LAN Connector LEDs

There are two LEDs for each of the two LAN ports (connectors) on the rear panel.
LINK/ACT LEDs
Each LINK/ACT LED indicates the status of the standard network port of the server.
While power is supplied to the server and HUB and the connection is correct, the LED is
on (green). The LED turns green and flashes while the network port is
transmitting/receiving data.
If the LED does not go on when the LINK state is placed, check if the network cable is in
normal state and if it is connected correctly. If the LED does not go on yet when the
network cable is normal, the network (LAN) controller may be faulty. In this case, contact
your sales representative.
Speed LEDs (for data transmission ports)
This LED indicates whether each of the network ports normally equipped with the server
is operated through the 1000BASE-T, 100BASE-TX or 10BASE-T network interface. If
the LED is lit amber, the network port is operated through 1000BASE-T. If the LED is lit
green, the network port is operated through 100BASE-TX. If the LED is off, the network
port is operated through 10BASE-T.
Speed LED (for management port)
This LED indicates whether each of the network ports normally equipped with the server
is operated through the 100BASE-TX or 10BASE-T network interface. If the LED is lit
green, the network port is operated through 100BASE-TX. If the LED is off, the network
port is operated through 10BASE-T.
