Installing the Disk Array Enclosures into a Rack
This section describes how to install the disk array enclosures into a rack.
Installing Cage Nuts
1. Locate the cage nuts from the rack mounting hardware kit contents.
2. Start at rack positions 3 and 4 when installing full arrays. Leave rack space for future expansion
for any partial array being installed. See
“Mounting the Disk Array Enclosures into the
Rack” (page 25) for the placement of the enclosures.
3. Install a cage nut in the middle hole of each position on the front vertical posts for a total of
two on each side.
4. On the left front post, between the two cage nuts just installed, install a cage nut in the bottom
hole.
5. On the right front post, between the two cage nuts just installed, install a cage nut in the top
hole.
6. Repeat this procedure on the front vertical posts for each 2U enclosure to be installed.
