CHAPTER 1
Mounting the Array in Racks and
Cabinets
This document describes mounting Sun StorEdge 3000 Family arrays in supported
racks and cabinets. Topics covered in this chapter are:
■“Overview of Rackmount Kits” on page 1-1
■“One-Person Installation Requirements” on page 1-2
■“Reviewing the Tools” on page 1-3
■“Converting Your Front Bezel Locks So the Keys Cannot Be Removed” on
page 1-4
1.1 Overview of Rackmount Kits
For late-breaking news about additional supported racks and cabinets, refer to the
Release Notes for the model of the array that you are installing. You can find the
Release Notes at:
http://www.sun.com/products-n-solutions/hardware/docs/
Network_Storage_Solutions/Workgroup/3310
Tip – The instructions in this guide can save you a lot of time if you read them
carefully. The entire assembly procedure should take less than thirty minutes if you
follow all the instructions provided in this guide.
The following table lists the supported cabinets and racks and other required kits,
the rackmount kits that apply to each one, and the location of the installation
instructions in this guide.

1-2 Sun StorEdge 3000 Family Rack Installation Guide for 2U Arrays • September 2003
* The Sun StorEdge 72-inch expansion cabinet requires the X9818A door kit for the Sun StorEdge 3000 Family 2U
arrays.
**The Sun Rack 900 cabinet also requires the X6825A door kit and the X6835A EMI kit with these arrays.
1.2 One-Person Installation Requirements
Two people should install each array; however, one person can install the array:
■In a Sun cabinet if the rail kit contains rear brackets with flanges that provide
support
■In a Telco rack if the person has an appropriate equipment lift that can ensure
safety and ease of installation
For a one-person installation, remove the power supplies and disk drives to reduce
weight and to be safe. If possible, position the array on top of another device or shelf
in the rack to hold the unit as you attach all the brackets.

Caution – If you have only one person to perform the installation in a Sun cabinet
and do not have rear brackets with flanges or special equipment lift, you must
remove the power supplies and hard disk drives from the array before installing the
array in a rack.
To reduce the weight of the array during the rackmounting procedure, refer to the
Sun StorEdge 3000 Family FRU Installation Guide for your array, and follow
instructions on removing drives and power supplies. A fully populated array weighs
over 50 pounds; an array without drives and power supplies weighs about 30
pounds.
1.3 Reviewing the Tools
The following tools are used to complete this procedure:
■Medium Phillips screwdriver
■Allen wrench (provided; used with 6-mm screws and #12-24 x 3/8-inch
sockethead screws)
Caution – Do not use any power tools with any procedures. Power tools can strip
or damage connections.

1.4 Converting Your Front Bezel Locks So
the Keys Cannot Be Removed
The bezel on your array has two locks whose keys can be removed when the locks
are in either the locked or open position. It is possible to reconfigure the locks so that
the keys cannot be removed. It is most convenient to make this optional change
when removing the bezel prior to installing the array in a rack or cabinet.
FIGURE 1-1 Front Bezel and Front Bezel Locks of an Array
To change the locks so the keys cannot be removed, follow these steps:
1. Remove the bezel by gently pivoting the swing arms out of their ear sockets, and
make sure the key is in the locked position, with the pawl extending horizontally
past the edge of the bezel (see the first panel of FIGURE 1-2).
2. Hold the key in place and use a 12-mm or 3/8-inch nut driver to remove the
locking nut that holds the pawl in place, as shown in the first panel of FIGURE 1-2.
Caution – Be sure to hold the key in place. Otherwise there is a risk of breaking the
small tab on the lock that serves as a stop.
3. Lift the pawl off the threaded part of the lock body, as shown in the second panel
of FIGURE 1-2.
4. Set the pawl aside, face up, so that you can remember its orientation when you
replace it.
5. Use the key to turn the lock 180 degrees, as shown in the third panel of FIGURE 1-2
6. Replace the pawl in the same orientation as before, as shown in the fourth panel
of FIGURE 1-2.
7. Hold the key in place and use the nut driver to refasten the locking nut that holds
the pawl in place, as shown in the fifth panel of FIGURE 1-2. Be careful not to cross-
thread the nut.

CHAPTER 2
Mounting in Sun Cabinets
This chapter explains how to mount Sun StorEdge 3000 Family arrays by using
universal, adjustable mounting brackets for depth ranges between 24 to 36 inches
(60.96 to 91.44 cm).
The topics covered are:
■“Overview of Assembly” on page 2-1
■“Rear Bracket Configuration” on page 2-4
■“Middle Bracket Configuration” on page 2-12
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 2U 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 2U
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.

2-4 Sun StorEdge 3000 Family Rack Installation Guide for 2U Arrays • September 2003
Before mounting the Sun StorEdge 3000 Family 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
Be sure to review “One-Person Installation Requirements” on page 1-2 and
“Reviewing the Tools” on page 1-3 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 “Mounting Holes in the Sun StorEdge 72-
Inch Expansion Cabinet” on page A-1.
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 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, use a minimum of two #10-32 x 3/8-inch panhead
screws per front bracket.
FIGURE 2-3 Front Bracket Position on the Rack Face

2-6 Sun StorEdge 3000 Family Rack Installation Guide for 2U Arrays • September 2003
4. Remove the bezel (the front faceplate) and the two plastic ear caps from the front
of the chassis.
Caution – The plastic ear caps 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 below the ear cap.
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 – 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.
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.
FIGURE 2-5 Side Bracket With Alignment Marks
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 24.5 - 27-inch alignment mark is positioned above and below the
last pair of rear threaded holes. This positions the array for a 27-inch deep rack.
