Installing the HP EISA FDDI/9000 Adapter
Connecting the Adapter to the Network
Figure 2-2 Dual-Ring Tx/Rx Topology
Single-Attachment MIC Adapter Connections
A single-attachment station (SAS) adapter cannot be connected directly
to the FDDI ring. It must be connected to an M port on a
single-attachment concentrator (SAC). The fiber cable used to attach the
adapter is normally a MIC connection at the concentrator with M keying.
The signals must be routed such that the Tx output of one station is
routed to the Rx input of its downstream neighbor.
To connect a SAS adapter to the concentrator, do the following:
1. Connect the cable from the adapter to any available M port on the
concentrator, as shown in Figure 2-3.
