Description
When lit, this amber LED on the left side of the line card
indicates that the line card is offline (powered off) but is ready
for hot swap.
The Offline LED also is lit briefly during a reboot or reset of the
XP but goes out as soon as the control module discovers the
line card.
When lit, this green LED indicates that the line card is online
and is ready to receive, process, and send packets if configured
to do so.
Each port has two LEDs located to the left of the connector.
The green Lnk LED indicates the link status. When this LED is
lit, the port hardware is detecting that a cable is plugged into
the port and the port has established communication with the
device at the other end.
The amber Act LED flashes each time the port's transceiver
sends or receives packets.
