3F00-01 LEDs
The LED power-up sequence for the 3F00-01 is as follows:
1. All LEDs light briefly and turn off, except for the PWR LED, which
remains on.
2. The STATUS LED lights while power-up diagnostics are being run on
the 3F00-01.
3. The TX and RX LEDs flash.
4. The STATUS LED goes off while diagnostics are running on the other
modules in the ATX.
5. The STATUS LED lights again when the 3F00-01 software initializes
and remains on.
6. The RING A and RING B RX, TX, THRU, and WRAP LEDs remain
off until the module is connected to the network.
Note: RING A refers to the primary FDDI ring, and RING B to the
secondary FDDI ring. These LEDs do NOT correspond to FDDI MIC A
and FDDI MIC B.
