Follow these steps to install the enclosure on the rails in the cabinet.
Place the disk enclosure that contains specially-marked "storage system
software" disks 0-4 as close as possible to the CX3-series storage processor
enclosure. In most cases, install it directly above the standby power supply,
as shown in Figure 2 on page
directly to the SPE3 and SPS.
The disk modules in slots 0 through 4 of the first DAE3P in your system
provide mirrored boot and recovery capability, and are preconfigured
according to their slot assignment before shipment. Do not move a module in
slots 0 through 4 from its assigned slot to another slot. Remove one of these
modules only if it has failed and you are replacing it with a new module.
1. With help from another person, lift the enclosure and, from the front
of the cabinet, slide the enclosure onto the rails as shown in
Figure 14.

Sliding an enclosure onto the mounting rails
When the enclosure slides to the back of the cabinet, the two
notches in the rear of the enclosure insert into the rear tabs
approximately 14 inches from the front of each rail. The tabs
secure and support the rear of the enclosure. See
page 25.
Note: If the chassis does not slide all the way into the cabinet, you may
need to further loosen the screws that hold the rear of the rails in place,
then adjust the rails to allow the tabs to fit into the notches.
3. You will connect that first DAE3 (enclosure 0)
