Other personnel requirements shall be established by Owner.

4 Operation of systems

The requirements presented in this section shall be met by the Customer.

Server Space Requirements

Use of process room by other services

In the room where electronic computing, telecommunication and passive switching equipment are located, auxiliary services of the building (boiler rooms, terminals, sanitary units, storage rooms) must not be located, which can interfere with the operation of electronic systems. It is not possible to use the specified room for storage of auxiliary equipment (buckets, detergents, etc.), especially combustible and flammable materials.

Floor requirements

The rooms shall have dust protection measures. Clean floors shall be laid on a non-combustible base (cement, sand bracing, etc.). The floors shall be smooth, flawless, easy to clean and capable of wet cleaning.

To prevent the occurrence of static electricity, the floor cover must have antistatic properties.

Standard load on ceilings in process rooms is regulated in accordance with SNiP 2.01.0785 * and should be at least 300 kgf/m2. When installing process equipment in existing rooms, when there is no data on the load capacity of the floor, it is necessary to check the load capacity for its adequacy, depending on the location of the designed

Fire protection measures

Equipment of process rooms shall be provided with fire and security alarm systems.

To prevent equipment damage from water, "dry" fire extinguishing systems shall be provided.

Installed fire protection means shall be protected against accidental activation (actuation) by mesh screens.

Design and placement of ventilation equipment, actuators and articles, materials used shall correspond to categories and groups of moved gas-air mixtures according to PUE and categories of serviced rooms.

To prevent the spread of smoke and overflow of gas-air mixtures, ventilation systems are equipped with fire-retarding and check valves.

Places of passage of air ducts

through walls, partitions and floors are sealed with non-combustible materials, providing a normalized fire resistance limit of the crossed fence.

5 Grounding Requirements

The presence of UPS, i.e. equipment that operates when voltage is reduced, in accordance with the chapter 54 of part 5 of GOST R 50571.1597 (IEC 36455480) unambiguously implies the mandatory presence of an additional grounding conductor that is not electrically connected to other grounded metal parts.

The requirement to have an additional earthing conductor also does not contradict the requirements of the international IEC Standard 364554896.

By the beginning of the Contractor's work on the installation of the power distribution network in the building by the Customer, work should be carried out to create an additional grounding conductor in accordance with the requirements of the relevant GOST and taking into account local climatic conditions. The use of an additional grounding conductor for operation is possible if there are acceptance test reports (in accordance with RD 34.20.50195).

The grounding shall be carried out in accordance with the basic requirements and recommendations of TIA/EIA607 standard for grounding in cross and server rooms.

The telecommunication grounding circuit is connected to the main one in the immediate vicinity of the zero conductor and/or grounding electrode system into the building. The network equipment in the server should be connected to the power supply network through sockets with grounding contacts, the latter being connected to the main grounding circuit. Grounding contact-stroke of plug is galvanically connected to housing of network equipment. Due to this, the telecommunication grounding circuit can have additional connections to the main one and work in parallel with it.

The use of the telecommunication circuit guarantees reliable grounding of the network equipment regardless of the state of the main grounding circuit.

The telecommunication grounding circuit consists of:

several grounding plates, one of which is the main one;

main and inter-trunk grounding bars;

busbars for connection to the main grounding system.

All conductors and flexible buses used in the telecommunication grounding circuit shall be made of copper, shall have insulation and a section of not less than 6 AWG (diameter 4.12 mm, cross section area 13.3 mm2). The general rule applied to the section selection of these conductors is that the resistance between the ground points should not exceed 1 ohm. All connections of grounding plates with main busbars are made by welding.

The main ground plate is designed to connect the main ground bars, the main ground bus and the adjacent network equipment. In addition, all passing metal structures of cable channels - pipes, trays and so on - must be connected to it. Structurally, the main ground plate is a metal plate with a thickness of at least 6 mm and a minimum width of 100 mm. The length of the plate is determined by local conditions. It is equipped with holes for attachment to building structural elements and for connection of grounding conductors of network equipment (for example, using a screw clamp).

The choice of the location of the main ground plate is determined by the compromise between the desire to bring it closer to the place of entry into the building of external trunk telecommunication cables and minimizing the length of the bus connection to the main ground system.

If possible, the main ground plate is connected to the nearest and well-grounded metal structures of the building.

Earthing plates are located in the server room. They are connected to the main grounding buses and are designed for connection of grounding conductors of network equipment, installation cabinets, as well as metal structures of cable channels.

Structurally, the ground plate is similar to the main plate, only its minimum width should be at least 50 mm.

Desirably, one or more ground plates are connected to adjacent and well grounded metal structures of the building.

The grounding backbones connect the grounding plates in the server with the main grounding plate. Several ground plates located in different cross-country lines can be connected to one main bus.

The water pipe system of the building cannot be used as grounding lines.

The connection bus to the main grounding system connects the main grounding plate to the main grounding system of the building. Its cross section must be not less than that of the main grounding bars. The connection should be made directly to the conductor to the system of buried electrodes having good electrical contact with the ground and/or to the conductor with zero phase from the external power supply network of the building.

Standard EN 50173 requires that the potential difference between the two earthing connection points does not exceed 1V .

6 Environmental protection

Due to the fact that the equipment designed for the installation does not have a harmful impact on the environment, sanitary and protective measures are not provided for by this working project.

The specifications for the equipment of the switches designed for installation and the software do not normalize the noise levels, since the equipment does not contain mechanical units and units that can be noise sources.

The equipment envisaged by the design does not belong to the category of radio-emitting devices.

7 Fire-fighting measures

This project is performed in accordance with the current norms and rules for compliance with measures ensuring fire and explosion safety during operation of the designed equipment.

Fire safety in the building is provided by fire extinguishing equipment, as well as:

- placement of equipment in rooms taking into account necessary evacuation passages for maintenance personnel;

- grounding of the designed equipment and metal parts of the conduits;

- using cables with non-combustible containment;

- presence of fire alarm.

9 Engineering and technical measures of civil defense. Emergency prevention activities

The following emergency prevention measures are implemented in the working project:

- all equipment is certified, does not contain sources that have an impact on

human health and changes in the sanitary and hygienic situation in the construction area;

- when placing equipment, all requirements of regulatory documents for its placement, electrical safety, explosions and fire safety are implemented.

During the introduction of a state of emergency (disaster, natural disaster, major accident, epidemic, etc.), communication services should be provided to state authorities on conditions determined by the current legislation of the Russian Federation
