Rear view CD/DVD drive activity LED: When this LED is lit, it indicates that the CD-RW/DVD drive is in use. Rack release latches: Press these latches to release the server from the rack. The following illustration shows the connectors and LEDs on the rear of the server. DC power LED AC power LED Power cord connector Optional External SAS connector Systems-management Ethernet connector Ethernet activity LEDs Ethernet link LEDs Power supply 1 Serial connector Power-on LED System-locator LED System-error LED Video connector Ethernet 1 connector USB 4 connector Ethernet 2 connector USB 3 connector USB 1/USB 2 connectors 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 the Problem Determination and Service Guide on the IBM System x Documentation CD. 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 the Problem Determination and Service Guide on the IBM System x Documentation CD. Optional external SAS connector: Connect a serial-attached SCSI (SAS) device to this connector. 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. Chapter 3.

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
