Assembling the rack hardware

Procedure

  1. Determine how the device can be oriented in the rack so that the nonport side has access to intake air (cool). 
  2. Install clip or retainer nuts in the rack rail locations shown in the following figure. These nuts will secure the 10-32 screws that mount the rack kit's shelf and the device to the rack. For rails with round holes, use clip nuts. For rails with square holes, use retainer nuts. Note that the following figure shows relative positions for these nuts in the rack rails to mount the shelf and device. You may mount the shelf and device in 9U of rack space higher or lower in the rack than shown.

  3. Install the shelf saddle to the nonport side of the rack shown in the following figure. Install the saddle in the same vertical location as where the shelf installs on the port side of the rack. In using the previous figure as an example, if the shelf is installed in location 23 on the port side, install the saddle in location 23 on the nonport side. Ensure that the words "THIS SIDE UP" on the saddle face towards the port side of the rack (see the following figure). 

    Secure the saddle to the rack using four 10-32 screws with washers, two screws on each side of the saddle. Tighten the screws according to specifications under Torque Requirements.

    Note: For rails with round holes, use the clip nuts on the rails for securing 10-32 screws. For rails with square holes, use the retainer nuts. 
  4. Place the shelf (see the following figure) on the saddle then secure it to the rack rails using four 10-32 screws with washers shown in the following figure. Tighten the screws according to specifications under Torque Requirements.

    Note: For rails with round holes, use the clip nuts on the front rails for securing 10-32 screws. For rails with square holes, use the retainer nuts. 
  5. Install the air duct assembly (see the following figure) by inserting it down into the side-slot on the shelf. Ensure that the tabs of the duct align and engage with the slots in the shelf.

  6. Install the top rail inner bracket to the top rail assembly. 
    1. Determine the size of the top rail inner bracket that you will need to install on the top rail so that the top rail will fit on the inside of the rack rails. Remove the appropriate bracket from the accessory kit. Note that the accessory kit contains three sizes, depending on the depth of your equipment rack. 
    2. Secure the top rail inner bracket to the top rail assembly with two 6-32 screws. Tighten the screws according to specifications under Torque Requirements. 
  7. Install the top rail assembly. 
    1. Insert the top rail assembly (with the top rail inner bracket attached) down into the air duct assembly, and then secure the top rail assembly to the air duct assembly with two 6-32 screws, one screw on each side of the air duct assembly (see the following figure). 
    2. Secure the top rail assembly to the rack. 

       For rails with round holes, use two 10-32 screws with washers on each end of the top rail assembly. Tighten the screws according to specifications under Torque Requirements. 

       For rails with square holes, use the two standard 10-32 screws with blue Loctite on the threads and alignment washers on each end of the top rail assembly. Tighten the screws according to specifications under Torque Requirements.
