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-4E1G 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, you must first remove the Cisco 7304 PCI port adapter carrier card or VIP
from the chassis and then install or replace port adapters as required. If a blank port adapter is installed
on 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 chassis and then
remove the blank port adapter.
To prevent system problems, do not remove port adapters from the Cisco 7304 PCI port adapter carrier
Caution
card or VIP or attempt to install other port adapters on the motherboard when the system is operating.
To install or replace port adapters, first remove the Cisco 7304 PCI port adapter carrier card or VIP from
its interface processor slot.
As you disengage the port adapter from the router or switch, OIR administratively shuts down all active
Note
interfaces in the port adapter.

Handling a Port Adapter
Metal carrier
Printed circuit board
Do not slide a port adapter all the way into the slot until you have connected all required cables.
Trying to do so disrupts normal operation of the router or switch.
If a port adapter lever or other retaining mechanism does not move to the locked position, the port
adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the
slot, reinsert it, and move the port adapter lever or other mechanism to the locked position.
To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and
to ensure that the edge connector at the rear of the port adapter mates with the connection at the rear
of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway
illustrations in the
"Port Adapter Removal and Installation" section on page
