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 and regulatory information, see the

Guide

that shipped with your system. Warranty information might be included

in this document or as a separate document.

SAFETY: Rack Mounting of Systems

Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the system and the rack for specific caution statements and procedures.

Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals or supporting hardware.

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.

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 may result in serious injury.

Product Information

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

for use in a Dell™ rack cabinet using the customer rack kit. 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 ensure that the final combination of system and rack complies with all applicable safety standards and local electric code requirements. Dell disclaims all liability and warranties in connection with such combinations.

• System rack kits are intended to be installed in a rack by trained service technicians. If you install the kit in any other rack, be sure that the rack meets the specifications of a Dell rack.

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

of the rack, a minimum of two people should accomplish this task.

Rack Installation Guide 5

• Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, 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.

• 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.

• Do not overload the AC 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 component when servicing other components in a rack.

General Installation Instructions

This installation guide provides instructions for trained service technicians installing one or more systems in a rack cabinet. The RapidRails™ configuration can be installed without tools in manufacturer's rack cabinets that have square holes; the VersaRails™ configuration can be installed in most industry-standard rack cabinets that have square or round holes. One rack kit is required for each system to be installed in the rack cabinet.

6 Rack Installation Guide

Before You Begin

Before you begin installing your system in the rack, carefully read "Safety Instructions" on page 5, as well as the safety instructions found in your

Product Information Guide

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.

NOTE: For instructions on installing the system itself, see "Installing the System

in the Rack" on page 18.

for additional information.

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 the Consumer Electronics Association (CEA) standard CEA-310-E, 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.

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 two doors where they will not injure someone if the doors

accidently fall over.

Marking the Rack

You must allow 10 U (44.45 cm or 17.5 inches) of vertical space for each system you install in the rack (see Figure 1-3).

NOTE: Your rack may already be marked and not require this procedure.

CAUTION: If you are installing more than one system, install the rail assemblies

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

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 1-3).

Installing the RapidRails Assemblies

At the front of the rack cabinet, position one of the RapidRails assemblies so that its mounting-bracket flange fits in the appropriate location on the rack (see Figure 1-5).

The lower mounting tab on the rail assembly’s front-mounting bracket flange should enter the tenth hole up from the lower mark on the vertical rails (see Figure 1-5).

Push the rail assembly forward until the top mounting tab enters the square hole, which is located 4-U spaces below the upper marks or tape you placed on the vertical rail (see Figure 1-5).

Next, push down on the mounting-bracket flange until the mounting tabs seat in the square holes and the push button pops out and clicks (see Figure 1-5).

At the back of the cabinet, pull back on the mounting-bracket flange until the mounting tabs are in the appropriate holes, and then push down on the flange until the mounting tabs seat in the square holes and the push button pops out and clicks.

Repeat step 1 through step 4 for the rail assembly on the other side of the rack.

NOTE: Ensure that the rails are mounted at the same vertical position on both

sides of the rack.

Installing the VersaRails Assemblies

At the front of the rack cabinet, place a VersaRails assembly so that its mounting-bracket flange fits between the marks or tape (or numbered location) on the rack (see Figure 1-6).

The holes on the front of the mounting bracket should align with the holes between the marks on the front vertical rail.

NOTE: The VersaRails occupy only the lower 6-U of the 10-U space that is

required for this system.

Locate the round mounting hole indicated by the tooled arrow cutout on the VersaRails (see Figure 1-6).

Install two 10-32 x 0.5-inch flange-head Phillips screws in the front mounting flange to secure the rail assembly to the front vertical rail. See Figure 1-6.

• The upper mounting screw should be installed in the middle round

hole of the 6th-U space counting up from the bottom of the 10-U space.

• The lower mounting screw should be installed in the middle round

hole of the 1st-U space counting up from the bottom.

NOTE: The two midsection round holes on the VersaRails are for securing

your system to the rack. To assemble the VersaRails, use only the round holes indicated by the two tooled arrow cutouts (see Figure 1-6).

At the back of the cabinet, pull back on the mounting-bracket flange until the mounting holes align with their respective holes on the back vertical rail.

Install two 10-32 x 0.5-inch flange-head Phillips screws in the back mounting flange to secure the rail assembly to the back vertical rail.

Repeat step 1 through step 5 for the rail assembly on the other side of the rack.

NOTE: Ensure that the rails are mounted at the same vertical position on both

sides of the rack.

Installing the System in the Rack

CAUTION: If you are installing more than one system, install the first system

in the lowest available position in the rack.

CAUTION: Never pull more than one component out of the rack at a time.

CAUTION: Because of the size and weight of the system, never attempt to install

the system in the rack by yourself.

CAUTION: It is recommended that more than one person assist in lifting

the system.

NOTICE: It is recommended that you use a lift table to aid in installing the system

in the rack, particularly if the rail assemblies are more than waist-high.

NOTICE: When you are lifting and installing your system in the rack, avoid grasping

the LCD module on the front of the system as this part is fragile. See Figure 1-7.

NOTE: If you are transporting a system that is already installed in the rack, ensure

that the two rack stabilizer mounting brackets are in place.

• Locate the lower clinch nut holes on either side of the rack just below

the default position for the strain-relief bar.

• To identify the default position of the strain-relief bar and the attachment points

for the stabilizer mounting brackets, see Figure 1-8.

Remove all blades, rear modules, power supplies, and fans before installing your system in the rack.

Lift the system into position to install it in the rack.

It is recommended that more than one person assist in lifting the system.

Guide the system into the rack and lower the system onto the rail assemblies (see Figure 1-7).

Tighten the thumbscrews on the chassis front panel.

Reinstall the blades, rear modules, power supplies, and fans.

Routing and Managing Cables

To provide maximum serviceability and airflow to your system, use the guidelines in the following procedures for routing and managing your system’s cabling configuration. Your system includes the following cable management features:

• A strain-relief bar and Velcro tie wraps, which keep the area directly in back of the system as clear of cables as possible and allow you to move the cable bundles when you need to remove modules (see Figure 1-8).

• An I/O cable enumerator, which maintains the sequence of cables in the order they are connected to the system. Keeping the cable connections intact will facilitate the removal and replacement of I/O modules (see Figure 1-9).

Installing the Strain-Relief Bar

NOTE: Dell recommends that you install the strain-relief bar on the back of your

system and use the Velcro tie wraps with this bar to manage the cables and provide maximum strain relief for all cabling configurations.

NOTE: If you are installing systems in a rack and routing cables from the top of the

rack, install each strain-relief bar in the default position for all systems except the lowest system in the rack. Install the strain-relief bar that ships with that system in one of the U-spaces at the top of the rack to provide cable management by routing from above the installed systems. If you are installing systems and routing cables only from the bottom of the rack, all strain-relief bars should be mounted in their respective default positions. (See Figure 1-8 and Figure 1-9 for examples of cable routing above and below the system.)

Before attaching all cables to the system, locate the strain-relief bar and any corresponding mounting screws that are included with your system (see Figure 1-1 and Figure 1-2).

NOTE: If you are installing the strain-relief bar in the optional position above

your system, you will need two corresponding cage nuts to install on the back of the rail at each attachment point (see Figure 1-8).

On the back of the system on the left and right vertical rails, locate the U-space that is third from the lower edge of your system. Each U-space contains three holes. Install the default strain-relief bar in the tooled top hole of the U-space (clinch nut hole). See Figure 1-8.

Before attaching the cables to their respective connectors, see the instructions in "Connecting and Bundling the Cables" on page 22 and refer to Figure 1-9.

Connecting and Bundling the Cables

NOTICE: Ensure that each bundle of cables that you are connecting cascades over

the strain-relief bar, allowing maximum airflow and serviceability for your system.

Create separate bundles of cables for each logical grouping of a maximum of eight I/O cables or power cables (see Figure 1-9).

Connect the topmost I/O cables, arranging them as they cascade over the strain-relief bar in an ordered row beginning with the top connector in the group (see Figure 1-9).

You can manage and organize your cables following the steps described in "Using the I/O Cable Enumerators" on page 22 before you use the Velcro tie wraps to secure each cable bundle to the strain-relief bar.

NOTE: Figure 1-9 illustrates a fully loaded system configuration. If you are

managing large numbers of cables, consider first identifying each cable group, attaching the enumerators, and then bundling each cable group with the Velcro tie wraps.

Using the I/O Cable Enumerators

Locate the I/O cable enumerators that are included with your system (see Figure 1-1 and Figure 1-2). The purpose of the enumerator is to keep the sequence of cable connectors and their respective cables ordered and intact to facilitate easy removal and replacement of system modules.

For each group of eight cables, select the side numbered one and eight. For a group of 16 cables, you will need two enumerators numbered 1 and 8 and numbered 9 and 16 (see Figure 1-9).

NOTE: Each enumerator is numbered 1 and 8 on one side and 9 and 16

on the opposite side. You will need one enumerator for a set of eight cables and two enumerators for a set of 16 cables.

Orient the enumerator horizontally to attach each of the cascading cables directly above the point of contact with the strain-relief bar (see Figure 1-9).

22 Rack Installation Guide

Locate the three notches on each segment of the enumerator. Each enumerator has the capacity to accommodate a sequence of eight cables in one of three graduated thicknesses of cable fabric. For example, large data cables seat in the largest notch in the segment and small fiber optic cables seat in the smallest notch in the segment (see Figure 1-9).

Identify the cable notch size on the enumerator and seat each cable in the group. Arrange the cables in the same sequence that they connect to the system. (For example, if you have a column of eight cables, seat the topmost cable in the first segment, and so on.) (See Figure 1-9.)

NOTE: Depending on your cabling configuration, you can group and order

the cables in a variety of ways as long as you have no more than eight cables grouped and attached to each enumerator.

Figure 1-9 shows 16 cables grouped and ordered with two enumerators: one with the upper eight cables from both columns and the other with the lower eight cables from both columns. For this same example, you can also group and order each column of eight cables (not shown).

Securing the Cables to the Strain-Relief Bar

Locate the Velcro tie wraps that are included with your system (see Figure 1-1 and Figure 1-2).

Facing the back of the system, position the tie wrap over the cable bundle as it connects with the strain-relief bar (see Figure 1-9).

NOTE: Depending on your system configuration, there are a number of ways

to wrap the cables and secure the cable bundles to the strain-relief bar using the Velcro tie wraps.

To secure the cables to the bar, wrap the cable bundle by passing the tie wrap around the back of the bar, and then wrapping around the cable bundle again, crossing the tie wrap in front of the cables (see Figure 1-9).

The cables should be wrapped securely enough to stay bundled while still able to slide on the strain-relief bar. This step ensures that you can easily move bundles of cable clear of I/O modules during removal and installation.

NOTE: Ensure that you secure all power cables routed from either side of

your system to the strain-relief bar with Velcro tie wraps as shown in Figure 1-9. See the Getting Started Guide for instructions on attaching the power cable retention clip, which adds additional strain relief to your system.
