Removing and replacing Tier 2 CRUs
You can install a Tier 2 CRU yourself or request IBM to install it, at no additional
charge, under the type of warranty service that is designated for your computer.
The illustrations in this document might differ slightly from your hardware.
Removing the hard disk drive bracket
The hard disk drive bracket is installed on some models to provide a drive bay (bay
5) for an additional hard disk drive. When working with some devices, such as hard
disk drives, adapters, and memory modules, you must first remove the hard disk
drive bracket to access the device.
To remove the hard disk drive bracket, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 73.
2. Turn off the computer and all attached devices; then, disconnect all external
cables and power cords.
3. Remove the side cover (“Removing the side cover” on page 75)
4. Disconnect the signal and power cables from the hard disk drive that is installed
in the tray.
Note: To remove the hard disk drive from the tray, see “Removing a drive in
bay 5” on page 104.
5. Remove the two screws that fasten the top edge of the hard disk drive bracket
to the chassis (see Figure 29 on page 96).
