all electrical current from the server, you must unplug the server power
cords from the electrical outlets or from the uninterruptible power
device.
Power-on LED: When this green LED is on, power is present in the server.
When this LED flashes, the server is in Standby mode (the system operating
system is turned off and ac current is present). When this LED is off, the power
subsystem, the ac power, or an LED has failed.
POST-complete LED: This green LED is on when POST is completed without
any errors.
Hard disk drive activity LED: This green LED flickers when there is activity on
ahard disk drive.
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. See “Viewing error logs from the Configuration/Setup
Utility program” on page 32 for instructions for viewing the Error log. Check the
diagnostic LED panel for more detailed information (see “Diagnostic panel
system error LED” on page 132.
System-error LED: This amber LED is on when asystem error occurs. An LED
on the diagnostic LED panel will also be on to further isolate the error. (For
more information, see “Diagnostic panel system error LED” on page 132.)
Ethernet transmit/receive activity LED: When this green LED is on, there is
activity between the server and the network.
Chapter 1. General information 7

Server power features
This section contains information about how to properly turn your server on and off.
Turning on the server
Turning on the server refers to the act of plugging the power cords of your server
into the power source and starting the operating system.
You can turn on the server in any of the following ways:
vIf the power cords are connected to apower source, you can press the
power-control button on the front of the server.
Notes:
1. You can install acircular disk over the power-control button to prevent
accidental manual power-off. This disk, known as the power-control button
shield, comes with your server.
2. After you plug the power cords of your server into the electrical outlets, wait
approximately 20 seconds before pressing the power-control button. During
this time, the system-management adapter is initializing; therefore, the
power-control button does not respond.
v
If the server is turned on and apower failure occurs, the server will restart
automatically when power is restored.
vIf ac power is present, the server is in Standby mode, and the server is
connected to an ASM interconnect network which contains at least one system
with an optional Remote Supervisor Adapter installed, the server can be turned
on from the Remote Supervisor Adapter user interface.
vIf ac power is present, the server is in Standby mode, and an optional Remote
Supervisor Adapter is installed in the server, the server can be turned on from
the Remote Supervisor Adapter user interface.
vWhen you plug in your server for the first time, Wake on LAN
® can turn on the
server.
vIf your server was previously turned on, it must be properly placed in Standby
mode for the Wake on LAN feature to turn on the server.
8xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide

Complete the following steps to manually turn on the server:
1. Review the information in “Safety information” on page 169.
2. Turn on all external devices, such as the monitor.
3. Plug the server power cords into the power source.
4. Press the power-control button on the front of the server.
Note: While the server is powering up, the power-on LED on the front of the
server is lit.
Turning off the server
Turning off the server refers to the act of disconnecting the server from the power
source.
Complete the following steps to manually turn off the server:
1. Review the information in “Safety information” on page 169.
2. See your operating system documentation for the proper procedure to shut
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.

3. Press the power-control button on the front of the server. This will put the server
in Standby mode.
Note: You might need to press and hold the power-control button for more than
4seconds to cause an immediate shutdown of the server and to force it

for your system to stop running. Watch for the power-on LED on the front
of the server to stop flashing.
Standby mode
Standby mode refers to the condition in which the server is connected to an ac
power source but the server operating system is not running and all core logic is
shut down except for the service processor. In Standby mode, the server can
respond to service processor requests, such as aremote request to turn on the
server. When the server is in Standby mode, the power-on LED on the front of the
server flashes (when the server is running, the power-on LED stays on and does
not flash).

critical system failure. You can also put the server into Standby mode remotely by
means of an optional Remote Supervisor Adapter or through connection to an ASM
interconnect network.
