Mounting in Sun Cabinets

This chapter explains how to mount Sun StorEdge 3000 Family 1U array by using universal, adjustable mounting brackets for depth ranges between 24 to 36 inches (60.96 to 91.44 cm).

The topics covered are:

Section 2.1, Overview of Assembly

Section 2.2, Rear Bracket Configuration

Section 2.3, Middle Bracket Configuration

2.1 Overview of Assembly

Two configurations exist for Sun cabinets:

You can mount a cabinet using rear and side brackets for depth ranges between 24 to 36 inches (60.96 to 91.44 cm). FIGURE 2-1 displays a completed installation of a Sun StorEdge 3000 Family 1U array in a standard EIA cabinet using rear and side brackets.

You can mount a cabinet using middle and side brackets at 24.5 inches (62.22 cm). FIGURE 2-2 displays a completed installation of a Sun StorEdge 3000 Family 1U array in a Sun Fire cabinet using middle and side brackets.

Refer to FIGURE 2-9 during installation.

Note - It is possible for customer-supplied racks to have several sizes of threaded holes. Rackmount kits have several sizes of panhead screws and sockethead screws in order to fit these various racks. Sockethead screws are supplied for the front mounting ears when the diameter of the screw is too large for panhead screws to fit.

Note - When you finish the installation, you will have unused screws left in your rackmount kit. This does not indicate a problem with your installation. Several types of screws are included for different rack configurations, and extra screws are provided in case any are misplaced.

Before mounting the Sun StorEdge 3000 Family 1U array into a 19-inch wide cabinet, check that you have all the rackmount kit components (TABLE 2-1) listed for the rack installation kit you are installing.

2.2 Rear Bracket Configuration

Review Section 1.2, One-Person Installation Requirements and Section 1.3, Reviewing the Tools before rackmounting the array.

Refer to the parts list in TABLE 2-1 and the illustration in FIGURE 2-1 during installation. The table lists the major components and fasteners required to install an array into the cabinet.

Caution - Do not use any power tools with any procedures. Power tools can strip or damage connections.

1. Determine the position at which the array will be installed.

Install the first array at the bottom of the rack, and install each subsequent chassis above the previous one.

Note - Keep all hardware items in plastic bags until you are ready to use them. This will enable you to correctly identify the screws and avoid confusion.

2. Before rackmounting, be sure to check your site location and confirm that you have cables with adequate lengths to connect to servers and to power outlets.

3. (Optional). Before you mount the unit, screw the front support brackets (79-00000100) into position on the rack face. The front support brackets enable one person to easily position and support the front of the unit in the rack.

a. Attach each front bracket to the rack face (See FIGURE 2-3):

To connect the front brackets (79-00000100), use a minimum of two screws per front bracket.

Use the appropriate screws for the rack:

#10-32 x 3/8-inch (01-00000192) panhead screws
or

5-mm (01-00000150) panhead screws
or

6-mm (01-00000152) panhead screws

FIGURE 2-3 Front Bracket Position on the Rack Face

Figure showing the front bracket position on the rack face.

4. Remove the bezel (the front faceplate) and the two plastic ear caps from the front of the chassis.

Caution - The plastic ear covers are snap-on parts that require some care when you remove them. Remove the right plastic ear caps carefully to avoid breaking the push button reset switch that is directly behind the ear cap.

To remove a plastic ear cap (both caps are removed the same way):

a. Grasp both sides of the cap.

b. With minimal force, pull the cap straight out from the array until it disengages.

FIGURE 2-4 Cabinet Rackmount with Rear Brackets

Figure showing a cabinet rackmount using rear brackets.

Note - Alternate screws can be used with the appropriate racks: 5-mm panhead screws (front and back), or 6-mm sockethead screws (front) and 6-mm panhead screws (back).

Note - Keep all hardware items in plastic bags until you are ready to use them. This will enable you to correctly identify the screws and avoid confusion.

5. Attach the side brackets to the left and right sides of the chassis.

Attach up to eight #8-32 x 3/16-inch flathead machine screws (01-00000142) on each side to allow some adjustment to the placement. Make sure you use at least four screws on each side (six screws per side is recommended).

FIGURE 2-5 Side Brackets

Figure displaying the right and left side brackets.

Note - The right and left side brackets may look identical, but they are slightly different. Each side bracket is clearly stamped with numbers. Position the side brackets with the number side of the bracket facing out and the holes closest to the edge of the bracket mounted to the bottom of the chassis. See TABLE 2-1 for the rack kit contents and part numbers.

a. Use the alignment marks (depth in inches) stamped into the side brackets to position the brackets and screws.

There are markings for several depths: 24, 24.5, 26, 27, 28, 30, 32, 34, and 36 inches.

Determine the depth you require and align the last (rearmost) alignment mark for each depth on the side bracket to the last mounting holes on the chassis.

Make sure the alignment mark corresponding to the depth you want lines up with the top and bottom threaded holes on the side of the chassis closest to the rear.

b. Insert the first two screws on each side through the side bracket slots above and below the appropriate alignment mark (24, 24.5, 26, 27, 28, 30, 32, 34, or 36) and into the last pair of rear threaded holes in the chassis.

In the illustration below, the 34-inch alignment mark is positioned above and below the last pair of rear threaded holes. This positions the array for a 34-inch deep rack.

c. Insert up to six other screws through the side bracket slots into the other threaded holes in the chassis. Use a minimum of four screws for each side bracket.

6. Attach the rear brackets to the rear vertical posts using a total of four screws and four washers (two screws to attach each bracket to a post). (See FIGURE 2-4.)

Attach each rear bracket with two of the appropriate screws for the posts:

#10-32 x 3/8-inch panhead screws (01-00000192) with #10 washers (02-00000018)
or

5-mm panhead screws (01-00000150) with #10 washers (02-00000018)
or

6-mm panhead screws (01-00000152)

or

5-mm panhead screws (01-00000150)
or

6-mm socket cap screws (01-00000151)

Note - You will have unused screws left in your rackmount kit. This does not indicate a problem with your installation. Several types of screws are included for different rack configurations, and extra screws are provided in case any are misplaced.

9. Remount all drives and power/fan modules into the array.

10. If you mounted the unit using the optional front support brackets, remove them from the rack face using a standard screwdriver.

11. Reattach the two plastic ear caps and the bezel onto the front of the chassis.

Each plastic cap is replaced the same way, but be sure the cap with the LED labels on the right ear.

a. Align the inside round notches of the cap with the round cylindrical posts (ball studs) on the ear.

b. Push the top and bottom of the ear cap onto the ear, pressing in toward the center of the array.

c. Continue pushing the top and bottom of the ear cap onto the ear until the ear cap snaps in flush.

Do not use force when placing a cap on an ear.

Caution - Be careful to avoid "wedging" the reset button below the LEDs on the right ear when you replace the plastic cap over it.

d. Insert the bezel swing arms into the chassis ear holes.

e. Lift the bezel into position and press it onto the front of the chassis until it is flush with the front.

f. Use the key to lock both bezel locks.
