Cable Installation and Interface
Configuration
To continue your PA-H HSSI port adapter installation, you must install the port adapter cables and
configure the HSSI interfaces. The instructions that follow apply to all supported platforms. Minor
differences between the platforms are noted. This chapter contains the following sections:
• Attaching PA-H HSSI Port Adapter Interface Cables, page 8-1
• Attaching a Null Modem Cable to PA-H HSSI Port Adapters, page 8-2
• Configuring the HSSI Interfaces, page 8-3
Attaching PA-H HSSI Port Adapter Interface Cables
On a single PA-H, you can use one HSSI connection. HSSI cables are available from Cisco Systems;
they are not available from outside commercial cable vendors.
Caution Although the HSSI connector and the HSSI cable are similar to the SCSI-II format, they
are not identical. The HSSI cable specification is more stringent than that for the SCSI-II. If you use
a SCSI-II cable instead of an HSSI cable, proper operation cannot be guaranteed.
Connect HSSI cables to a PA-H as follows:
Step 1 Attach the HSSI cable directly to the PA-H HSSI port on the PA-H. (See Figure 8-1.)
