Power, Controls, Jumpers,
Switches, and Indicators
This chapter describes the power features, how to turn on and turn off the blade server,
and what the controls and indicators mean. This chapter also identifies the system-board
connectors.
Turning on the Blade Server
After you connect the blade server to power through the SBCE unit, the blade server can
start in any of the following ways:
•
You can press the power-control button on the front of the blade server (behind the
control panel door, see “Understanding the Control Panel and LEDs” on page 10 ) to
start the blade server.
Notes:
1. Wait until the power-on LED on the blade server flashes slowly before pressing the
power-control button. While the service processor in the management module is
initializing, the power-on LED does not flash, and the power-control button on the
blade server does not respond.
2. While the blade server is starting, the power-on LED on the front of the blade server
is lit. See “Understanding the Control Panel and LEDs” on page 10 for the power-on
LED states.
•
If a power failure occurs, the SBCE unit and then the blade server can start
automatically when power is restored, if the blade server is configured through the
management module to do so.
•
You can turn on the blade server remotely by using the management module.
•
If the blade server is connected to power (the power-on LED is flashing slowly), the
operating system supports the Wake on LAN feature, and the Wake on LAN feature
has not been disabled through the management module, the Wake on LAN feature can
turn on the blade server. However, the blade server can only receive the Wake on LAN
command through the Ethernet ports that are integrated on the system board, not
through the Ethernet ports on an installed I/O expansion card.
Turning off the Blade Server
When you turn off the blade server, it is still connected to power through the SBCE unit.
The blade server can respond to requests from the service processor, such as a remote
request to turn on the blade server. To remove all power from the blade server, you must
remove it from the SBCE unit.
