3. Changing the Cabinet's Configuration

3.1 Casters and Leveling Legs

CAUTION: To install casters or levelers, you must tip the enclosure onto its side. The enclosure is very heavy, so you may need several people to lay it on its side. Do not lay the enclosure on its front or back. This may damage the door and hinges.

HINT: Removing the doors and side panels before tipping will help reduce the enclosure's weight and help prevent damage to the side panel locks.

Technical line drawing of a mechanical assembly with mounting brackets and wheels (no text or symbols)

Figure 3-1. Casters and levelers.

Caster Mounting:

1. Tip the enclosure and lay it onto its side.
2. Place a caster assembly over the four threaded studs located in one of the recessed areas in the bottom of the enclosure.
3. Thread one 516 -18 hex nut onto each of the four studs and tighten with a 12 " socket or nut driver.
4. Repeat Steps 2 and 3 for the three remaining casters.

Adjustable Leveler Mounting:

1. Tip the enclosure and lay it onto its side.
2. Place a leveling leg into one of the four 12 "-13 threaded holes found at the corners of the enclosure.
3. Using a 34 " open-end wrench, tighten the levelers to the desired position.
4. Repeat Steps 2 and 3 for the remaining levelers.

3.2 Door Handle Operation

The Elite enclosure ships with its front and rear doors unlocked, and includes two keys.

3.3 Removing or Changing the Doors

3.3.1 Removing or Installing a Door

Open the door beyond 90°, then grasp the door with both hands and carefully lift it upward. When the door is free of all three hinge pins, pull the door away from the enclosure. To attach the door, align all three door hinges to their respective hinge pins on the enclosure and slowly slide the door down until seated.

Open door beyond 90 degrees then lift off straight up

Figure 3-4. Attaching a door.

3.3.2 Reversing a Door

The front and rear doors are installed with a right-hand hinge as standard from Black Box. Removing the hinges enables you to reverse the door by flipping them over and reinstalling the hinges using the universal mounting holes. All the enclosure frames and doors can be hinged right- or left-hand. The handle can be reversed along with the hinging. See Figure 3-5.

Figure 3-5. Reversing a door.

3.4 Removing or Installing a Side Panel

The side panels connect to the enclosure frame with two quick-release latches and a keyed lock. To remove the side panel, unlock the panel and press the quick-release latches down and release them. Then tilt the top of the side panel out slightly and lift the side panel up a couple of inches until it is free. To install the side panel, reverse the process. Make sure the slots on the side panel engage with the two tabs at the bottom of the frame.

Tilt and lift the side panel Press quick release latches down and release

Figure 3-6. Removing or installing a side panel (30" wide cabinet shown).

3.5 Top Panel and Mounting Options

The top panel of the enclosure is installed at Black Box. To remove the top panel, remove the four #10-32 x 1" large Phillips pan-head screws. Then simply lift the top panel up and off. There are six versions of top panels (solid, perforated, 1-fan, 2-fan, 3-fan, 6-fan).

The top panel provides 12U of standard rackmount space that you can customize. When one of the standard top panels is not used, you can use this area to mount patch panels, additional cable management, PDUs, 19" fan panels, and other lightweight items.

3.6 Adjusting the Rails

Mounting Rails

The vertical mounting rails are installed with all standard frames. You can configure the 30" wide enclosure to 23" EIA mounting with an optional bracket set. Extra sets of both square hole rails (M6) and tapped #10-32 rails are available as accessories. (See page 15).
