Installing the support rails for an optional 5U92 disk enclosure

You must install the support rails before you can install a 5U92 disk enclosure in a rack.
Procedure
1. Locate the hardware that is used to install the rails, including the M4xL6 and M5xL13 screws.
Set the hardware, which is shown in Figure 11 on page 22, aside for use later in the installation
process.

2. Select an available 5U92 space in your rack to install the expansion enclosure.Refer to the rack
configuration planning worksheet that is completed by the customer, and select the 5U92 space for
the IBM Cloud Object Storage System
Important notes:
• When you select a rack location, ensure that the enclosure and its parts are easily accessible. Allow
enough space for the lid to be easily removed and for internal components, such as drives and
secondary expansion modules, to be serviced.
• When all components and drives are installed, the disk enclosure is heavy. Install the support rails
and enclosure at the lowest available position. Do not install the rails and enclosure above position
U25 in the rack.
3. Remove the inner member of the rail. Push the tab (
shown in Figure 12 on page 22.
