4. Fully tighten all clamping screws and middle slide locking screws.
5. Ensure the rear spacer clips (x4) are fitted tight to the edge of the rack post.
6. Slide the enclosure fully home on its rails.
7. Fasten the front of the enclosure using the enclosure fastening screws (x4) as shown in Figure 40
“Mounting the System into a Rack (left-hand rail only shown for clarity)” on page 39.
8. Fix the rear of the enclosure to the hold down bracket with the rear enclosure fixing screws (x2).
Note: Use the long or short hold down bracket depending on the distance from the rack post to the
enclosure hold down bay. Ensure that the sliding nut is at the rear of the bay prior to fitting the bracket to the
post, then slide the nut along the bay to enable the rear enclosure fastening screw to be fitted.
Notes: For rack depths where the rack posts are behind the enclosure hold down bays:
1. Swap the left and right hold down brackets.
2. Insert the long flange between the rack post and chassis side (see Figure 41 “Rear Enclosure Mounting”
on page 40).
3. The sliding nut head must always face away from the enclosure, whichever configuration is used.
