Cabling I/O Modules

This section illustrates the common connector types used with ERX I/O modules. For information about the connectors on the different line modules, see the ERX Module Guide.

HSSI Connectors

The HSSI I/O module uses a standard 50-pin HSSI connector.

CAUTION: Do not terminate HSSI connections with SCSI connectors. Although SCSI connectors look very similar to HSSI connectors, using SCSI connectors on HSSI connections can lead to data loss.
