Chapter 2. Power, controls, jumpers, switches, and indicators
This chapter describes the power features, how to turn on and turn off the blade
server, what the controls and indicators mean, and where the system board jumpers
and switches are located and how to use them.
Turning on the blade server
After you connect the blade server to power through the BladeCenter unit, the blade
server can start in any of the following ways:
v
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
14) to start the blade server.
Notes:
1. Wait until the power-on LED on the blade server flashes slowly before
pressing the blade server power-control button. During this time, the service
processor in the management module is initializing; therefore, the
power-control button on the blade server does not respond.
2. While the blade server is powering-up, the power-on LED on the front of the
server is lit. See “Understanding the control panel and LEDs” on page 14 for
the power-on LED states.
v
If a power failure occurs, the BladeCenter 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).
v
You can turn on the blade server remotely by means of the service processor in
the management module.
v If the operating system supports the Wake on LAN feature and the blade server
power-on LED is flashing slowly, the Wake on LAN feature can turn on the blade
server, if the Wake on LAN feature has not been disabled through the
management-module.
