Indicates the administrative status (enabled or disabled). The
status indicators are:
■ Green—Administrative status enabled.
■ Unlit—Administrative status disabled.
LED: ADM Status
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.
LED: DPX
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:
■ No device that draws power from the port is
connected to the port.
■ 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.
