2.4.2 Connecting Dual-attached Stations
The cable assembly consists of a fiber cable (either multimode or single
mode, depending on the type of module you are using) with a MIC A plug
on one end and a MIC B plug on the other end. Two cable assemblies are
required for each ATX that you are connecting.
Note: Remember, when DASs are connected on an FDDI ring, A ports
(MIC A) must be connected to B Ports (MIC B), and B ports must be
connected to A ports.
1. Attach the MIC A plug on the end of one cable assembly to the
receptacle labeled “FDDI MIC A” on the module front panel
(Figure 2-8).
2. Attach the MIC B plug on the other end to the MIC B receptacle on the
first DAS.
3. Attach the MIC B plug on the end of the second cable assembly to the
receptacle labeled “FDDI MIC B” on the module front panel
(Figure 2-8).
4. Attach the MIC A plug on the other end of the second cable to the MIC
A receptacle on the second DAS.
5. Check the LEDs. In this configuration the RING A RX, TX and THRU
LEDs will be on.
