Overview of Installation and Removal

Install/remove components by using the following procedure.
Installing/removing internal components except for Hard Disk Drives should be done after dismounting the
server from the rack. It is recommended that more than one person removes the server from the rack.
1. If the server is mounted on a rack, use the UID switch to identify the target server.
Refer to Chapter 2 (1.4 Confirming Servers (UID Switch)).
2. Remove the front bezel if applicable.
Refer to Chapter 2 (1.5 Removing the Front Bezel).
3. If the server is ON, turn it off.
Refer to Chapter 3 (6. Turning Off the Server).
4. Disconnect the power cord from the outlet and the server.
5. When installing or removing the Internal Flash Memory, DIMMs, RAID Controllers, PCI cards, or
optical disk drives, dismount the server from the rack and place it on a flat and hard desk. If installing
only an additional hard disk drive, go to step 7.
Refer to Chapter 2 (2.1.2 Installing the server to the rack or removing it from the rack – (2) Removal
procedure).
Be sure to observe the following precautions to use the server safely. Failure to
observe the precautions may cause burns, injury, and property damage. For
details, refer to Safety precautions in Precautions for Use.
• Do not drop the server
• Do not leave the server pulled out of the rack
• Replace the cover after installing components
• Beware of high temperatures

seconds before continuing to work because the components on the
motherboard might still be operating for 3 to 4 seconds even after the power
cord was disconnected.
Important
Do not leave the server open on the rack.
