Attaching the fixed rails to the rack

If you have fixed rails, you might need to install them into the rack. Use this procedure to perform this task.

1. Select the appropriate EIA location unit number for the rails. Each EIA location contains three (3) holes for mounting hardware. For the purpose of these instructions, each EIA set of holes are identified as a, b, and c, from the top of each EIA unit to the bottom of each EIA unit.
2. Rotate the locking clamps downward at each end of both rails, to the open position.

   Note: The rails are marked with an L, to designate the left rail, and an R, to designate the right rail.
   Note: You might have to move the alignment pins in the fixed rails before installing the rails in the rack.
3. At the rack front, align the bottom of the right rail with the bottom hole (c) of the EIA unit selected, in both the front of the rack and the rear of the rack. The locator pins (A) fit into holes (b) and (c) of the EIA location directly above the lowest EIA unit used, on both the front and the rear of the rack.

4. Rotate the hinged rail latch upward to hold the rail in place against the front EIA support flange.
5. Repeat steps 1 through 5 for the left rail.
6. 
   Secure both rails to the front EIA support flange (B) by using two M5 x 16mm screws
7. At the rear of the rack, rotate the hinged rail latch upward to hold each rail in place against the rear EIA support flange.
