Handling Port Adapters
Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge
(ESD) damage.
Always handle the port adapter by the carrier edges and handle; never touch the port adapter components

or connector pins. (See

Online Insertion and Removal
The Cisco 7200 VXR platform supports online insertion and removal (OIR) of port adapters; therefore,
you do not have to power down routers when removing and replacing a PA-MC-T3-EC in Cisco 7200
VXR routers.
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.
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
After removing a PA-MC-T3-EC, wait 3 minutes before reinstalling or reinserting a PA-MC-T3-EC.
Online insertion and removal (OIR) is not supported on the Port Adapter Jacket Card. OIR is supported
Note
on the port adapter. You must have the chassis powered off to install or remove the Port Adapter Jacket
Card.
