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.

5U92 disk enclosure, as shown in Figure 16 on page 23.
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 ( a ) and slide the middle rail member back, as
shown in Figure 12 on page 22.
