Overview

This chapter provides physical and functional overviews of the PA-2H dual-port high-speed serial

interface (HSSI) port adapter. The chapter contains the following sections:

Port Adapter Overview

The PA-2H dual-port HSSI port adapter provides two high-speed serial interfaces. (See Figure 1-1.)

The interfaces on PA-2H are considered to be data terminal equipment (DTE) devices. (Port adapters

have a handle attached, but this handle is occasionally not shown in ﬁgures in this publication to

allow a full view of detail on the port adapter faceplate.)

Figure 1-1 PA-2H Port Adapter (Faceplate View)

HSSI network interfaces reside on modular port adapters, which provide a direct connection between

the high-speed bus in the router and the external networks. The PA-2H port adapter can be installed

in the following slots on the hardware platforms described in this document:

• VIP2—Port adapter slot 0 and port adapter slot 1

• Catalyst RSM/VIP2—Port adapter slot 0 and port adapter slot 1

• Cisco 7200 series routers—Port adapter slot 1 through 6 in the Cisco 7206, or slots 1 through 4

in the Cisco 7204

• Cisco uBR7200 series routers—Port adapter slot 1 or slot 2 of the Cisco uBR7246, and port

adapter slot 1 for the Cisco uBR7223.

Each HSSI port is a female, 50-pin, SCSI-II-type receptacle. You must use an HSSI interface cable

to connect the interface with an external data service unit (DSU). Refer to the “Receptacles, Cables,

and Pinouts” section on page 1-4 for descriptions of HSSI cables.
