Description
Offline
When lit, this amber LED on the left side of the module indicates that
the module is offline (powered off) but is ready for hot swap.
The Offline LED also is lit briefly during a reboot or reset of the RS but
goes out as soon as the Control Module discovers the module.

When lit, this green LED indicates that the module is online and is ready
to receive, process, and send packets if configured to do so.
Per-port Loop
Off
– indicates normal operations.
Blinking Green
– remote loopback; Tx is looped back into Rx outside
this device.
Green
– local loopback; Tx is looped back into Rx before leaving this
device.
Yellow
– the network has placed this port in loopback; Rx is looped back
out to Tx within this device
Blinking Yellow

indicates that the line card has a connection to the upstream device; but
the upstream device has lost its receive connection to the network and is
sending an AIS to indicate this.

and a good link is established.
