Introduction

The system rack is an attractive enclosure designed to store and protect your server components. The system rack allows you to integrate your server, monitor, and other components in one cabinet that may be installed in a limited amount of floor space in just about any location. Removable side walls and front and rear doors ensure easy access to all installed components, while a special locking system prevents unauthorized access.

System Rack Models

The system rack is available in three models: 42U, 36U and 27U. The only difference in the three models is the height of the rack. The size of each system rack is as follows:

Model 42U –

Model 36U – 18

Model 27U – 14

This guide contains the information necessary to install the 42U System Rack. The installation process for the 36U and 27U is similar to the 42U model.

Grounding Requirements

Equipment Location

When planning your facilities, the following guidelines must be considered:

Does the allocated space allow for the proper installation of the

equipment and the performance of operation and maintenance activities?

Are the environmental conditions suitable for reliable operation?

Is the construction of the floor appropriate for the weight of the

equipment being installed?

Will the air conditioning maintain adequate temperature and humidity

conditions for the equipment being installed?

Are the proper electrical facilities available and adequate for the

equipment being installed?

Will future expansion be necessary or possible?

To plan your facilities, you must know your system configuration.

Space Requirements

The system rack requires an area that can:

Accommodate the height of the cabinet, which is 78.7 inches, (2 meters).

Provide a clearance above the rack of 16 inches (400 mm).

The space requirements of the area surrounding a single cabinet are given in Figure 2-1. Note that the overall width should be increased by 23.4 inches for each additional cabinet that is required by your system.

Environmental Conditions

The location should be examined for the following environmental hazards:

Dust - floating dust must be kept to no more than 0.3 mg/m3. Dust should

be held to less than 0.15 mg/m

Radio Frequency (RF) - Normally, there is no need to worry about the

effect of radio frequency interference on computer operations. In areas where strong waves are generated or where a high-frequency device is installed on the same floor as the server, radio frequency can affect the functionality of the system.

Magnetic Fields (MF) - Normally, there is no need to worry about the

effect of magnetic fields on computer operations. If the server is installed near cables or transformers that permit the flow of high currents, functionality can be affected.

Floor Construction

(

)

Aspects of floor construction, such as load capacity and construction materials, must be considered when installing one or more rack systems.

Note:

Use Table 2-1 to calculate the load that each rack of your system configuration places on the floor.

The rack supports up to 551.2 lbs. (250 kg).

Planning Your Site 2-5

If you do not know the load capacity of your flooring, consult your building manager or an architect.

In many instances the equipment is installed directly on the existing floor and interconnecting power cables are protected by cable covers.

In other instances, raised floors – that form a double floor – are used. Some advantages of raised floors are:

Interconnecting cables can be routed under the raised floor.

Floorboards can be easily removed to facilitate installation of cables.

Adjustments can be made to air-conditioning ducts by cutting the floor as

required.

The height of the raised floor must be no less than 14 inches (350 mm) — at least 16 inches (400 mm) is recommended. The base floor must be dustproof to prevent it from producing dust due to weathering and the floor covering material should produce little dust.

If a raised floor is used, continuity must be provided between the floorboards and support pillars. The insulation resistance between the floor surface and support pillars must be within the range of 106 to 1010 ohms.

To prevent the build-up of static, an antistatic treatment can be applied to the floor to keep its surface insulation resistance to at least 106 to 1010 ohms. Do not expose any metal directly to the floor.

When the surface insulation resistance is large, antistatic liquid can be applied or an antistatic mat can be used to eliminate any static charge.

If you are going to install your system on a carpet in an ordinary business office, use an antistatic carpet that produces little dust.

2-6 Planning Your Site

System Rack Placement

The system rack comes equipped with a front stabilizer that:

steadies the rack when you extend equipment for servicing, and

prevents creeping due to vibration.

The stabilizer is predrilled to allow you to secure the system rack to the floor.

Note:

If preparing the area prior to the arrival of the system, review the power cable restrictions given in “Electrical Facilities” before setting any stabilizer anchors.

Figure 2-2 gives the distance between anchoring holes when the stabilizer is attached to the system rack.

Planning Your Site 2-7

Figure 2-2. Distance Between Stabilizer Anchors

If the rack is installed on a concrete floor, you can bolt the rack to the floor using 3/8" concrete drop-in anchors and 1½"-16 bolts.

If you are installing your rack in an area with a raised floor, you can use concrete drop-in anchors and 3/8"-16 threaded rod with washers and nuts to secure the rack to the concrete beneath the raised floor. See Figure 2-3.

Figure 2-3. Raised Floor Installation

When you are installing your system on a wooden floor, you can use 1-3/4" 3/8"

Figure 2-4. Wooden Floor Installation

Air Conditioning

A properly sized air conditioning system ensures stable and reliable operation of your servers by performing the following tasks:

cooling the system

preventing the generation of static charges

preventing the formation of corrosion causing condensation within the

system.

The system rack’s temperature and humidity requirements are listed in Table 2-2.

Table 2-2. Temperature and Humidity Requirements

Item

Temperature 16 - 30°C 0 - 45°C

Relative humidity 40 - 70%

Temperature and humidity should be measured 19.5 inches (50cm) from the system and 3.3 ft (1m) above the floor.

To satisfy temperature and humidity requirements, an air conditioner should be capable of heating, humidifying, and dehumidifying.

Heat is needed to precisely control temperature, increase computer room temperature in winter to the system’s operating conditions, and to control humidity.

Humidifying is required to combat low humidity, which allows static charges to build-up.

If the system is operated in high-humidity conditions where condensation can occur, long term reliability may be affected.

Cooling Capacity

Operating Non-operating

10 - 80%

(non-condensing)

The cooling capacity of an air conditioner is determined by the following factors:

90% of the total calorific value of the system (allowing for expansion)

calorific value from the ceiling, walls, and windows

calorific value generated by personnel

calorific value of lighting and additional machines

humidity control effects.

Planning Your Site 2-9

The air conditioner’s capacity must be larger than the sum of the above items. Use Table 2-3 to calculate calorific values – in BTUs.

Electrical Facilities

Depending on whether data availability is critical to your application or not, when you configured your system, you chose either an uninterruptible power source or a power distribution unit to supply rack components with AC power. The AC supply lines required by each of these devices is specified in the following paragraphs.

Uninterruptible Power Source (UPS)

If you have purchased one or more UPSs to supply AC power to your system and your system is located in North America, each UPS requires a 3-wire 30-Amp single-phase 120 Volt receptacle within six feet of the rear of the system rack. The UPS power cord comes equipped with a NEMA L5-30P power connector.

Equals

Installed

If your system is located in Europe, it requires a 240 Volt receptacle. The UPS power cord comes equipped with an IEC-320-C20 power connector.

Power Distribution Unit (PDU)

If you have purchased one or more PDUs, each PDU requires a 3-wire 30-Amp single-phase 120 Volt (240 Volt in Europe) receptacle within 10 feet of the rear of the system rack. The UPS power cord comes equipped with a NEMA L5-30P power connector (US models).

2-10 Planning Your Site

Grounding Requirements

The system rack must have a dedicated ground attached to the power distribution panel.

The ground wire must have an earth resistance of 100 ohms or less and depending on your local electrical code, a thickness of 38 mm2 or more.

A grounding cable (12 gauge) that attaches the rack to frame (earth) ground must be used.

For safety reasons, ground connections are necessary for both power distribution systems and air conditioners.

If it happens that the ground to the server and the safety ground must be shared, branch it near the grounding electrode.

If a building structure such as a steel frame is used as a grounding electrode, use the main structural member closest to the building foundation.

This chapter helps you configure your system and determine the number of racks you will need for your system.

When planning your configuration, you should consider the following guidelines:

Does the layout violate any cable constraints?

Is there enough rack space to accommodate all of the equipment that I

have?

Cabling Constraints

When planning your system configuration you must consider the length of the cables that interconnect system components.

If a Server without any additional options meets all of your current computing needs, you will only have to concern yourself with connections to your keyboard, mouse, monitor and your LAN.

However, reviewing all the information in this section will allow you to configure your rack with future expansion in mind.

Configuration Guidelines

When you configure a system, you should check your configuration to ensure compliance with the following guidelines:

To improve rack stability when servicing system components, mount heavier items such as servers in the bottom of the rack. If your rack is a stand-alone unit and the rack is more than 75% filled with components, consider installing the optional side stabilizer kit.

Each Model 42U Rack can contain up to 42U of components (1U is equal to

1.75 inches). Models 36U and 27U contain up to 36U and 27U of components, respectively.

The maximum Volt/Amps available from a single UPS is 3000VA (2250W).

The maximum Volt/Amps available from a single PDU is 2880VA.

The UPS should always be installed in the bottom of the rack.

The UPS and its associated PowerChute® plus software can only support three servers per UPS, without purchasing an additional interface expander module and additional cables.

If power distribution is provided by a PDU, the PDU is normally installed in the bottom of the rack. However, when rack space is at a premium, you can install the PDU directly behind the keyboard tray or the monitor tray.

The keyboard can be no more than 5U from the BSU unless a concentrator or extension cables are purchased.

If you are configuring the keyboard for use in a standing position, the recommended height is 18 to 20 U.

The System Rack Configuration Worksheet, Table 3-3, may be used to calculate the space requirements for components you plan on installing into the rack.

Planning Your System Rack Configuration 3-7

Calculating Load and Determining UPS On-Battery Run Time

When you have chosen your configuration, you can use Table 3-4 and Table 3-5 to determine the load on a single power source and how much run time your configuration can expect from your UPS in the event your main AC service is interrupted.

To calculate the load and your on-battery run time, perform the following steps:

Determine the total load placed on each power source. The maximum load you can place on a single power source is:

Source Maximum Load

UPS 3000VA (2250W)

PDU 2880VA

Table 3-4 provides Volt/Amp load values of system components and provides space to include other options.

You can calculate Volt/Amps by multiplying a component’s voltage by its current requirement.



Voltage * Amps = VA

Or if your component’s power requirement is expressed in watts, multiply its wattage rating by 1.4.



Watts * 1.4 = VA
