Safety Instructions

Use the following safety guidelines to ensure your own personal safety and to help protect your system and working environment from potential damage. For complete safety information, see the

SAFETY: Rack Mounting of Systems

Observe the following precautions for rack stability and safety.
Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals or supporting hardware.
Product Information Guide
CAUTION: Before installing systems in a rack, install front and side stabilizers on stand-alone racks
or the front stabilizer on racks joined to other racks. Failure to install stabilizers accordingly before installing systems in a rack could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizer(s) before installing components in the rack.
CAUTION: After installing 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 installation of your system and rack kit in any other rack cabinet has not been approved by any safety agencies. It is your responsibility to have the final combination of system and rack kit in a cabinet evaluated for suitability by a certified safety agency. The manufacturer disclaims all warranties and liability in connection with such combinations.
.
System rack kits are intended to be installed in an approved rack by trained service technicians. If you install the kit in any other rack, be sure that the rack meets the specifications.
Before working on the rack, make sure that the stabilizers are secured to the rack, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.
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.
Do not overload the AC 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.
Rack Installation Guide 5

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 system 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)

Before You Begin

Before you begin installing your system in the rack, carefully read "Safety Instructions," found earlier in this guide, as well as the safety instructions found in your 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.
CAUTION: Rack cabinets can be extremely heavy and move easily on their casters. They do not have
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.
Product Information Guide
NOTE: For instructions on installing the system itself, see "Installing the System in the Rack."

Important Safety Information

Observe the safety precautions in the following subsections when installing your system in the rack.
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 precaution becomes increasingly important when systems are installed high up in the rack.
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.

Rack Requirements for VersaRails

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 (ANSI)/Electronic Industries Association (EIA) standard ANSI/EIA-310-D-92, International Electrotechnical Commission (IEC) 297, and Deutsche Industrie Norm (DIN) 41494. One rack kit is required for each system that is installed in a rack.
6 Rack Installation Guide

Four-Post Rack Installation

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

Rack Stabilizer Feet

CAUTION: Before installing systems in a rack, install front and side stabilizers on stand-alone racks
or the front stabilizer on racks joined to other racks. Failure to install stabilizers accordingly before installing systems in a rack could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizer(s) before installing components in the rack.
The stabilizer feet help prevent the rack from tipping over. See the documentation provided with the rack cabinet for instructions on installing and anchoring the stabilizer feet.

Removing the Rack Doors

See the procedures for removing doors in the documentation provided with your rack cabinet.
CAUTION: Because of the size and weight of the rack cabinet doors, never attempt to remove or install
them by yourself.
CAUTION: Store the doors where they will not injure someone if the doors accidently fall over.

Marking the Rack

For a 1-U system, you must allow 1 U (44 mm, or 1.75 inches) of vertical space for each system you install in the rack.
Rack cabinets that meet EIA-310 standards have an alternating pattern of three holes per rack unit with center-to-center hole spacing (beginning at the top hole of a 1-U space) of 15.9 mm, 15.9 mm, and 12.7 mm (0.625 inch, 0.625 inch, and 0.5 inch) for the front and back vertical rails (see Figure 1-3). Rack cabinets may have round or square holes.
NOTE: The vertical rails may be marked by horizontal lines and numbers in 1-U increments. If you want,
you can make a note of the number marking on the rack’s vertical rail. It is not necessary to mark or place tape on the rack.
Figure 1-3. One Rack Unit
1 U (44 mm or 1.75 inches)
CAUTION: If you are installing more than one system, install the mounting rails so that the first system
is installed in the lowest available position in the rack.
10 Rack Installation Guide
12.7 mm (0.5 inch)
15.9 mm (0.625 inch)
15.9 mm (0.625 inch)
12.7 mm (0.5 inch)
To mark the rack, perform the following steps:
1
Place a mark (or tape) on the rack's front vertical rails where you want to locate the bottom of the system you are installing in the rack.
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 44 mm (1.75 inches) above the original mark you made (or count up three holes in a rack that meets EIA-310 standards) and mark the rack's front vertical rails with a felt­tipped 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).
