4xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide

vSystem power-on LED: When this LED is lit and not flashing, it indicates that
the server is turned on. When this LED is flashing, it indicates that the server is
turned off and still connected to an ac power source. When this LED is off, it
indicates that ac power is not present, or the power supply or the LED itself has
failed. Apower LED is also on the rear of the server.
vOK LED: This green LED is lit only when the Front Panel LED test is performed
by the Enhanced Diagnostics.
vHard disk drive activity LED: When this green LED is flashing rapidly it
indicates that there is activity on ahard disk drive.
vSystem-information LED: When this amber LED is on, the server power
supplies are nonredundant, or some other noncritical event has occurred. The
event is recorded in the error log. Check the light path diagnostic panel for more
information (see the “Light path diagnostics” on page 93.
vSystem-error LED: When this amber LED is lit it indicates that asystem error
has occurred. Use the diagnostic LED panel and the system service label on the
inside of the left-side cover to further isolate the error. See “Light path
diagnostics” on page 93 for additional information.
vSystem locator LED: Use this LED to visually locate the server among other
servers. You can use IBM Director to light this LED remotely.
vEthernet transmit/receive activity LED (Tx/Rx 1or Tx/Rx 2): When these two
green LEDs are lit they indicate that there is activity between the server and the
network.
USB 3connector: Connect aUSB device to this connector.
Diskette-eject button: Press this button to release adiskette from the diskette
drive.
Diskette drive activity LED: When this LED is lit, it indicates that the diskette drive
is in use.
Hard disk drive activity LED: When this LED is flashing, it indicates that the
associated hard disk drive is in use.
Hard disk drive status LED: When this LED is lit, it indicates that the associated
hard disk drive has failed. If an optional RAID adapter is installed in the server and
the LED flashes slowly (one flash per second), the drive is being rebuilt. If the LED
flashes rapidly (three flashes per second), the controller is identifying the drive.
Reset button: Press this button to reset the server and run the power-on self-test
(POST). You might have to use apen or the end of astraightened paper clip to
press the button.
Power-control button: Press this button to turn the server on and off manually. A
power-control-button shield comes with the server. You can install this disk-shaped
shield to prevent the server from being turned off accidentally.
Power-control-button shield: You can install this circular disk over the
power-control button to prevent the server from being turned off accidently.
CD-ROM drive activity LED: When this LED is lit, it indicates that the CD-ROM
drive is in use.
CD-eject button: Press this button to release aCD from the CD-ROM drive.

other combination of LEDs, see “Light path diagnostics” on page 93.
6xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide

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. For any
other combination of LEDs, see “Light path diagnostics” on page 93.
Power-cord connector: Connect the power cord to this connector.
Ethernet Activity LED: This LED is on the Ethernet connector. When it flashes, it
indicates that data is being transmitted or received between the server and the
network device that is connected to the connector. The flashing frequency is
proportional to the amount of traffic on the network link.
ASM: Use this connector to connect the server to an Advanced System
Management (ASM) network.
Ethernet link status LED: This LED is on the Ethernet connector. When this LED
is lit, there is an active connection on the Ethernet port.
Remote Supervisor Adapter II SlimLine Ethernet: Use this connector to connect
the server to an optional Remote Supervisor Adapter II SlimLine installed in another
server. This connector is enabled when the Remote Supervisor II SlimLine option is
installed.
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
(also called the baseboard management controller), such as aremote 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
Approximately 20 seconds after the server is connected to ac power, the
power-control button becomes active, one or more fans might start running, 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:
vIf apower failure occurs while the server is turned on, the server will restart
automatically when power is restored.
vIf the server is connected to an Advanced System Management interconnect
network that contains at least one server with an optional Remote Supervisor
Adapter installed, the server can be turned on from the Remote Supervisor
Adapter user interface.
vIf your operating system supports the systems-management software for an
optional Remote Supervisor Adapter, the systems-management software can turn
on the server.
vIf your operating system supports the Wake on LAN®feature, the Wake on LAN
feature can turn on the server.
Chapter 1. General information 7

Note: When 4GB 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.
Turning off the server
When you turn off the server and leave it connected to ac power, the server can
respond to requests from the service processor, such as aremote request to turn
on the server. While the server remains connected to ac power, one or more fans
might continue to run. To remove all power from the server, you must disconnect it
from the power source.
Some operating systems require an orderly shutdown before you turn off the server.
See the operating-system documentation for information about shutting down the
operating system.
Statement 5
CAUTION:
The power control button on the device and the power switch on the power supply do
not turn off the electrical current supplied to the device. The device also might have
more than one power cord. To remove all electrical current from the device, ensure
that all power cords are disconnected from the power source.

2
The server can be turned off in any of the following ways:
vYou can turn off the server from the operating system, if your operating system
supports this feature. After an orderly shutdown of the operating system, the
server will be turned off automatically.
vYou can press the power-control button to start an orderly shutdown of the
operating system and turn off the server, if your operating system supports this
feature.
vIf the operating system stops functioning, you can press and hold the
power-control button for more than 4seconds to turn off the server.
vIf the server is connected to an Advanced System Management interconnect
network that contains at least one server with an optional Remote Supervisor
Adapter installed, the server can be turned off from the Remote Supervisor
Adapter user interface.
vIf an optional Remote Supervisor Adapter is installed in the server, the server can
be turned off from the Remote Supervisor Adapter user interface.
vIf the Wake on LAN feature turned on the server, the Wake on LAN feature can
turn off the server.
vThe integrated system management processor can turn off the server as an
automatic response to acritical system failure.
vYou can turn off the server through arequest from the service processor.
