Rackmounting the SilkWorm 12000, 24000, and 48000 Directors

The SilkWorm 12000, 24000, and 48000 directors require that the rails be mounted in the Sun StorEdge 72-Inch Expansion Cabinet or Sun Rack 900/1000 equipment rack before installation of the directors.

Each SilkWorm 12000, 24000, and 48000 director comes with a rackmounting kit. The rackmounting kit is used for the Sun StorEdge 72-inch Expansion and Sun Rack 900/1000 equipment racks.

The SilkWorm 12000, 24000, and 48000 directors have a height of 14 RU (rack unit).

This chapter contains the following sections:


Installing the Rails for the Sun StorEdge 72-Inch Expansion Cabinet

Each SilkWorm 12000, 24000, and 48000 director comes with a rackmounting kit that contains two mounting rails and two sets of mounting rail brackets. The mounting rail bracket shown in FIGURE 4-1 is for the Sun StorEdge 72-Inch Expansion Cabinet.

One of two Sun StorEdge 72-Inch Expansion mounting assemblies, consisting of a mounting rail and bracket, is shown in FIGURE 4-2. When mounted, the director rests on the mounting rail ledge. FIGURE 4-2 Mounting Rail Assembly (One of Two) for the Cabinets

Figure showing the mounting rail assembly consisting of a mounting rail and bracket.


Install the two rail assemblies by performing the following steps for each.

1. Assemble the mounting rail and mounting rail bracket as shown in FIGURE 4-2.

Tighten the four 10-32 x 3/8-in. flat-head screws to a torque of 25 inch-pounds (28.8 cm-kgs). Make sure the screw heads are flush with the mounting rail.


FIGURE 4-3 Installing Two Screws Before Installing the Mounting Rail

Figure showing a Sun StorEdge 72-Inch Expansion Cabinet. The figure shows that the screws should be tightened only partially.


2. Partially install two of the 10-32 x 1/2-in. pan-head screws as shown in the cabinet vertical mounting surfaces. See FIGURE 4-3.

The top mounting rail lug and the top mounting rail bracket slot will slide onto these screws. The screws must be positioned so that the mounting rail will be in the lowest possible position in the cabinet. (The top screws will be in position 15.)


FIGURE 4-4 Positioning the Mounting Rail (One of Two) in the Cabinet

The figure shows the positioning of the mounting rail in the cabinet.


3. Place the mounting rail assembly as shown and slide the rail to fully engage the two screws in the mounting rail lug and the mounting rail bracket slot. See FIGURE 4-4.

The mounting rail flange attaches to the outside of the cabinet vertical mounting surface.

4. Install the remaining two 10-32 x 1/2-in. pan-head screws and tighten all four to a torque of 25 inch-pounds (28.8 cm-kgs).


FIGURE 4-5 Attaching the Mounting Rail Flange (One of Two) to the Cabinet

The figure shows the attachment of the mounting rail flange to the cabinet.


5. Secure the mounting rail flange in the front of the cabinet with six 10-32 x 1/2-in. pan-head screws.

Tighten the six 10-32 x 1/2-in. pan-head screws of each mounting rail flange to a torque of 25 inch-pounds (28.8 cm-kgs).


Installing the Rails for the Sun Rack 900/1000 Equipment Rack


Each SilkWorm 12000, 24000, and 48000 director comes with a rackmounting kit that contains two mounting rails and two sets of mounting rail brackets. The mounting rail bracket shown in FIGURE 4-6is for the Sun Rack 900/1000 equipment rack.FIGURE 4-6 Sun Rack 900/1000 Equipment Rack Mounting Rail Bracket

One of two Sun Rack 900/1000 equipment rack mounting assemblies, consisting of a mounting rail and bracket, is shown in FIGURE 4-7. When mounted the director rests on the mounting rail ledge.FIGURE 4-7 Mounting Rail Assembly (One of Two) for the Cabinets

The figure shows the equipment rack mounting assembly, consisting of a mounting rail and bracket.


Install the two rail assemblies by performing the following steps for each.

1. Assemble the mounting rail and mounting rail bracket as shown in FIGURE 4-7.

Tighten the four 10-32 x 3/8-in. flat-head screws to a torque of 25 inch-pounds (28.8 cm-kgs). Make sure the screw heads are flush with the mounting rail.


FIGURE 4-8 Positioning the Mounting Rail (One of Two) in the Cabinet

The figure shows the positioning of the mounting rail in the cabinet.


2. Attach the mounting rail assemblies to the rack using the six M6 screws in the back of the cabinet and the two 10-32 x 1/2-in. screws in the front of the cabinet. See FIGURE 4-8.

The mounting rail flange attaches to the outside of the cabinet vertical mounting surface. Align the bottom of the rail with the RU markings on the rack mounting rails. The mounting rail must be in the lowest possible position in the rack; the bottom of the rail will line up with RU marking 3.

3. Tighten the screws holding the front bracket to the rear bracket to a torque of 25 inch-pounds (28.8 cm-kgs).


Installing the SilkWorm 12000, 24000, and 48000 Directors


FIGURE 4-9 Removing the Front Door of the Director

The figure shows the removal of the Director's front door.


1. To remove the SilkWorm 12000, 24000 or 48000 director door, perform the following steps (see FIGURE 4-9):

a. Open the door and locate the spring hinge pins on the left side.

b. Press down on the lower spring hinge pin to release it, and press up on the upper spring hinge pin to release it.

It might be helpful to use a screwdriver to pry the hinge pins.

c. Pull the door out to remove it.


FIGURE 4-10 Placing the Director on the Hand Truck

The figure shows the placement of the Director on a hand truck.


2. Bring a hand truck up to the front of the director.

3. Use four people to pivot the director on its back edge and slide the hand truck forks under the director to support it. See FIGURE 4-10.

The figure shows securing the Director to the cabinet with screws.


6. Insert and tighten the ten 10-32 x 1/2-in. pan-head screws for the Sun StorEdge 72-Inch Expansion Cabinet or the ten M6 screws for the Sun Rack 900/1000 equipment rack to a torque of 25 inch-pounds (28.8 cm-kgs) on each side of the director mounting flange.



Note - Do not replace the director front door.



7. To ensure the proper cooling air flow, remove any filler panels on the front of the cabinet that are directly in front of the director.
