Figure 4.1 Removing rack from shipping pallet
ITEM DESCRIPTION
1 Anchor bracket
2 Bolt-hole for securing anchor bracket to rack (2 typical)
3 Lag-bolt holes for securing anchor bracket to pallet and/or floor
4.4 Equipment Layout, Repositioning, Removal and Installation
To keep the unit’s center of gravity as low as possible, install equipment from the bottom up, starting with
the heavier units. Leave any unused space at the top of the rack.
CAUTION: After equipment is installed, the DCF Optimized Rack System may have a high center of
gravity. Avoid tipping the unit when it is being moved.
4.4.1 Installing the Edge Guard
1. Press edge guard to the top-cover cut outs by pressing along the edge of the cut out opening
as shown in the following figure.
Vertiv | DCF Installer/User Guide | 14

2. Trim excess edge guard with a pair of scissors after the edge guard after completely applied
around the opening.
3. Repeat steps 1 and 2 for remaining cut outs.
Figure 4.2 Applying the edge guard
4.4.2 Positioning and Attaching Front-andRear-Mount19-in.EIARails
Front- and rear-mount, 19-in., EIA rails are installed in 600-mm wide racks at the factory at 29.13in.
(740mm). They attach to the cabinet frame at the top and bottom, in the center to the support member
using M6x12 Torx-head screw into a rail-adjustment bracket.
In 800-mm wide racks, 19-in. EIA rails are attached using node brackets. The node brackets attach to the
top and bottom of the DCF frame and in the center to the support member. The EIA rails move as a unit if
they need to be repositioned.
To position the EIA rails on 600-mm cabinets:
1. Determine the installation location of the EIA rails.
2. Loosen the M6x12 screws in the rail-adjustment brackets, securing the 19" EIA rails to the frame
member as shown in the following figure.
NOTE: Rails in both the 600- and 800-mm wide racks are attached at the top, center and bottom.
3. Slide the rail-adjustment brackets up or down, depending on their orientation in the rack.
4. Slide the EIA rail to the desired position, making sure to keep it square. The frame member and
support have small holes spaced on 6.35-mm centers to help properly position the rails.
NOTE: The front and rear 19-in. EIA rails must be kept at a 90-degree angle to the upper and lower
frame members. The left- and right-front vertical rails must be the same distance from the front of the
rack. The left- and right-rear vertical rails must be the same distance from the rear of the rack. If these
conditions are not met, equipment and optional features will be difficult to install.
Vertiv | DCF Installer/User Guide | 15

5. Hold the rail in position, then and the M6x12 screws into the rail-adjustment brackets.
6. Repeat steps 2 to 5 for the corresponding rail.

2. At the top, bottom, and center-support member, loosen the 2 screws that secure the node-
adjustment brackets to the bottom frame member, then slide the bracket down.
Vertiv | DCF Installer/User Guide | 16

3. Slide the rails to their new location.
NOTE: The rails will bind if they are not kept at a right angle to the frame.
4. Tighten all hardware.

4.4.3 Removing and Reversing Doors
DCF doors are removable for convenience when installing or maintaining equipment. The front door is also
reversible, so the single door may be opened in a more convenient direction if the rack is near a wall or
other equipment.
To remove a door:
Doors are supported by two hinges and held in place by gravity. They can be lifted off and reinstalled
without tools.
NOTE: Doors are easier to remove if they are open at a 90° angle to the DCF cabinet.
To reverse the front door:
NOTE: The door handle cannot be reversed.
1. Lift the door off the DCF, the loosen and remove screws from both the top and bottom hinges,
shown in the following figure.
2. Remove the hinges and place them on the opposite side of the frame in the slots provided.
3. Reinsert and tighten the screws.
4. Remove the hardware from the door catch and install the catch on the opposite side of the
frame.
5. Flip the door.
The hinge pin assemblies are now at the bottom of the hinge-pin attachment point.
6. Remove the hardware, flip the hinge pin and reinsert it in the hinge-pin attachment point.
Vertiv | DCF Installer/User Guide | 17

7. Reattach the hinge pin with hardware.
8. Hang the door on the newly positioned hinges.

4.4.4 Removing and Replacing Side Panels
The DCF uses dual split-side panels fashioned from sheet metal. The lower panel hangs on a frame
member and the upper panel hangs on the rack frame. Each panel is secured with a lock making the
panels simple to remove and replace when installing equipment and performing maintenance .
To remove a side panel:
1. To remove a panel, insert the key in the side-panel lock and turn clockwise to unlock it.
2. Lift the panel up and away from the rack, and set it aside.
3. Repeat steps or other panels being removed.
To replace a side panel:
1. Insert the bottom of the panel into the cut-outs.
2. Move the top of the panel toward the rack.
3. Turn the key counterclockwise to lock the panel in place.
4. Repeat steps for other panels being replaced.

4.5 Mounting Power Distribution Units
Power distribution units may be mounted on the rails or attached to mounting brackets in the DCF. The
following are the PDU options:
•42U full-height PDU/cable-management mounting brackets (4-in.W) (Part#546076G1L)
•48U full=height PDU/cable-management mounting brackets (4-in.W) (Part#546077G1L)
4.5.1 Installing a Full-height PDU/Cable-Management Bracket
The top and bottom of the 4-in. wide brackets are identical for use on either side of the cabinet.
To install a full-height bracket:
1. Position the full-height bracket for installation with the inside bottom flange of the PDU resting
on the flange of the frame member at the top and bottom. See the flange in the following figure.
2. Hold the PDU bracket in place, then insert and tighten the screws.
Figure 4.6 Full-height bracket end
ITEM DESCRIPTION
1 Bracket flange
2 Bracket clips
To reposition a full-height bracket:
1. Loosen the screws in the top and bottom PDU hanging bracket.
2. Slide the bracket along the frame member to the desired location and tighten the screws.
To remove a full-height bracket:
1. Loosen the screws in the top and bottom PDU hanging bracket.

4.6 Baying the DCF Cabinets
Two or more DCF cabinets of the same height can be bayed with the supplied baying brackets. The
brackets have three holes:
•The single hole connects to the cabinet
•The outer hole centers the cabinets at 24in.(609.6mm)
•The center hole puts the cabinets on metric centers.
Connecting the racks is easier if the are in their final installation position before baying.
