e. Repeat these steps for the other rail.
Step 3. Place the back of the enclosure (the end with the connectors) on the rails.
Attention: A fully loaded enclosure weighs approximately 65 lb (29 kg). Two persons are required
to safely move the enclosure.
Step 4. Carefully slide the enclosure all the way onto the rails.
Note: If applicable, you might need to remove the shelf end caps or the system bezel to secure the
enclosure to the rack post; if so, you need to replace the end caps or bezel when you are done.
Attention:
• You might need to adjust the rails to ensure that the enclosure slides all the way onto the rails.
• Two M5 screws are used to secure the enclosure to the back of the rails. You might need to
remove the M5 screws on the inner rail to ensure that the enclosure slides all the way back.
Attention: Do not place additional equipment on the rails after you finish installing the enclosure.
The rails are not designed to bear additional weight.
Step 5. Secure the enclosure to the front of the rack and rails by inserting two round-head M5 screws
through the mounting brackets (pre-installed on either side of the front of the enclosure), the holes
on the rack, and the holes on the front of rails.
