Installing the HP HSC FDDI/9000 Adapter

Connecting the Adapter to the Network

SC connectors are a duplex style connector where the two ﬁber leads

snap together to form a keyed connection. Make sure the Rx and Tx leads

are marked in some common scheme for your network. For example, if

the ﬁber lead with a blue ring routes Tx signals from this station, follow

this convention for all other stations.

If you are connecting your dual-attachment adapter directly to the dual

ring, proceed to the next section, “Connecting Directly to the Dual Ring.”

Otherwise, continue to Chapter 4, “Conﬁguring and Verifying HP EISA

and HSC FDDI/9000.”

Connecting Directly to the Dual Ring

This adapter can be connected directly to the dual ring by connecting the

A and B ports of its neighbors. Figure 3-7 illustrates a 3-node dual ring

topology with no concentrator. Note that the A port of each station is

connected to the B port of a neighbor, continuing around the network

until the ring is complete.
