1 Introduction
This document describes the installation of the StorageWorks™ SW500 and
SW800 cabinet metric shelf bracket kit. Procedures for horizontal and vertical
front and rear shelf bracket installation are presented. There are two types of
shelf brackets: shelf brackets with screw mounts and shelf brackets with tab
mounts.

2 General Description
Note
In the following descriptions and procedures, the terms front and rear
are references to locations in the cabinet. The terms inner and outer are
references to positions on the shelf brackets.

Each metric bracket set consists of a pair of shelf brackets, stop brackets, and
locking brackets. See Figure 2 for examples of these components.
There are two types of shelf brackets: shelf brackets with screw mounts and shelf
brackets with tab mounts.
The stop brackets are attached to the inner portion of the shelf brackets to
position the shelf within the brackets. The locking brackets fix the shelf in place.
Various combinations of stop positions and locking bracket sizes are necessary to
situate a particular shelf for proper clearance from the cabinet doors.
The shelf bracket and stop bracket parts are used to mount all types of
StorageWorks shelves in all locations. The bracket set for shelves mounted
in various positions in the cabinet differs only in that the locking brackets are
unique parts sized for specific cabinet positions.

3 Shelf Bracket Types
SW500 and SW800 cabinets can come preconfigured with screw-mounted or
tab-mounted shelf brackets. Cabinets that have been field modified can contain
both types of shelf brackets. See the following descriptions to determine your
cabinet configuration.

3.1 Screw-Mounted Shelf Brackets
A typical screw-mounted bracket set is shown in Figures 2 and 8. The shelf
bracket used in this set can be identified by the two screw holes between the
front of the bracket and the stop bracket screw holes.
In the horizontal position, the screw-mounted brackets are attached to the
vertical cabinet rails with six screws. In the vertical position, the screw-mounted
brackets are attached to the horizontal cabinet bracket with six screws.

3.2 Tab-Mounted Shelf Brackets
A typical tab-mounted bracket set is shown in Figures 4 and 10. The shelf
bracket used in this set can be identified by the formed metal slot with four
mounting tabs between the front of the bracket and the stop bracket screw holes.
In the horizontal position, the tab-mounted brackets are attached to the vertical
cabinet rails with four M5 KEP nuts and four mounting tabs. In the vertical
position, the tab-mounted brackets are attached to the horizontal cabinet bracket
with four M5 KEP nuts and four mounting tabs.

3.3 Horizontal Cabinet Brackets on the Vertical Slots
Before installing a shelf bracket kit in the vertical position in a SW800 cabinet,
determine the type of horizontal cabinet bracket. The type of horizontal cabinet
bracket determines which type of shelf bracket kit is compatible.
There are two types of horizontal cabinet brackets; a set of two narrow brackets
or a one-piece bracket:
•

Type 1: Two narrow brackets, one attached to the front vertical cabinet rails
and the other attached to the interior vertical rails. The rear bracket has two
holes with captive floating nuts. Type 1 horizontal cabinet brackets accept
only screw-mounted shelf brackets. To install tab-mounted shelf brackets in
a cabinet with type 1 horizontal cabinet brackets, see Section 8.2 for cabinet
configuration differences and Section 8.3 for cabinet modification procedures.

•

Type 2: A one-piece bracket that attaches to the vertical cabinet rails and has
four holes at the rear where the shelf bracket’s mounting tabs are inserted.
The type 2 horizontal cabinet bracket accepts either the screw-mounted or
tab-mounted brackets.

4 Shelf Bracket Kit Configurations
Before mounting the metric shelf bracket kit, check the contents of the bracket
kit against the parts list. See Table 1 for the SW500 and SW800 Metric Shelf
Screw-Mounted Bracket Kit Parts List. See Table 2 for the SW500 and SW800
Metric Shelf Tab-Mounted Bracket Kit Parts List.

5 Cabinet Preparation and Shutdown
Before mounting the metric shelf bracket kit, perform the following actions:
WARNING
While working in the cabinet interior, ac power must be removed from
cabinet components. Failure to do so can result in personnel injury as a
result of electric shock.

1. If the cabinet is installed and operating, spin down all disk drives and halt
all tape drives in the cabinet.
2. Remove ac power from cabinet components by switching the circuit breaker
on the front panel of the cabinet’s power controllers or cable distribution units
to the OFF or
position.
After you have made sure that all the parts are present and that ac power has
been removed from the cabinet components, you may begin shelf installation.

6 Accessing the Cabinet Rack Space
In maximum configurations when access to the interior of the cabinet is limited,
external cabinet panels might need to be removed before shelves can be installed
or reconfigured. Section 6.1 presents procedures for removing exterior cabinet
panels.
The front and rear cabinet doors are held closed by door locks mounted on
the smooth vertical panel of each door. The locks are released by turning
counterclockwise with a 5/32-inch hex wrench.

6.1 Removing the Exterior Cabinet Panels
As shown in Figure 1, there are three side panel hanger clips on each side of the
cabinet. A matching set of hanger clips are attached to each side panel. Remove
the side panels as follows:

1. Move the cabinet away from adjacent enclosures as necessary.
2. Loosen the top cover by pushing up on its front and rear edges until it snaps
free of its fasteners.
WARNING
The top cover is heavy and awkward to lift. Removing it requires two
people. Failure to use sufficient personnel can result in personnel injury
or equipment damage.

3. Using two people, lift the top cover from the cabinet and set it aside.
4. Remove the bolts attaching the side panels to the top side rails of the cabinet.
5. Grasp a panel along its front and rear edges and lift up until the hanger clips
disengage. Lift the panel away from the cabinet.
6. Repeat the previous step to remove the other panel.
7. Install the horizontal or vertical shelf brackets using the following procedures.

7 Horizontal Shelf Installation
There are two types of horizontal shelf bracket installations: those using shelf
brackets with screw mounts, and those using shelf brackets with tab mounts.
See Section 7.1 for installations using shelf brackets with screw mounts. See
Section 7.2 for installations using shelf brackets with tab mounts and mounting
studs. Either the screw-mounted bracket set or tab-mounted bracket set can be
used in horizontal shelf installations in any SW500 and SW800 cabinet.

7.1 Installing Horizontal Shelf Brackets with Screw Mounts
Shelf bracket installations for front and rear horizontal shelves using screw
mounts are shown in Figures 2 and 3. Using the illustrations as a guide, install
horizontal shelf brackets as follows:
WARNING
Cabinet rail edges can be sharp and can slice or abrade skin or cable
insulation.

Note
Two small ESD grounding posts are provided with the cabinet. One is
located on a front vertical cabinet rail, and one on a rear vertical cabinet
rail. Should an ESD grounding post interfere with the installation of a
shelf, move the post out of the way to any free hole on the cabinet.

1. Turn the cabinet power off as described in Section 5.
2. Determine the correct shelf mounting locations and corresponding cabinet rail
mounting holes for the shelf bracket.
3. Position the shelf bracket at the correct mounting holes just behind the outer
flange of the vertical cabinet rail.

4. Using the shelf bracket as a template, mark the two U-nut mounting holes on
the inner flange of the cabinet rail.
5. Remove the shelf bracket and install two U-nuts along the inner flange of the
cabinet rail at the holes marked in step 4.
6. Position and fasten the shelf bracket to the outer flange of the cabinet rail
with two screws.
7. Fasten the bracket to the U-nuts with two screws.
8. Using Table 3, determine the correct stop bracket position for the shelf type
being installed.

9. Insert the tab on the stop bracket into the slot at the correct stop position on
the shelf bracket. Fasten the stop bracket to the shelf bracket.
10. Repeat steps 2 through 9 to mount the companion shelf bracket on the
opposite cabinet rail. To be sure of proper alignment of the brackets, use care
to mount the bracket to the correct rail mounting holes.
11. With the power supply end of the shelf to the left and the blowers facing
the cabinet, slide the shelf into the shelf brackets until it contacts the inner
stop brackets. The shelf should slide smoothly into the brackets. If it binds,
remove it and check the alignment of the shelf brackets. The shelf bracket
mounting screws might need to be loosened slightly to allow the brackets to
align with the shelf. Tighten the screws when the shelf brackets are properly
aligned.
12. Using Table 4, verify that you have the correct locking bracket part number
for the shelf type and position (front or rear) being installed.

8 Vertical Shelf Installation
There are two types of vertical shelf bracket installations: those using shelf
brackets with screw-mounts, and those using shelf brackets with tab-mounts.
When installing shelf brackets in the vertical position the shelf brackets used are
determined by the horizontal cabinet bracket that was factory installed.

8.1 Horizontal Cabinet Bracket Types
There are two types of horizontal cabinet brackets: a set of two narrow brackets
or a one piece bracket:
•

Type 1: A two-piece bracket, one attached to the front vertical cabinet rails
and the other attached to the interior vertical rails (see Figure 6). The rear
bracket has two holes with captive floating nuts. Type 1 horizontal cabinet
brackets accept only screw-mounted shelf brackets. To install tab-mounted
shelf brackets in a cabinet with Type 1 horizontal cabinet brackets see
Section 8.2 for cabinet configuration differences and Section 8.3 for cabinet
modification procedures.

•

Type 2: A one-piece bracket that attaches to the vertical cabinet rails and has
four holes at the rear where the shelf bracket’s mounting tabs are inserted
(see Figure 7). The type 2 horizontal cabinet bracket accepts either the
screw-mounted or tab-mounted brackets.

8.5 Installing Vertical Shelves with Tab Mounts
Shelf bracket installations for front and rear vertical shelves using tab mount
brackets are shown in Figures 10 and 11. Using the illustrations as a guide,
install the vertical shelf brackets as follows:
WARNING
Cabinet rail edges can be sharp and can slice or abrade skin or cable
insulation.

1. Turn the cabinet power off as described in Section 5.
2. Determine the correct vertical shelf location for the shelf bracket.
3. Position the shelf bracket at the correct mounting holes just behind the outer
flange of the horizontal cabinet bracket.
4. Align the bracket mounting studs and mounting tabs with the appropriate
holes in the horizontal cabinet bracket and seat the studs and tabs in the
holes.
5. Fasten the bracket to the horizontal cabinet bracket by installing KEP nuts
on the left-most and right-most bracket mounting studs. Do not install nuts
on the two middle studs at this time.
6. Using Table 10, determine the correct stop bracket position for the shelf type
being installed.

7. Insert the tab on the stop bracket into the slot at the correct stop position on
the shelf bracket. Fasten the stop bracket to the shelf bracket.
8. Repeat steps 2 through 7 to mount the companion shelf bracket on the
horizontal cabinet bracket above the one just installed.
9. With the power supply end of the shelf at the top and the blowers facing
the cabinet, slide the shelf into the shelf brackets until it contacts the stop
brackets. The shelf should slide smoothly into the shelf brackets. If it
binds, remove it and check the alignment of the shelf brackets. The bracket
mounting nuts might need to be loosened slightly to allow the brackets to
align with the shelf. Tighten the nuts when the brackets are properly aligned.

10. Using Table 11, verify that you have the correct locking bracket part number
for the shelf type and position (front or rear) being installed.

11. Once the shelf is positioned within the shelf brackets, install the locking
brackets with KEP nuts on the two middle mounting studs. Push each
locking bracket against the shelf to seat it before tightening the nuts.

9 Installing Exterior Cabinet Panels
Once the cabinet rack space is configured as desired, the exterior cabinet panels
may be installed. Refer to Figure 1 and install the exterior cabinet panels as
follows:
1. Position a side panel against the cabinet with the lip above the upper hanger
clips just over the upper edge of the side of the cabinet.
2. Make sure that the entire surface of the side panel rests firmly against the
side of the cabinet.
3. Allow the panel to slide downward, catching the three hanger clips as it
moves.
4. Install the side panel bolts into the side panel through the holes in the top
side rails of the cabinet.
5. Repeat steps 1 through 4 to install the other side panel.
6. Locate the four inset nylon snap fasteners on the top cabinet rails.
WARNING
The top cover is heavy and awkward to lift. Installing it requires two
people. Failure to use sufficient personnel can result in personnel injury
or equipment damage.

7. Position the top cover over the cabinet. Position the cover as shown in
Figure 1 such that the end of the panel with the shorter overhang is oriented
toward the front of the cabinet.
8. Align the pins on the underside of the top cover with the inset nylon fasteners
on the top cabinet rails.
WARNING
Be careful not to catch your fingers between the cabinet and the top panel
when snapping the panel to the cabinet.

9. Lower the cover onto the cabinet and press it down, making sure that the
pins snap into the top panel fasteners.
10. If the cabinet was moved to access the side panels, place it in its original
position.
