Removing the Subassembly

You need to remove the subassembly if you are installing your

first hard disk drive, removing your only hard disk drive, or

installing or removing a hard disk drive that is mounted next to

the power supply.

Follow these steps:

1. Turn the computer so you are facing its front side.

2. Disconnect the power supply and drive cables from the backs

of all the drives installed in your computer. Note which

cables are connected to which drives so you can easily

reconnect them later.

3. Open the clasps holding the power supply and drive cables

to the side of the subassembly, as shown in the following

illustration. Then remove all the cables from the clasps.
