LED Condition Description
Offline Amber 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
X-Pedition but goes out as soon as the control module discovers the
line card.
Online Green 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.
Lnk Green 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.
Act Amber The amber Act LED flashes each time the port’s transceiver sends or
receives packets.
