Disk expansion modules
For power-on instructions, refer to the documentation that came with the
hardware.
Before you begin
Important:
Precautions must be taken when turning on the disk expansion
modules to prevent damage to the modules' enhanced disk drive module (E-DDM)
hard drives. Carefully read all of the related information provided in the disk
expansion module documentation before turning on the power.
Disk controllers
For power-on instructions, refer to the documentation that came with the specific
disk controller(s) in the installation.
Before you begin
Important: Precautions must be taken when turning on the disk expansion

Servers
Turn on the servers using the information in this section.
About this task
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,
such as a remote request to turn on the server. The power-on LED flashes to
indicate that the server is connected to AC power but not turned on.
Approximately 20 seconds after the server is connected to AC power, the
power-control button becomes active, and one or more fans might start running to
provide cooling while the server is connected to power.
v To turn on the servers, press the white, recessed power-control button on the
server operator panel. See Figure 29 on page 71.
