Installing or Replacing a Port Adapter in Cisco 7200 Series Routers
This section provides the standard procedures for installing or replacing port adapters in a
Cisco 7200 series router.
Depending on your circumstances, you might need to install a new port adapter in a Cisco 7200
series router or replace a failed port adapter in the field. In either case no tools are necessary; all port
adapters available for the Cisco 7200 series connect directly to the router midplane and are locked
into position by a port adapter lever. When removing and replacing a port adapter, you will need an
antistatic mat onto which you can place a removed port adapter and an antistatic container into which
you can place a failed port adapter for shipment back to the factory.
Note
Cisco 7200 series routers when removing and replacing a port adapter.
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router
to conform to EMI emissions requirements and to allow proper air flow across the port adapters. If
you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port
adapter.
