LAN Connector
LEDs
The three LAN ports (connectors) on the rear panel have the following LEDs.
„ LINK/ACT LED
The LINK/ACT LED indicates the state of each network port normally equipped with the
server. If the power is supplied to the server and the hub and they are correctly connected
with each other, the LED is lit green (LINK state). If information is transmitted through a
network port, the LED blinks green (ACT state).
If the LED is not lit in the LINK state, check the network cable and the cable connection.
If the LED is not lit still after the checking, the network (LAN) controller may be defected.
Contact your service representative.
„
1000/100/10 LED
The 1000/100/10 LED indicates whether the LAN1 to LAN4 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.
„ 100/10 LED
The 100/10 indicates whether the management LAN port 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.
