3.5 Connecting Cables and Connectors
Refer to your Option Card Installation manual for the following information:
1. Identifying the connector and port type
2. Connecting the cable to the appropriate connector and port
3. Observing the LEDs when you are connecting the cables
4. Adding the cable identification numbers to the DECconcentrator 500 Identifi-
cation List in Appendix B
When connecting cables, use the following guidelines:
– Bridges, workstations, and other single attachment stations (SAS) connect
to the M ports on the Port Card.
– A concentrator or dual attachment station (DAS) participating in a dual
ring connects to the dual ring through Ports A and B on the Network
Management Card. Cabling goes from Port B of the upstream concentra-
tor or DAS to Port A.
– In a tree configuration, a concentrator or DAS B port connects to a con-
centrator M port.
To use the out-of-band management, go to Chapter 4.
