2.4.3 Connecting Dual-homed Single-attached Stations
Two cable assemblies are required for each ATX. One consists of a fiber
cable with a MIC A plug on one end and a MIC M plug on the other end,
and the second consists of a fiber cable with a MIC B plug on one end and
a MIC M plug on the other end.
1. Attach the MIC A plug on the end of the first cable assembly to the
receptacle labeled “FDDI MIC A” on the module front panel
(Figure 2-8).
2. Attach the MIC M plug on the other end of the first cable to the master
port MIC M receptacle on the first DAC.
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 M plug on the other end of the second cable to the
master port MIC M receptacle on the second DAC.
5. Check the LEDs. In this configuration the RING B RX, TX and
WRAP LEDs will be on.
2.4.4 Connecting Single-attached Stations
The cable assembly consists of one fiber cable with a MIC B plug on one
end and a MIC M plug on the other end.
Warning: When you are using a single-mode cable, do not look at the
end of the cable. The single-mode cable uses a laser, which could cause
damage to your eye if you look directly into it.
1. Attach the MIC B plug on one end of the cable assembly to the
receptacle labeled “FDDI MIC B” on the module front panel
(Figure 2-8).
2. Attach the MIC M plug on the other end to the master port MIC M
receptacle on the DAC.
3. Check the LEDs. In this configuration the RING B RX, TX and
WRAP LEDs will be on.
