6.Some models have an optional hard disk drive mounting bracket 1 installed. When this bracket is installed, access to some of the CRUs or FRUs inside the chassis is restricted.

Note: There appears to be two drive bays in the bracket. However, due to thermal restrictions, only the bay 2 at the rear of the chassis can be used to install a hard disk drive.

See “Pivoting or removing the optional hard disk drive mounting bracket” on page 7.

To replace the computer cover, see “Completing the installation” on page 33.
