Keyboard connector: Connect a PS/2 (non-USB) keyboard to this connector.
Serial connector: Connect a serial device to this connector.
RXE Management Port: Connect the RXE Management A (In) Port of an optional
IBM RXE-100 Remote Expansion Enclosure to this connector (see “RXE connector
cabling” on page 60).
Power-supply connector: Connect one end of the power-supply power cord to this
connector and connect the other end to an ac power source. The server comes with
one or two hot-swap power supplies, depending on the configuration. You can add
a second hot-swap power supply to obtain full power redundancy. Connect each
power supply to an ac power source for power redundancy.
SCSI connector: Connect an external SCSI device to this connector.
Light path diagnostics LED panel
Swing the operator information panel out to see the light path diagnostics LED
panel on the side surface (see “Light path diagnostics” on page 18 and “Light path
LED errors” on page 93).
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 service processor is
shut down; however, the server can respond to requests from the service processor,
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 not turned on.
Turning on the server
Approximately 20 seconds after the server is connected to ac power, the
power-control button becomes active, and you can turn on the server and start the
operating system by pressing the power-control button.
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 the server is connected to an Advanced System Management interconnect
network that contains at least one server with a Remote Supervisor Adapter or
Remote Supervisor Adapter II installed, the server can be turned on from the
Remote Supervisor Adapter or Remote Supervisor Adapter II user interface.
v The system-management software for the Remote Supervisor Adapter II in your
server can turn on the server.
v If your operating system supports the Wake on LAN feature, the Wake on LAN
feature can turn on the server.
Note: When 4 GB or more of memory (physical or logical) is installed, some
memory is reserved for various system resources and is unavailable to the
operating system. The amount of memory that is reserved for system
resources depends on the operating system, the configuration of the server,
and the configured PCI options.
