The following illustration shows the connectors and LEDs on the rear of the server.
Power-cord
connector
Power-cord connector: Connect the power cord to this connector.
Activity LEDs (Ethernet): These green LEDs are on the dual Ethernet connector.
When either LED flashes, it indicates that data is being transmitted or received
between the server and the network device that is connected to the left or right
connector. The flashing frequency is proportional to the amount of traffic on the
network link.
Link LEDs (Ethernet): These LEDs are on the dual Ethernet connector. When
either LED is lit, it indicates that there is an active link between the server and the
network device that is connected to the left or right connector.
System-error LED: When this LED is lit, it indicates that a system error has
occurred. An LED near the failing component on the system board is also lit to help
isolate the error. A system-error LED is also on the front of the server.
Power-on LED: When this LED is lit and not flashing, it indicates that the server is
turned on. When this LED is flashing, it indicates that the server is turned off and
still connected to an ac power source. When this LED is off, it indicates that ac
power is not present, or the power supply or the LED itself has failed. A power-on
LED is also on the front of the server.
Note: If this LED is off, it does not mean that there is no electrical power in the
Gigabit Ethernet 1 (LAN 1) connector: Use this connector to connect the server
to a network.
Gigabit Ethernet 2 (LAN 2) connector: Use this connector to connect the server
to a network.
USB connectors: Connect a USB device to either of these connectors.
Video connector: Connect a monitor to this connector.
Serial connector: Connect a 9-pin serial device to this connector.
