Mounting the Array in Racks and Cabinets
This document describes mounting Sun StorEdge 3000 Family 1U arrays in supported racks and cabinets.
Topics covered in this chapter are:
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:
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 30 minutes if you follow all the instructions provided in this guide.
These rack kits are available for all Sun StorEdge 3000 Family 1U (1.75 inches) arrays. The term array is used to refer to any of the Sun StorEdge 3000 Family products.
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.

Two people should install each array; however, one person can install the array:
For a one-person installation, you should 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 for 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 Installation, Operation, and Service Manual and follow instructions on removing drives and power supplies for the Sun StorEdge 3120 SCSI array. A fully populated array weighs over 32 pounds (14.51 kilograms); an array without drives and power supplies weighs about 25 pounds (11.34 kilograms).
The following tools are used to complete this procedure:
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.
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.
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.
8. Replace the bezel.
