) provides uninterrupted network operation, maintains routing
information, and ensures session preservation. The following Cisco access routers support OIR for
similar network modules:

module, install the same model network module in its place. For 1- or 2-slot network modules, you must
install the same network module and interface card combination.
Caution Do not perform OIR on interface cards in 1- or 2-slot network modules. To avoid damage to the interface
card and to the network module, turn off electrical power and disconnect network cables before inserting
an interface card into a network module slot.
OIR procedures require some interaction with Cisco IOS software. For more information on Cisco IOS
software-related tasks, see documents listed in the
Not all Cisco network modules and Cisco interface cards support OIR. Check the hardware
Tip
documentation specific to your network module or interface card to confirm OIR support before starting
OIR procedures.
To replace a network module with OIR support from a Cisco access router, perform the following steps:

(If you are replacing the module) Install a replacement module using the procedures described in the
"Installing Cisco Network Modules in Cisco Access Routers" section on page 2-5
(If you are not replacing the module) Install blank faceplates over the empty slot to ensure proper
airflow. (See the "Installing and Removing Blank Faceplates" section on page
