Cisco 7200 Series and the 2CT1 Port Adapter
The 2CT1 port adapter is used in the Cisco 7200 series and can be installed in any of the available
port adapter slots. Figure 15 shows a 2CT1 port adapter installed in port adapter slot 1 of a
Cisco 7206.

Installing or Replacing a Port Adapter in Cisco 7200 Series Routers
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 support OIR; therefore, you do not have to power down Cisco 7200
series routers when removing and replacing a 2CT1 port adapter.
