LAN Connector Lamps
LAN1 and LAN2 connectors on the rear panel have two lamps as follows.
LINK/ACT lamp
1000/100/10 lamp
LAN port 1
1000/100/10 lamp
LAN port 2
„ LINK/ACT lamp
The link/ACT lamp 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 lamp is lit green
(LINK state). If information is transmitted through a network port, the lamp blinks green (ACT state).
If the lamp is not lit in the LINK state, check the network cable and the cable connection. If the lamp is not lit
still after the checking, the network (LAN) controller may be defected. Contact your service representative.
„ 1000/100/10 lamps
The 1000/100/10 lamp indicates whether the LAN2 port normally equipped with the server is operated
through the 1000BASE-T, 100BASE-TX or 10BASE-T network interface. If the lamp is lit amber, the
network port is operated through 1000BASE-T. If the lamp is lit green, the network port is operated through
100BASE-TX. If the lamp is off, the network port is operated through 10BASE-T.
