Preparing Your Server for Upgrade
To prepare your server for installation or removal
1. Observe the safety and static precautions listed under “General Information”

2. Shutdown the operating system (OS).
It is not necessary to shutdown to replace hot-swappable components, such as
the hard disk drives and the additional power supply units, if applicable.
3. Unlock and remove the front bezel. ( See “Removing the Front Bezel” on
page 56. )

4. Power off the server then press the POWER switch on the front panel of the
server.
The POWER lamp goes out.
5. Unplug the server power cord(s) from the AC wall outlet(s).
Note: If the server power cord is connected to a power
control unit such as an UPS (Uninterruptible Power Supply),
refer to the UPS user's guide for proper power-off procedures.
6. Unplug the I/O cables connected to the rear panel of your server.
The server needs to be pulled out from the rack for installing/removing any internal
components other than the hard disk drives and power supply units (redundant power
supply model only).
