Mounting in Sun Cabinets |
This chapter explains how to mount Sun StorEdge 3000 Family 2U arrays by using universal, adjustable mounting brackets for depth ranges between 24 to 36 inches (60.96 to 91.44 cm).
Two configurations exist for Sun cabinets:
Refer to FIGURE 2-4 during installation.
Refer to FIGURE 2-9 during installation.
Before mounting the Sun StorEdge 3000 Family 2U 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.

|||||
Be sure to 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.
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.
For additional rack hole information, see Appendix A.
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:
4. Remove the bezel (the front faceplate) and the two plastic ear caps from the front of the chassis.
To remove a plastic ear cap (both caps are removed the same way):
a. Squeeze both sides of the cap at the top and the bottom.
b. Turn the cap toward the center of the array until it disengages and pull it free.
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). |
5. Attach the side brackets (71-00000762) to the left and right sides of the chassis.
Attach up to eight #8-32 x 3/16-inch (01-00000142) flathead machine screws on each side to allow some adjustment to the placement. Make sure you use at least four screws on each side.
Note - The right and left side brackets are identical. 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, 26, 24.5-27, 28, 30, 32, 34, and 36 inches.
Determine the depth you require, and align the last alignment mark on the side bracket with 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 alignment mark and into the last pair of rear threaded holes in the chassis.
In FIGURE 2-6 the alignment marks (24, 26, 24.5-27, 28, 30, 32, 34, or 36 inches) are positioned above and below the last pair of rear threaded holes. This positions the array for a 27-inch deep rack.
c. Insert up to six other screws through the side bracket slots into the other threaded holes in the chassis.
6. Use a total of four screws and four washers to attach the rear brackets to the rear vertical posts (two screws to attach each bracket to a post).
a. Attach each rear bracket with two screws.
Use the appropriate type of screws for the posts:
7. Lift the chassis and slide the side brackets into the rear brackets, which are attached to the rear posts.
Adjust the depth of these brackets so that the rear slotted cutouts on the side brackets align with the four PEM nuts in the rear brackets.
8. Attach each side bracket to a rear bracket (see FIGURE 2-7):
To connect the rear brackets and side brackets of a 24-inch to 36-inch deep rack, use a minimum of four screws each and up to a total of four #8-32 x 1/4-inch (01-00000186) panhead screws per bracket.
9. Attach and secure the array's front mounting ears with four appropriate screws (two screws into each ear):
10. Remount all drives and power/fan modules into the array.
11. If you mounted the unit using the optional front support brackets, remove them from the rack face using a standard screwdriver.
12. 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 is 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 on the top side toward the center of the array first.
c. Continue pushing the top and bottom of the ear cap onto the ear, pressing on the side toward the outside of the array.
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 arms into the chassis 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.
13. Connect power cables to the chassis, power up, and check for proper operation of the LEDs.
For details on powering on and checking LEDs, see Chapter 4.
Be sure to 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 2-2 during installation. The table lists the major components and fasteners required to install an array into the cabinet.

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 2-8):
To connect the front brackets (79-00000100), use a minimum of two screws per front bracket.
Use the appropriate screws for the rack:
4. Remove the bezel (the front faceplate) and the two plastic ear caps from the front of the chassis.
To remove a plastic ear cap (both caps are removed the same way):
a. Squeeze both sides of the cap at the top and the bottom.

*Flanged middle brackets support the side brackets and enable an easy one-person installation.
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). |
5. Attach the side brackets to the left and right sides of the chassis.

In FIGURE 2-11 the alignment marks (24, 26, 24.5-27, 28, 30, 32, 34, or 36 inches) are positioned above and below the last pair of rear threaded holes. This positions the array for a 24.5-inch deep center rail for mounting the middle bracket.
c. Insert up to six other screws through the side bracket slots into the other threaded holes in the chassis.
6. Use a total of four screws (01-00000192) and four washers (02-00000018) to mount the middle brackets to the rack vertical center posts (two screws to attach each bracket to a post).
a. Insert a minimum of two screws through the side bracket slots and through the middle bracket holes. (See FIGURE 2-9).
Use the appropriate type of screws for the posts:
7. Lift the chassis and slide the side brackets into the middle brackets, which are attached to the center posts.
Adjust the depth of the side brackets so that the slotted cutouts on the side brackets align with the four PEM nuts in the middle brackets.
8. Attach each side bracket to a middle bracket (see FIGURE 2-12):
To connect the middle brackets (71-00000748) and side brackets of a 24-inch to 36-inch deep rack, use a minimum of four screws each and up to a total of four #8-32 x 1/4-inch (01-00000186) panhead screws per middle bracket.
