AC power LED
This green LED provides status information about the power supply. During
typical operation, both the ac and dc power LEDs are lit.
DC power LED
This green LED provides status information about the power supply. During
typical operation, both the ac and dc power LEDs are lit.
Fault-error LED
When this yellow LED is lit, it indicates that the power supply has failed.
Serial connector
Connect a 9-pin serial device to this connector. The serial port is shared
with the integrated management module II (IMM2). The IMM2 can take
control of the shared serial port to redirect serial traffic, using Serial over
LAN (SOL).
Video connector
Connect a monitor to this connector.
USB connectors
Connect USB devices to these connectors.
NMI button
Press this button to force a nonmaskable interrupt to the microprocessor. It
allows you to blue screen the server and take a memory dump (use this
button only when directed by the IBM service support). You might have to
use a pen or the end of a straightened paper clip to press the button.
Ethernet connector
Use either of these connectors to connect the server to a network. When
you use the Ethernet 0 connector, the network can be shared with the
IMM2 through a single network cable.
Ethernet transmit/receive activity LED
This LED is on the Ethernet connector. When this LED is flashing, it
indicates that there is activity between the server and the network.
Ethernet link status LED
This LED is on the Ethernet connector. When this LED is lit, it indicates that
there is an active connection on the Ethernet port.
Server power features
When the server is connected to an ac power source but is not turned on, the
operating system does not run, and all core logic except for the integrated
management module II (IMM2) is shutdown; however, the server can respond to
requests from IMM2, such as a remote request to turn on the server. The power-on
LED flashes to indicate that the server is connected to ac power but is not turned
on.
Turning on the server
Note: Approximately 1 to 3 minutes after the server is connected to ac power, the
power-control button becomes active after the power-on LED flashes slowly.
The server can also be turned on in any of the following ways:
v If a power failure occurs while the server is turned on, the server will restart
automatically when power is restored.
v If your operating system supports the Wake on LAN feature, the Wake on LAN
feature can turn on the server.
