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.
Online
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.
Amber
– the network has placed this port in loopback; Rx is looped
back out to Tx within this device
Blinking Amber
– the Alarm Indication Signal (AIS)/ Blue Alarm. It
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.
Per-port Link
Green
– indicates that the line card detects a cable plugged into the port
and a good link is established.
Blinking Green
– Port is in transition to active state
Amber
– indicates that the port was disabled by management.
Off
– indicates that the port is not configured (i.e., there are no time slot
assignments).
Per-port Tx
Flashing Green
– indicates that the port’s transceiver is transmitting
data.
Blinking Amber
– the Remote Alarm Indication (RAI)/Yellow Alarm
signal. The remote device is in a Red alarm condition (it is not receiving
a signal from the line card). This is a framed indication.
Per-port Rx
Flashing Green

Blinking Amber
– the Red alarm. Indicates a loss of signal (LOS) or
loss of framing (LOF) on the Rx side.
