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"

- 16 lag bolts as shown in Figure 2-4.
