Rack Installation Instructions

This installation guide provides instructions for trained service technicians installing a 48-unit (U) rack. Information includes assembling the rack, coupling two 48-U racks, and routing cables through the rack. The 48-U rack can be installed using the recommended tools.

Before attempting this installation, you should read through this entire procedure carefully.

Rack Requirements

CAUTION: The 48-U rack meets the specifications of American National Standards

Institute (ANSI)/Electronic Industries Association (EIA) standard ANSI/EIA-310-D-92, Consumer Electronics Association (CEA) Standard CEA-310-E, International Electrotechnical Commission (IEC) 297, and Deutsche Industrie Norm (DIN) 41494.

Before You Begin

WARNING: Before you begin installing your rack, carefully read "Important

Safety Information," as well as the safety instructions that came with the rack.

WARNING: When installing multiple systems in a rack, complete all of the

procedures for the current system before attempting to install the next system.

WARNING: Rack cabinets can be extremely heavy and move easily on the

casters. The cabinet has no brakes. Use extreme caution while moving the rack cabinet. Retract the leveling feet when relocating the rack cabinet. Avoid long or steep inclines, rough surfaces, or ramps where loss of cabinet control may occur. Extend the leveling feet for support and to prevent the cabinet from rolling.

WARNING: Avoid rolling the rack cabinet over rough surfaces. Hard impacts to

the casters could cause them to break, and the rack could become unstable and tip over.

WARNING: Do not attempt to move your rack with components installed. If you

move a fully loaded rack on a slightly uneven floor surface, the rack may become unstable and tip over.

6 Installation Guide

Important Safety Information

Observe the safety precautions in the following subsections when installing your system in the rack.

WARNING: You must strictly follow the procedures in this document to protect

yourself as well as others who may be involved. Your system may be very large and heavy, and proper preparation and planning are important to prevent injury to yourself and to others. This becomes increasingly important when systems are installed high up in the rack.

Rack Stabilizer Feet

WARNING: Installing systems in a rack without the front and side stabilizer feet

installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizer feet before installing components in the rack.

WARNING: After installing systems in a rack, never pull more than one system

out of the rack on its slide assemblies at one time. The weight of more than one extended system could cause the rack to tip over and cause injury.

The stabilizer feet help prevent the rack from tipping over when a system or other component is pulled out of the rack with the slide assemblies fully extended.

Securing the Rack Leveling Feet

WARNING: Read all statements below before you adjust the leveling feet.

Your rack includes four leveling feet, which are mounted on the corners of the rack. The leveling feet are designed to align the rack in an upright, level position when the rack is situated on a slightly uneven floor surface. Before you install your systems in the rack, deploy and adjust the leveling feet. When you level your rack, follow these guidelines.

WARNING: When you adjust the leveling feet, ensure that the casters on each

corner of the rack do not rise more than 9.5 mm (3/8 inch) above the floor. If you exceed 9.5 mm of clearance between the floor and the casters as you adjust the leveling feet, slowly retract the leveling feet, and then move the rack to another location that requires minimal adjustments to the leveling feet.

WARNING: Adjust the leveling feet until each leveling foot rests firmly on the

floor. Proper contact with the floor ensures that each leveling foot is supporting the weight of the rack and prevents the rack from swaying in any direction. If the leveling feet are not all in firm contact with the floor, the rack can become unstable and tip over.

WARNING: Do not attempt to move your rack with the leveling feet deployed.

Always retract the leveling feet before moving the rack. Having the leveling feet deployed when you move the rack may cause the rack to tip over.

WARNING: Always level the rack and install the stabilizing feet before you

install your systems. A fully loaded rack may tip over if your rack is resting on an uneven floor surface and the leveling and stabilizing feet are not supporting the weight of the rack.

NOTE: If the rack is not leveled properly, you might not be able to install the

stabilizer feet, which are necessary to prevent the rack from tipping over.

22 Installation Guide

Using a screwdriver, lower the leveling foot until it rests on the floor.

If you need to lower the foot further, tighten the hex nut clockwise with a 12-mm wrench (see Figure 1-11).

Repeat steps 1 and 2 for the remaining leveling feet.

Ensure that the rack is level.

Installation Guide 23

Installing the Rack Stabilizer Feet

WARNING: Installing systems in a rack without the front and side stabilizer feet

installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizer feet before installing components in the rack.

Install stabilizer feet on the rack as follows:

• Install front and side stabilizer feet on a standalone rack.

• Install front stabilizer feet on all racks in a suite, and install left or right stabilizer feet on the racks at each end of a suite.

Installing the Front Stabilizer Feet

Open the front door.

Reach into the rack and pull up firmly on each stabilizer to detach them from the frame.

Remove the plastic fasteners attached to the stabilizer feet.

Position each front stabilizer foot against the base of the rack frame and align its holes with the corresponding holes in the frame.

Use the provided bolts, washers, and cage nuts to secure each foot to the rack as shown in Figure 1-12.

Installation Guide 27

Routing Cables

The 48-U rack offers several features that simplify cable routing (see Figure 1-15).

• The power distribution unit (PDU) channels in each rack flange allow you to route power cables to the systems mounted in the rack.

• Cable clips can be mounted in the PDU channels to keep cables out of the way and help prevent cords from becoming tangled.

You can route cables out of the rack in two ways on a standard configuration:

• Through the cable exit at the bottom of the back doors (see Figure 1-15)

• Through the adjustable cable slot at the top of the rack and into a cable raceway (see Figure 1-15).
