  1. Some models have an optional hard 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 drive. See "Pivoting or removing the optional hard drive mounting bracket".
