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.

Rack Requirements

Make sure the rack and the array installation meet the following requirements:

•Use an industry-standard (for example, CEA-310-E), four-pole, 19 inch (48.3 cm) rack.

•The rack must be rated for 540 kg (1200 pounds) static load or greater.

•The minimum rack depth is 100 cm (40 inches) from the front of the rack to the rear of the rack.

•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.

PS4000 Rack Mount Instructions 3

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.

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.
