Installing the support rails
You must install the support rails before you can install a 5U expansion 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 22 on page 40, aside for use later in the installation
process.

2. Select an available 5U space in your rack to install the expansion enclosure.
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.
