LED Function
COL Indicates that the port has either detected an Ethernet wire collision
in Simplex mode, or is transmit-congested in Duplex mode.
LNK Indicates that the port has established a valid link with another node
or repeater in 10-MB mode.
TX and RX Indicate when the port is transmitting and receiving data.
SPD Remains lit when the port is in 100-MB mode. The SPD LED does
not light when the port is in 10-MB mode.
DPX Indicates that the port is in Duplex mode and is sending and
receiving.
FAIL Lights during powerup, and may flash during diagnostic testing. This
LED turns off after the diagnostics complete successfully and the BN
platform boots. It remains lit if the link module or any connector on
the link module fails diagnostics. In this case, the DIAG LED on the
BN front panel will also be on, and you should contact the Bay
Networks Technical Response Center.
