Installing the J4200/J4400 Array Rail Kit

This document describes how to install the J4200/J4400 Array Rail Kits.

Note - The instructions and graphical illustrations used throughout this guide are specific to the J4200 Rail Kit installation, with additional information unique to the J4400 Rail Kit where appropriate. Although the illustrations used throughout this document are specific to the J4200 Rail Kit, the J4400 Rail Kit is functionally the same mechanism, but with wider vertical flanges that require additional screws as noted.

Prepare the Cabinet

You can install the rail kit in any of the following cabinets:

Sun Rack 900/1000 cabinet

Sun Fire cabinet

Sun StorEdge Expansion cabinet

Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back depth between vertical cabinet rails of 61 cm to 91 cm (24 in. to 36 in.). The cabinet can have threaded or unthreaded cabinet rails.

1. Select the cabinet in which you will be installing the array. Be sure the cabinet is installed as described in the cabinet installation instructions.

2. Stabilize the cabinet as described in the cabinet documentation.

3. If the cabinet has casters, make sure the casters are locked to prevent the cabinet from rolling.

4. Position the data host next to the cabinet in which the array will be installed.

Installing the Rail Kit in a Sun Rack 900/1000 Cabinet

Use the following procedure for the Sun Rack 900/1000 cabinet.

Prerequisites

Complete the following before you install the rail kit:

Check the cabinet installation as described in Prepare the Cabinet.

Unpack the left and right adjustable rails.

Obtain a #2 Phillips screwdriver (minimum 4-inch length recommended).

Gather the required mounting hardware for the cabinet (see TABLE 3 or TABLE 4).

TABLE 3 Sun Rack 900/1000 Cabinet Mounting Hardware (J4200 Array)
Quantity	Description	Purpose
4	M6 rail plate brackets	Attaches to a threaded EIA (vertical) cabinet rails
4	M6 screws	Secures rail plate brackets to cabinet’s EIA rails
8	8-32 screws	Secures the rails to the cabinet rails
2	Locking clips	Stabilizes the back of the array in the cabinet

TABLE 4 Sun Rack 900/1000 Cabinet Mounting Hardware (J4400 Array)

Quantity	Description	Purpose
4	M6 rail plate brackets	Attaches to a threaded EIA (vertical) cabinet rails
8	M6 screws	Secures rail plate brackets to cabinet’s EIA rails
16	8-32 screws	Secures the rails to the cabinet rails
2	Locking clips	Stabilizes the back of the array in the cabinet

1. Starting at the bottom of the cabinet, locate the appropriate rack unit (RU) height. The J4200 array requires two standard mounting units (2RU) and the J4400 array requires four standard mounting units (4RU) of vertical space in the cabinet.

Note - Each standard rack unit (RU) consists of three mounting holes in the left and right cabinet rails.

2. Start at the front of the cabinet. Install one of the M6 rail plate brackets to each side of the rack (see FIGURE 3).

a. With the text on the bracket facing toward you, align the two pins of the rail plate bracket with the holes on the cabinet rail.

b. For the J4200 and J4400 rack mounting plates, insert an M6 screw in the lower hole and tighten. For the J4400, insert an additional M6 screw in the top hole.

3. At the back of the cabinet, repeat step 2 to install the remaining two M6 rail plate brackets.

FIGURE 3 Attaching the Rail Plates to the Cabinet Rail for the J4200 Array

4. For ease of installation, attach the left and right rails from the back of the cabinet. Follow these steps for the left rail:

a. Position the front of the rail inside the cabinet, and insert the rail holes onto the two pins of the front rail plate bracket.

Note - Rails are labeled L (left), Front and Rear, and R (right), Front and Rear. (See FIGURE 1.)

b. Adjust the rail length to fit the size of the cabinet.

Be sure to align the rail flange so that the mounting holes at the back correspond to those at the front of the cabinet.

c. Insert the two holes of the rail flange onto the two pins on the back rail plate bracket.

d. In the front rail bracket, insert an 8-32 screw into the first and second hole positions (into the first through fourth hole positions for the J4400 array). Use the #2 Phillips screwdriver to tighten each screw to secure the rail to the rack.

e. In the back rail bracket, insert an 8-32 screw into the first and second hole positions (into the first through fourth hole positions for the J4400 array). Use the #2 Phillips screwdriver to tighten each screw to secure the rail to the rack.

f. Repeat Step a through Step e for the right rail.

Caution - Make sure you install the front screws into the rail bracket to secure the rail to the rack and to avoid damage to the device or person installing the device.
