Always handle the port adapter by the carrier edges and handle; never touch the port adapter components
or connector pins. (See

Handling a Port Adapter
Online Insertion and Removal
Several platforms support online insertion and removal (OIR) of port adapters; therefore, you do not
have to power down routers when removing and replacing a PA-2FEISL on Cisco 7100 series routers,
Cisco 7200 series routers, or Cisco uBR7200 series routers.
Although the VIP2 and the Catalyst RSM/VIP2 support online insertion and removal,
individual port adapters do not. To replace port adapters, you must first remove the VIP2 or
Catalyst RSM/VIP2 from the chassis and then install or replace port adapters as required. If a blank
port adapter is installed on the VIP2 or Catalyst RSM/VIP2 on which you want to install a new
port adapter, you must first remove the VIP2 or Catalyst RSM/VIP2 from the chassis and then remove
the blank port adapter.
Caution
To prevent system problems, do not remove port adapters from the VIP2 or Catalyst RSM/VIP2
motherboard or attempt to install other port adapters on the motherboard when the system is operating.
To install or replace port adapters, first remove the VIP2 or Catalyst RSM/VIP2 from its interface
processor slot.
It is wise to gracefully shut down the system before removing a port adapter that has active traffic moving
through it. Removing a module while traffic is flowing through the ports can cause system disruption.
Once the module is inserted, the ports can be brought back up.
Note
As you disengage the module from the router or switch, online insertion and removal (OIR)
administratively shuts down all active interfaces in the module.
OIR allows you to install and replace modules while the router is operating; you do not need to notify
the software or shut down the system power, although you should not run traffic through the module you
are removing while it is being removed. OIR is a method that is seamless to end users on the network,
maintains all routing information, and preserves sessions.
