33.4 How to Add Rear Rack Ears to HPU

The following instructions describe how to assemble and attach the rear rack mounting assembly kit (sold separately) to the HPU:

  1. Attach the rail adapters to the rear chasis brackets using the 10-32 x .5 screws from the kit. Note: the rack adapters have 4 screw holes to account for different rack depths but only two screws are required for secure assembly.

  2. Attach the rear chasis brackets to the rear of the HPU using two 6-32 x .25 screws per bracket.

  3. Use the remaining 10-32 x .5 screws to secure the HPU to the rear rails to a 19" rack enclosure.
