Safety Instructions

Use the following safety guidelines to ensure your own personal safety and to help proteet your server, storage system, or applianee from potential damage. For eomplete safety and regulatory information, refer to your System Information doeument. Warranty information might be ineluded within this doeument or as a separate doeument.

/t\ CAUTION: Precautions for Rack-Mountable Products

Observe the following preeautions for raek stability and safety. Also refer to the raek installation doeumentation aeeompanying the system and the raek for speeifie warning and/or eaution statements and proeedures.

Servers, storage systems, and applianees are eonsidered to be eomponents in a raek. Thus, "eomponent" refers to any server, storage system, or applianee, as well as to various peripherals or supporting hardware.

/t\ CAUTION: Installing system components in a rack without the front and side

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

After installing system/components in a rack, never pull more than one component out of the rack on its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip over and injure someone.

^ NOTE: Your system is safety-certified as a free-standing unit and as a component for

use in a rack cabinet using the customer rack kit when both the rack cabinet and rack

kit were designed for your system. The instaiiation of your system and rack kit in any

other rack cabinet has not been approved by any safety agencies. It is your

responsibiiity to have the finai combination of system and rack kit in a cabinet evaiuated for suitabiiity by a certified safety agency. The manufacturer disciaims aii warranties and iiabiiity in connection with such combinations.

• System raek kits are intended to be installed in an approved raek by trained serviee teehnieians. If you install the kit in any other raek, be sure that the raek meets the speeifieations.

CAUTION: Do not move large racks by yourself. Due to the height and weight of

the rack, it is recommended that a minimum of two people perform this task.

Before working on the raek, make sure that the stabilizers are seeured to the raek, extend to the floor, and that the full weight of the raek rests on the floor. Install front and side stabilizers on a single raek or front stabilizers for joined multiple raeks before working on the raek.

Rack Instaiiation Guide

I 1-1

• Always load the rack from the bottom up, and load the heaviest item in the rack first.

• Make sure that the rack is level and stable before extending a component from the rack.

• Use caution when pressing the component rail release latches and sliding a component into or out of a rack* the slide rails can pinch your fingers.

• After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack.

• Do not overload the power supply branch circuit that provides power to the rack.

The total rack load should not exceed 80 percent of the branch circuit rating.

• Ensure that proper airflow is provided to components in the rack.

• Do not step on or stand on any system/component when servicing other systems/components in a rack.

Installation Instructions

This installation guide provides instructions for trained service technicians installing one or more systems in an open-frame relay rack or in a rack cabinet. The RapidRails™ rack kit can be installed in all the manufacturer’s rack cabinets without tools, and the VersaRails™ rack kit can be installed in most industry-standard rack cabinets. The procedures for installing both RapidRails and VersaRails rack kits are similar. One rack kit is required for each system to be installed in the rack cabinet.

This guide includes procedures for the following rack kits:

• RapidRails kit in a four-post rack cabinet

• VersaRails kit in a four-post rack cabinet

• Two-post kit (installed in either center-mount or flush-mount configuration, for 7- or 6-inch-wide racks)

For ease in troubleshooting and the identification of system health, these rack kits include a status-indicator cable that extends the information on the two-color status indicators on the front and back panels to the back of the cable-management arm. For more information on these indicators, your system User’s Guide.

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

/l\ CAUTION: Do not install rack kit components designed for another system. Use

only the rack kit for your system. Using the rack kit for another system may result in damage to the system and personal injury to yourself and to others.

1-2 I Rack Installation Guide

Rack Requirements for VersaRails

О NOTICE: The VersaRails rack kit is intended to be installed by trained service

technicians in a rack that meets the specifications of American National Standards Institute (ANSD/Electronic Industries Association (EIA) standard ANSI/EIA-310-D-92, International Electrotechnical Commission (lEC) 297, and

Deutsche Industrie Norm (DIN) 41494. One rack kit is required for each system that is installed in a rack.

Four-Post Rack Installation

Before attempting this installation, you should read through this entire proeedure earefully.

Before You Begin

Before you begin installing your system in the raek, earefully read "Safety Instruetions," found earlier in this guide, as well as the safety instruetions found in your system’s System Information doeument for additional information.

!\ CAUTION: When installing multiple systems in a rack, complete all of the

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

/t\ CAUTION: 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 or ramps where loss of cabinet control may occur. Extend the leveling feet for support and to prevent the cabinet from rolling.

Important Safety Information

Observe the safety preeautions in the following subseetions when installing your system in

the raek.

/t\ CAUTION: 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

CAUTION: 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.

Rack Installation Guide | 1-3

/К CAUTION: 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 гаек from tipping over when a system or other eomponent is pulled out of the raek with the slide assemblies fully extended. Refer to the doeumentation provided with the raek eabinet for instruetions on installing and anehoring the stabilizer feet.

/t\ CAUTION: If you are installing more than one system, install the slide assemblies

so that the first system is installed in the lowest available position in the rack.

To mark the rack, perform the following steps:

1 Place a mark on the rack’s front vertical rails where you want to locate the bottom of

the system you are installing in the rack cabinet. The bottom of each 1-U space is at the middle of the narrowest metal area between

holes (marked with a horizontal line on some rack cabinets—see Figure 1-4).

2 Place a mark 88 mm (5.5 inches) above the original mark you made (or count up six

holes in a rack that meets EIA-510 standards) and mark the rack’s front vertical rails with a felt-tipped pen or masking tape (if you counted holes, place a mark just above the top hole). This mark or piece of tape indicates where the system’s upper edge will be located on the vertical rails (see Figure 1-4).
