Hardware installation checklist

These power cables can be coiled. Power cables and ground cables are routed straightly and properly bundled, with sufficient slack at the bend part.

If the cables are fixed on a sharp mechanical part, take protection measures. The lugs and bare wires of power cables and ground cables are tightly wrapped with tubes or insulation tape without any exposed copper wire. Flat washers and spring washers are installed correctly.

A single-mode fiber can only be used with a single-mode optical module while a multimode optical fiber can only be used with a multimode optical module. On most optical modules, the fibers of different types cannot be used together.

The labels of pluggable optical modules are smoothly attached and intact, and cannot be covered by the optical modules. If a short-distance optical fiber is used for a long-distance optical module, especially in loopback scenarios, use an optical attenuator to prevent the optical module from being burnt. Component No. PoE power supply 1 General The proper PoE switch or power adapter is selected, meeting AP power supply and onsite environment requirements.

AP 1 General The AP installation positions comply with the network planning report and APs cannot be installed in environments with strong electrical or magnetic interference or corrosive materials. Signal cable 1 General Routes of signal cables comply with the engineering design document. They are bundled by binding tape with appropriate force. Pigtails can be pulled back and forth easily inside the cable tie and are not bent at a right angle.

Pigtails are not squeezed by other cables or objects. The flange must be fixed. Pigtails are protected with protective tubes or enveloped in troughs when they are routed outside the cabinet.

The protective tubes are bundled and processed to prevent cutting. The optical fiber cannot be folded or twisted, and the pigtail cannot be squeezed. The binding diameter of an optical fiber must be larger than 6 cm. The pigtail connection points must be clean and dustless. Fiber connectors and optical ports that are not used must be protected with protective caps or plugs.

Cleaning must be carried out in strict accordance with Huawei tool specifications. Antenna 1 General The installation positions of antennas should comply with the engineering design and antennas should be securely and reliably installed. The APs or antennas mounted to the same pole should meet the following requirements: The vertical distance should be at least 3.

There should be at least 1 m vertical distance between antennas that work on the same frequency band and belong to different APs. Optical module 1 General A single-mode fiber can only be used with a single-mode optical module while a multimode optical fiber can only be used with a multimode optical module. Independent AC.

The air vent of the device is free from blockage to ensure normal heat dissipation. The power modules are securely installed with their captive screws tightly fixed. AC card. The AC card is correctly inserted into the device slot and secured using the ejector lever. No pins on the backplane are bent when the AC card is installed. The AC is grounded using a ground cable, meeting surge protection requirements. PoE power supply.

Labels must be made for the PoE power cable to identify AP locations. Leave a 20 cm space between PoE power adapters to ensure normal heat dissipation. The PoE switch is correctly grounded with the ground cable. Indoor AP. Outdoor AP. The APs using a metal shell with a ground point must be properly grounded.

Signal cable. Pigtail layout should meet the following requirements: Pigtails are not strained or twisted at the bent parts. The feeder cables shall not be bent or twisted, with no copper wire exposed.

Do not deploy cables overhead between two buildings. There should not be metal subjects within 1 m around an outdoor omnidirectional antenna. Outdoor antenna. Bill of Materials. Design Document. System Boundary. Disaster Recovery Plan. System Design Document. Business Continuity. Disposition Plan.

Also, replace or block any chutes, unnecessary ventilator shafts, mail drops , or slots.

Verify that the room is sealed. This involves not only human security, but the assurance that the vapor barrier is sealed to specifications. In the subfloor void, check perimeter gaps around pipes and conduit, cracks in the deck or walls, expansion joints, open ducts, and walls that connect the subfloor void to the ceiling void or to other floors.

Above the raised floor space, check holes or cracks in the perimeter walls, and gaps around pipes, ducts, doors, and light fixtures. Above the drop ceiling, check for gaps around pipes, ducts, and conduit.

Also, check for breaches around structural beams, inner walls, access doors and ceiling openings to connected attic areas, and roof vents. Clean the room. A complete cleaning of the area should be done to remove all major construction equipment, materials, and debris. Low-grade industrial vacuums can be used to remove heavy deposits, wallboard dust, sawdust, and dirt. Test power.

Load test the generators, UPS, chillers, and other power infrastructure components. Test any devices or connections necessary to ensure that the data center is ready to start online computer operations. Inspect environmental support equipment. Check for proper installation and functioning of all environmental support equipment, such as HVAC. Put the air conditioners and humidifiers through their cycles by adjusting their set points to test cooling, heating, humidifying, and dehumidifying.

Make all necessary adjustments. Filter the room. During and after construction cleaning, the air conditioners should be run continuously to filter the room air. These units need not be set for cooling, but just running to remove particulate matter from the room. Ideally, 60 percent efficiency filters should be used.

Remember to replace these filters before hardware is installed in the area.
