Required Equipment

• Number 2 Phillips-head screwdriver
• Number 1 Phillips-head screwdriver
• Needle-nose pliers
• Electrostatic discharge (ESD) strap or other grounding equipment such as a grounded mat
Shutting Down and Powering Off the Server
The server can run in two power modes:
• Main power mode—Power is supplied to all server components and any operating system on your
hard drives can run.
• Standby power mode—Power is supplied only to the service processor and the cooling fans and it
is safe to power off the server from this mode.
You can invoke a graceful shutdown or an emergency shutdown (hard shutdown) by using either of the
following methods:
• Use the CIMC management interface.
• Use the Power button on the server front panel. To use the Power button, follow these steps:
Step 1 Check the color of the Power Status LED (see the “Operations Panel LEDs and Buttons” section on
page 3-3).
• Green indicates that the server is in main power mode and must be shut down before it can be safely
powered off. Go to
Step 2.
• Off indicates that the server is already powered off or is in in standby mode and can be safely
powered off. Go to
Step 3.
Step 2 Invoke either a graceful shutdown or a hard shutdown:
Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown
of the operating system.
• Graceful shutdown—Press and release the Power button. The operating system will perform a
graceful shutdown and the server goes to standby mode, which is indicated by the Power Status LED
being off.
