Assembling the Rack Hardware

Attach the left and right rack mount shelf brackets to the rack rails.

  1. Locate the shelf brackets in the device.
  2. Locate and loosen the screws on the adjustable ends of the brackets to allow for adjustment to rack depth.
    Figure 1. Left and Right Shelf Brackets Installed on Rails
     1  Left rack mount shelf bracket
     2  Right rack mount shelf bracket
     3  1/4-20 x 1/2 in. (1.27 cm) panhead Phillips screw with lock washer – for rails with round holes (four on each end of each bracket, 16 total)
     4  3/8 in. (0.953 cm) alignment washer – for rails with square holes (four on each end of each bracket, 16 total)
     5  1/4-20 x 1/2 in. (1.27 cm) panhead Phillips screw with thread locker – for rails with square holes (four on each end of each bracket, 16 total)
     6  Adjustable ends of shelf brackets
     7  Intake air direction
     8  Exhaust air direction
    CAUTION:
    Use the screws specified in the procedure. Using longer screws can damage the device.
  3. Position the shelf brackets with the adjustable ends on the intake air aisle side of the rack (see the previous figure).
      • For rails with round holes, position the left and right rack mount shelf brackets and attach them to the rack rails.

    Use eight screws with lock washers per bracket (four on each end). Tighten the screws to a torque of 92 cm-kg (80 in.-lb.).

      • For rails with square holes, position the left and right rack mount shelf brackets and attach them to the rack rails.

    Use eight screws and alignment washers per bracket (four on each end). Tighten the screws to a torque of 92 cm-kg (80 in.-lb).

    Figure 2. Nut and Screw Locations for Mounting the Device

     1  10-32 clip nuts (for round holes)
     2  Rail
     3  10-32 retainer nut (for square holes)
     4  Rail
     5  Top screws in shelf bracket
     6  Bottom screws in shelf bracket
     7  Left rack mount shelf bracket
     8  Right rack mount shelf bracket
     9  Hole 1
    Note: Standard EIA rails have holes in sets of three; spaces between the holes are 1.58 cm, 1.58 cm, and 1.27 cm (5/8 in., 5/8 in., and 1/2 in).
  4. Tighten the adjusting screws on the sliding portion of the rack mount shelf brackets to a torque of 37 cm-kg (32 in.-lb).
  5. Attach the clip nuts (for rails with round holes) or retainer nuts (for rails with square holes) to the vertical rails on the exhaust aisle side of the rack (see the previous figure). These clip nuts are used for securing the port side of the device to the rack rails using 10-32 x 5/8 inch screws. Use three clips on each rail. Place the clips in optimum locations for securing the device to the rails.
