EFDMIM LEDs
This section provides an overview of the LEDs. For more detailed information,
refer to the manual that came with your hardware. The EFDMIM LEDs are
grouped into three categories: General, FDDI, and MMAC (Ethernet). During
operation of the EFDMIM, the LANVIEW LEDs can be interpreted as follows:
General LEDs
POWER
When lit, this green LED indicates that the power is on for the MMAC in
which the EFDMIM is installed and the EFDMIM is receiving power.
SYSOK
When lit, this green LED indicates that the EFDMIM internal self-test was
completed successfully. This self-test is run each time you power on the unit.
STANDBY
When lit, this yellow LED indicates that the bridge is in standby and no
packets are being forwarded. OFF is the normal mode with packets being
forwarded across the bridge.
FDDI Interface LEDs
TX
When flashing, this green LED indicates that data is being sent out on the
FDDI ring interface.
RX
When flashing, this yellow LED indicates that data is being received from the
FDDI ring interface.
WRAP
When lit, this red LED indicates that the EFDMIM is in a wrap condition.
OFF is the normal state.
TOKISD
This green LED flashes each time the EFDMIM places the token on the FDDI
ring.
ON NET
When lit, this green LED indicates that the EFDMIM’s FDDI interface is
inserted into the FDDI ring network. OFF indicates that the EFDMIM is
removed from the ring.
LINK A/B
When lit, these green LEDs indicate that an optical signal is being detected.
