You must install the support rails before you can install a Model 092 expansion enclosure in a rack.

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.
• When all components and drives are installed, the expansion enclosure is heavy. Install the support
rails and enclosure at the lowest available position. Do not install the rails and the enclosure in the
32U position and above in the rack when you relocate the rack. After the rack is installed, you can
install devices in the 32U position and above.
