Cisco HSSI cable - HD-50 (M) - HD-50 (M) - 3 m CAB-HSI1 Manual De Usuario

The Cisco 7206 can be used as a router shelf in a Cisco AS5800 Universal Access Server. The steps for 
installing HSSI cables on a Cisco 7200 series router and a Cisco 7206 router shelf are the same. The 
procedures that reference the Cisco 7200 series also apply to the Cisco 7206 router shelf, unless 
otherwise noted.

Sections in this publication include the following:

Each HSSI port on the HIP, PA-H, PA-2H, or NP-1HSSI uses a female, 50-pin, SCSI-II-type connector. 

Although the HSSI connector and the HSSI cable are similar to SCSI-II format, they are not identical. 
The HSSI cable specification is more stringent than that for SCSI-II. If you use a SCSI-II cable instead 
of an HSSI cable, proper operation cannot be guaranteed.

Two types of cables are available for use with a HSSI ports:

HSSI cable (CAB-HSI1[=]) used to connect your router to an external DSU (and the HSSI network)

Null modem HSSI cable (CAB-HNUL[=]) used to connect two routers back-to-back

For information on how to enable two routers for back-to-back operation, refer to the configuration notes 
for the HIP, PA-H, PA-2H, or NP-1HSSI.
