State and Description
Indicates the administrative status (enabled or disabled). The status indicators are:
Green—Administrative status enabled.
Unlit—Administrative status disabled.
Indicates the duplex mode.
The uplink module ports are always set to full-duplex; therefore, the LED is always green.
The status indicators for network ports on the front panel are:
Green—Port is set to full-duplex mode.
Unlit—Port is set to half-duplex mode.
Indicates the PoE status.
PoE is not enabled on uplink module ports; therefore, the LED for those ports is always unlit.
The status indicators for network ports on the front panel are:
Green—PoE is enabled on the port.
Amber—PoE is enabled on the port, but no power is drawn from the port because of one of the
following:

A device that draws power from the port is connected to the port, but the device is not drawing
any power from the port.
Unlit—PoE is not enabled on the port.
Indicates the speed.
The speed indicators for network ports on the front panel are:
One blink per second—10 Mbps
Two blinks per second—100 Mbps
Three blinks per second—1000 Mbps
The speed indicators for network ports on the SFP uplink module are:
Green—1000 Mbps
Unlit—10/100 Mbps
The speed indicators for network ports on the SFP+ uplink module are:
Green—The speed of the transceiver installed in the port is the same as the speed at which the
uplink module port is configured to operate.
Unlit—The speed of the transceiver installed in the port is not the same as the speed at which
the uplink module port is configured to operate.
