Installation Workflow

  1. Attach the appliance(s) to the shelf.

  2. Attach the shelf to the rack.

Appliance Orientation:

You can install the 3920 appliance on the shelf with either the front or rear panel facing the front of the rack.

The 3950 appliance must be installed on the shelf with the front panel (appliance ports) facing the front of the rack.

Installation Types:

  • Single

  • Side by side

Workflow:

  1. Identify the correct position of the appliance on the shelf.

  2. Install the appliance and power adapter.

  3. Attach the cables and power adapter cables to the appliance.

  4. Install the shelf in the rack.

Appliance Positions on the Shelf

The screw holes on the shelf are marked with letters for proper positioning of the appliance. Make sure to use the correct screw holes for your appliance model and setup.

Single Appliance Installation

Note - You must install a single appliance in the middle of the shelf, not on the side.

  1. Place the shelf on a flat surface.

  2. Identify the location and holes to use for your appliance (see Appliance Positions on the Shelf).

  3. Attach the appliance to the shelf using two M3x5 screws and two rack mount washers:

    1. Lift the shelf from the flat surface and insert the screw from underneath through the hole next to the applicable letter.

    2. Place the washer on top of the screw, with the wider part facing up.

    3. Place the spacer tool so that its indentation is fixed against the screw on the top side of the shelf.

    4. Turn the washer a few times until it reaches the spacer tool and remove the tool so there is a gap. The spacer tool prevents you from twisting the washer too far.

  4. If there are rubber feet installed on the bottom of the appliance, remove them.

  5. Align the holes on the bottom of the appliance with the screw / washer assembly.

  6. Place the appliance on top of the screw / washer assembly and slide it forward until it settles into position.

  7. To secure the appliance, use a screwdriver (not included in the kit) to tighten the screws on the bottom of the shelf. After you fasten the screws, the appliance is locked to the shelf.

Side by Side Appliance Installation

The steps for a side-by-side installation are the same as for a single appliance. However, in a side-by-side setup, you need to place one appliance on each side of the shelf.

  1. Place the shelf on a flat surface.

  2. Identify the locations and holes to use for your appliances (see Appliance Positions on the Shelf).

  3. Attach an appliance to one side the shelf using two M3x5 screws and two rack mount washers:

    1. Lift the shelf from the flat surface and insert the screw from underneath through the hole next to the applicable letter.

    2. Place the washer on top of the screw, with the wider part facing up.

    3. Place the spacer tool so that its indentation is fixed against the screw on the top side of the shelf.

    4. Turn the washer a few times until it reaches the spacer tool and remove the tool so there is a gap. The spacer tool prevents you from twisting the washer too far.

  4. If there are rubber feet installed on the bottom of the appliance, remove them.

  5. Align the holes on the bottom of the appliance with the screw / washer assembly.

  6. Place the appliance on top of the screw / washer and slide it forward until it settles into position. See the following diagrams.

  7. Repeat steps 3 - 6 for the second appliance.

  8. To secure the appliances, use a screwdriver (not included in the kit) to tighten the screws on the bottom of the shelf. After you fasten the screws, the appliances are locked to the shelf.
