Installing the system on the rail assembly

You might need to install the system on the rail assembly. Use the procedure in this section to perform this task.

1. Fully extend both rails.
2. Using two people, lift the system unit, and position the system on the extended rails.
   CAUTION:
   This unit weighs between 17.7 kg (39 pounds) and 21.7 kg (48 pounds). Two people are required to safely move it.
3. Align the slots on the system unit chassis with the tabs A on the rails.
4. Lower the system unit so that the tabs slide into the slots on the chassis B. The system unit will lock into place.
5. Simultaneously release the blue safety latches C located near the front of the rail assembly, and push the system unit into the rack.
   
   Figure 1. Lowering the system onto the rails.
6. Slide the system unit into and out of the rack two or three times to align the system unit to the rails. The system unit should glide on the rails.
   Attention: Do not, under any circumstances, force the rails. If the system drawer does not glide freely into the rack, completely remove the drawer from the outer rails. After the drawer is clear of the outer rails, reposition the system, then reinsert the inner rails. Repeat this process until the system drawer glides freely into the rack
7. Push the system unit into the rack.

   After the system rails are installed, do not extend them past their safety latches. The safety latches prevent the rails from overextending and separating, thereby preventing the system unit from being pulled out too far and being dropped.
