Cabling I/O Modules
The following sections describe how to cable I/O modules with different
types of connectors. For information about the connectors on the
different line modules, see Appendix B, Module Specifications.
Cabling BNC Connectors
To cable I/O modules with BNC connectors:
1 Insert the RX male BNC connector into the selected port.
2 Terminate the other end in the appropriate network interface, such
as a multiplexer (MUX) device.
3 Repeat steps 1 and 2 for the TX connector.
4 Repeat steps 1–3 for all ports.

Cabling 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 may lead to data loss.
