Cisco uBR7200 Series and the PA-E3

This chapter provides information on the PA-E3 serial port adapter and its use in Cisco uBR7200

series universal broadband routers. This chapter includes the following sections:

• Overview, page 6-1

• Removing a Port Adapter, page 6-2

• Installing a Port Adapter, page 6-4

Overview

The PA-E3 can be installed in any of the available port adapter slots in Cisco uBR7200 series routers.

Figure 6-1 shows a PA-E3 installed in port adapter slot 2 of a Cisco uBR7200 series router.

Depending on the circumstances, you might need to install a new port adapter or replace a failed port

adapter in a Cisco uBR7200 series router. In either case, no tools are necessary; all port adapters

available for the Cisco uBR7200 series routers connect directly to the router midplane and are locked

into position by a port adapter retention clip (Cisco uBR7246) or lever (Cisco uBR7223). When

removing and replacing a port adapter, you 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.
