Before You Begin

Before setting up the rack, review the site requirements outlined in the Dell PowerEdge 24U Rack Site Planning Guide and complete any necessary preparations.

Safety Information

Carefully read the following safety information before you begin setting up the rack.

WARNING: Installing components in the rack without the front stabilizer installed could allow the rack to tip over and cause bodily injury under certain circumstances. Always install the stabilizer before installing components in the rack.

The stabilizer helps prevent the possibility of the rack tipping over when a component is installed and then pulled out of the rack to the fully extended position of the slide assemblies. For instructions on installing the stabilizer, refer to Installing the Stabilizer.

Recommended Tools

To set up the rack, you should have the following tools:

• A pallet jack or forklift to move the rack pallet
• Large and medium-sized Phillips screwdrivers

Setting Up the Rack

You must perform the following tasks to set up the rack:

1. Remove the rack from the pallet.
2. Position the rack.
3. Remove the doors.
4. Install the stabilizer.
5. Remove the side panels.

The sections that follow include instructions for performing these tasks.

Removing the Rack From the Pallet

Perform the following steps to remove the rack from the pallet.

1. Remove the top section from the packaging.
   The top section is secured by plastic clips.
2. Remove the Phillips screws from the boards at the base of the side pieces.
   Remove the two side pieces of the packaging.
3. Remove the two ramps from the storage space between the rack's casters.
4. Attach the ramps to the pallet using four screws.

Positioning the Rack

When positioning the rack, allow the following minimum clearances:

• For operation, leave at least 46 cm (1.5 ft) of clearance in front of the rack and 31 cm (1 ft) behind the rack to allow adequate airflow.
• For servicing, allow 61 cm (2 ft) of space behind the rack and 165 cm (65 inches) in front of the rack.

Removing the Doors From the Rack

Before installing the equipment in the rack, you may wish to remove the doors from the rack to improve access to the interior of the rack and to prevent damage to the doors. Perform the following steps to remove the doors.

1. Unlock and twist the handle clockwise (see Figure 2, Opening the Latch on the Door).
2. Open the front door.

3. Remove the front door as shown in Figure 3, Removing the Doors.
1. With the door open, lift out and fully retract all hinge pins.
2. Once all the hinge pins have been lifted out and retracted, lift the door out carefully.

If you wish to reverse the door so that the handle is on the other side, perform the following steps:

1. With the door open, lift out and fully retract all hinge pins.
2. Remove the hinges and door brackets from the door frame.
3. Replace the hinges and door brackets on the opposite side and switch the lock.

Installing the Stabilizer

For safety reasons, you should install the stabilizer on the rack by performing the following steps:

1. Extend the round leveling base at each corner of the rack.
   Turn each one clockwise until it contacts the floor, then lock it in place by tightening the locknut counterclockwise.  Ensure that the rack is level.
2. Position the stabilizer against the rack such that the its mounting holes are aligned with the corresponding holes in the rack (see Figure 4, Installing the Stabilizer).
3. Install the four hex-head screws to secure it to the rack.

Removing or Installing a Side Panel

You may need to remove a side panel from a rack to gain access to the rack's interior. Perform the following steps to remove a side panel from the rack.

1. Turn the key on the front of the side panel clockwise to unlock the side panel (see Figure 5, Removing the Side Panels). If the key turns hard, push it in slightly.
   The side panel will open out toward you.
2. Lift the side panel up and out of the bottom groove.
