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-2FE in the Cisco 7100 series routers,
Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router,
Cisco 7301 router, or Cisco 7401ASR router.
Although the Cisco 7304 PCI port adapter carrier card and VIP support OIR, individual port adapters do
not. To replace port adapters in the Cisco 7304 router or Cisco 7500 series routers, you must first remove
the Cisco 7304 PCI port adapter carrier card or VIP from the router and then install or replace
port adapters as required. If a blank port adapter is installed in the Cisco 7304 PCI port adapter carrier
card or VIP on which you want to install a new port adapter, you must first remove the Cisco 7304 PCI
port adapter carrier card or VIP from the router and then remove the blank port adapter.
Caution To prevent system problems, do not remove port adapters from the Cisco 7304 PCI port adapter carrier
card or Cisco 7500 VIP motherboard or attempt to install other port adapters when the system is
operating.
OIR allows you to install and replace port adapters and service adapters (carrier cards and VIPs) 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 port adapter 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.
It is wise to gracefully shut down the system before removing a port adapter that has active traffic moving
through it. Removing a port adapter while traffic is flowing through the ports can cause system
disruption. Once the port adapter is inserted, the ports can be brought back up.
Note As you disengage the port adapter from the router or switch, OIR administratively shuts down all active
interfaces in the port adapter.
The following is a functional description of OIR for background information only; for specific
procedures for installing and replacing a PA-2FE in a supported platform, refer to the “Port Adapter
Removal and Installation” section on page 3-4.
