Cisco uBR7200 Series and the
Dual-Port HSSI Port Adapter
This chapter provides information on the PA-2H dual-port high-speed serial interface (HSSI) port
adapter and its use on the Cisco uBR7200 series routers.
Installation Overview
The HSSI port adapter is used in the Cisco uBR7200 series routers and can be installed in any of the
available port adapter slots. Figure 6-1 shows an HSSI port adapter installed in port adapter slot 2 of
a Cisco uBR7200 series router.

Depending on your circumstances, you might need to install a new port adapter in a Cisco uBR7200
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 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 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 The Cisco uBR7200 series routers support OIR; therefore, you do not have to power down
the Cisco uBR7200 series router when removing and replacing an HSSI port adapter.
