The following illustration shows the connectors and LEDs on the rear of the server.
Power supply 1
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. 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. 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.
Optional external SAS connector: Connect a serial-attached SCSI (SAS) device
to this connector.
System-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 is
used only by the Remote Supervisor Adapter II SlimLine.
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 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 connectors: Use either of these connectors to connect the server to a
network.
USB connectors: Connect a USB device, such as a USB mouse, keyboard, or
other USB device, to any of these connectors.
Video connector: Connect a monitor to this connector.
Power-on LED: When this LED is lit and not flashing, it indicates that the server is
