LAN LEDs
The LED indicators on the Ethernet LAN connectors are described below.
• LINK/ACT LED:
The LINK/ACT LED shows the status of a standard network port. It is green if power is supplied
to the main unit and hub and they are connected correctly (LINK). It blinks green while the
network port sends or receives data (ACT).
When the LED does not illuminate during LINK, check the condition and connection of network
cables. If there is nothing wrong with the cables, a defect is suspected in the network (LAN)
controller. In this case, contact Customer Service.
• Speed LED:
This LED indicates the network interface of the communication mode used by a network port.
1000BASE-T and 100BASE-TX are the supported LAN port types. When this LED illuminates
in amber, the port is operating on 1000BASE-T; when in green, 100BASE-TX; and when not
illuminate, 10BASE-T.
Power supply unit LED
When the power supply unit has a failure, the amber LED light will light. There are two power
supplies per system.
