Chapter 2. Power, controls, 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
The QS22 blade server is hot-swappable and can be inserted into the BladeCenter
unit when the unit is already powered up. However, it can only be powered on by
one of the methods described in this section. While the blade server is powering up,
the power-on LED on the front of the server is lit. See "Blade server controls and
LEDs" on page 10 for the power-on LED states.
After you have installed the blade server into a powered up BladeCenter unit, wait
until the power on LED on the blade server flashes slowly before turning on the
blade server.
You can turn on the blade server in any of the following ways:
Using the power-control button
Figure 3. Blade server power-control button
Using the BladeCenter Advanced Management Module
Using the Wake on LAN
In the event of a power failure the BladeCenter unit and then the blade server can
start automatically when power is restored. You must configure this through the
BladeCenter Advanced Management Module. See the BladeCenter Management
Module User's Guide for further information about this feature.

Providing local power control is enabled, you can press the power-control
button (see Figure 3) which is behind the control-panel door on the front of
the blade server. Local power control is enabled or disabled through the
Advanced Management Module Web interface.
You can use the Advanced Management Module Web interface to turn on
the blade server remotely.
