Rear view

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.
AC power LED: Each hot-swap power supply has an ac power LED and a dc
power LED. When the ac power LED is lit, it indicates that sufficient power is
coming into the power supply through the power cord. During typical operation, both
the ac and dc power LEDs are lit. For any other combination of LEDs, see
"Power-supply LEDs" on page 53.
DC power LED: Each hot-swap power supply has a dc power LED and an ac
power LED. When the dc power LED is lit, it indicates that the power supply is
supplying adequate DC power to the system. During typical operation, both the ac
and dc power LEDs are lit. For any other combination of LEDs, see "Power-supply
LEDs" on page 53.
Systems-management Ethernet connector: Use this connector to connect the
server to a network for systems-management information control. This connector is
active only if you have installed a Remote Supervisor Adapter II SlimLine, and it is
used only by the Remote Supervisor Adapter II SlimLine.
Ethernet activity LEDs: When these LEDs are lit, they indicate that the server is
transmitting to or receiving signals from the Ethernet LAN that is connected to the
Ethernet port.
Ethernet link LEDs: When these LEDs are lit, they indicate that there is an active
link connection on the 10BASE-T, 100BASE-TX, or 1000BASE-TX interface for the
Ethernet port.
Ethernet connectors: Use either of these connectors to connect the server to a
network.
USB connectors: Connect a USB device, such as USB mouse, keyboard, or other
USB device, to any of these connectors.
Video connector: Connect a monitor to this connector. The video connectors on
the front and rear of the server can be used simultaneously.
System-error LED: When this LED is lit, it indicates that a system error has
occurred. An LED on the light path diagnostics panel is also lit to help isolate the
error.
