Introduction
For proper operation, a PS4000 storage array must be installed in a rack. See your PS Series support
provider for information about supported racks.
Before You Begin
Before you begin to mount an array in a rack, you must:
•Read the installation safety precautions. See Installation Safety Precautions.
•Make sure the rack location meets the array’s environmental requirements. See Installation
Environmental Requirements.
•Make sure your rack meets the rack requirements. See Rack Requirements.
•Unpack the rail kit and make sure you have all the necessary parts and tools. The rail kit is located in
the array shipping box. You must supply your own tools. See Rail Kit Parts and Tool Requirements.
Installation Safety Precautions
Follow these safety precautions:
•It is recommended that only individuals with rack mounting experience install a PS4000 array in a
rack.
•Make sure the array is fully grounded at all times to prevent damage from electrostatic discharge.
•When handling the array hardware, you must use the electrostatic wrist guard shipped with the array
or a similar form of protection.
•You need at least two people to lift the array chassis from the shipping box.
Installation Environmental Requirements
The rack location must meet the following environmental requirements:
•Only operate an enclosure from a power source with a voltage range of 100 to 240 VAC.
•Make sure your power source has sufficient electrical overload protection.
•In North America, connect the enclosure to a source of power with over-current protection provided
by a double pole 20A or less device (UL 489 circuit breakers). In Europe, the over-current protection
must be provided by a 20A or less device (IEC circuit breakers).
•Make sure there is sufficient space for air flow in front of and behind the array.
•Make sure the location is properly vented.
•Make sure the rack installation meets the array technical specifications in Table 1.

•The distance between the inside of the front and rear rack poles (the mounting surfaces) must be
61 cm (24 inches) to 90 cm (36 inches).
•Secure the rack to the floor for added stability.
•Load a rack with arrays from the bottom to the top.
•There must be at least 4.1 cm (1.6 inches) between the rack door and the front of the array to
accommodate the array front bezel.
•The rack (with installed arrays) must meet the safety requirements of UL 60950-1 and IEC 60950-1.
•Mount the array in a horizontal position, or you will void your array warranty and support contract.

Steps for Mounting an Array in a Rack
Follow these steps to mount a PS4000 array in a rack:
1. Change the mounting rail hardware, if necessary.
2. Determine where to place the mounting rails in the rack.
3. Attach the mounting rails to the rack.
4. Slide the chassis into the rack.
5. Attach the chassis to the brackets on the mounting rails and to the front of the mounting rails.
6. Install the bezel.
These steps are described in detail in the following sections. After you mount the array in the rack, see the
Installation and Setup manual for information about completing the array hardware installation.
Step 1: Change the Mounting Rail Hardware
The mounting rails are shipped with hardware pre-installed for mounting in a rack with square holes. If
you have a square-hole rack, no changes are necessary. Proceed with Step 2: Determine Where to Place
the Mounting Rails in the Rack.
If your rack has round or tapped holes, change the hardware as follows.
•For round hole racks:
- On the front and back of both mounting rails, remove the pre-installed locator pins and replace
them with the locator pins from the bag labeled ROUND. Insert the locator pins from the front,
using the same orientation as the pre-installed pins.
•For tapped hole racks:
1. On the front and back of both mounting rails, remove the pre-installed locator pins.
2. Re-install the same locator pins from the opposite side of the holes you removed them from, so
that the pin protrudes from the front and rear of the mounting rail flanges.
Step 2: Determine Where to Place the Mounting Rails in the Rack
Make sure there is enough space in the rack for a 3U chassis. In a standard rack, the height of a 3U
chassis will span 9 holes.
Figure 1 shows the location of the top and bottom of the chassis relative to the location of the screws used
to attach the rail and the array to the rack’s front right and left poles.

Step 3: Attach the Mounting Rails to the Rack Poles
The rail kit includes two mounting rails, one for the left rack pole and one for the right rack pole when
viewed from the front of the rack.
Guidelines for Attaching the Mounting Rails
Follow these guidelines when attaching the mounting rails to the rack poles:
•Attach the mounting rail flanges to the inside of the rack pole flanges.
•Insert the screws from the outside of the rack.
•Use the markings on the rack poles (if present) to make sure the rails are level, or use a level.
Attaching the Mounting Rails to the Rack Poles
To attach the mounting rails to the rack poles:
1. Collect the necessary hardware and tools:
- One #2 Phillips screwdriver and one #2 pozidriv screwdriver. See Tool Requirements.
- The left and right rails.
- For all rack types, the contents of the COMMON BAG.
PS4000 Rack Mount Instructions 5

2. Orient the mounting rail in its proper position. Each rail is stamped with either “LH Front” or “RH
Front.” When the rails are properly positioned, the brackets are closer to the rear of the rack and
pointing up. See Figure 2.
Figure 2 Adjusting the Length of a Mounting Rail
3. Attach the front of the rail to the inside of the front pole (Figure 3, callout ) using one Phillips head
screw, one spring washer, and one plain washer from the COMMON bag.
4. Pull the rear flange until it meets the inside surface of the rear rack pole. See Figure 2.
Make sure the locator pins go through the rack holes at the same height (in the same relative holes on
the front and rear poles), according to the pole markings, if present. Use a level to make sure the rails
are level.
5. Attach the rear of the rail to the rear pole (Figure 3, callout ) using one Phillips head screw, one
spring washer, and one plain washer from the COMMON bag.

Step 4: Slide the Chassis into the Rack
Caution: Be careful when lifting the chassis.
1. With assistance, lift the chassis and slide it into the mounting rails. Keep the chassis level.
See Figure 4.
2. Make sure the chassis captive fasteners on the front of the array line up with the lower clip nuts in the
front of the mounting rails.
Figure 4 Sliding the Chassis into the Rack
PS4000 Rack Mount Instructions 7

Step 5: Attach the Chassis to the Mounting Rails
Secure the chassis to the mounting rails as follows:
1. On both sides, tighten the captive fasteners on the front of the chassis into the lower clip nuts. See
Figure 5.
2. On both sides, attach the rear of the chassis to the brackets on the left and right rails using the Posi
screws from the COMMON bag. Insert the screws from the inside of the rack, as shown in Figure 5
(shows only one side for clarity). You must secure the array to the rear brackets.
Caution: Failure to attach the array to the brackets can affect the stability of the array and reduce the
life of the drives.

Step 6: Install the Bezel
1. Facing the front of the rack, fit the right side of the bezel into the right side of the chassis.
See Figure 6.
Figure 6 Attaching the Bezel to the Chassis
2. Push the bezel toward the chassis until the left side of the bezel engages with the chassis.
3. Insert the bezel key (attached to the bezel) and turn it counter-clockwise to lock the bezel to the
chassis. See Figure 7. Make sure you store the key in a safe location.
