NOTE

When the WDS/Mesh function is enabled on an AP, the blinking frequency of its Wireless indicator indicates the receive signal strength on the WDS/Mesh connection by default. After you connect an AP to a WDS/Mesh network, you can run the wifi-light { signal-strength | traffic } command on the AC to make the Wireless indicator blinking frequency indicate receive signal strength or service traffic rate.

l wifi-light signal-strength:

l If the Mesh function is enabled on the AP, the blinking frequency of the Wireless indicator reflects

the weakest signal strength of all neighboring APs.

l If WDS is enabled on an AP, the blinking frequency of the Wireless indicator reflects the strength

of signals received from a WDS AP.

l If the AP works in leaf mode, the blinking frequency of the Wireless indicator reflects the

strength of signals received from a middle AP.

l If the AP works in middle mode, the blinking frequency of the Wireless indicator reflects the

strength of signals received from a root AP.

l If the AP works in root mode, the blinking frequency of the Wireless indicator reflects the

weakest signal strength of middle APs.

l wifi-light traffic: allows the Wireless indicator to reflect the service traffic volume on the radio.

When an AP functions as a Fat AP, the Wireless indicator of the AP can not reflect the signal strength.

The AP6310SN-GN does not support WDS/Mesh functions; therefore, the Wireless indicator of the AP6310SN-GN does not indicate the signal strength.

1. Check whether the power sourcing equipment supports PoE or is faulty.

2. Check whether the configuration on the power sourcing equipment causes PoE power supply errors, such as the PoE function is disabled or the power-off time range is incorrectly set.

3. Check whether the network cable or distribution frame is faulty.

4. If the device still cannot be powered on, the device itself is faulty. Contact Huawei technical support engineers or Huawei agent and ask them to replace the device.

4.2 An Optical Interface Cannot Turn Up

Fault Description

After an optical interface is connected to a remote device through an optical fiber, its LINK indicator is off.

Possible Causes

l The optical fiber is faulty.

l The optical module on the optical interface cannot meet the requirements.

Issue 12 (2015-08-05) Huawei Proprietary and Confidential

AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xN Hardware Installation and Maintenance Guide 4 Hardware Failures

Troubleshooting Procedure

1. Replace the optical fiber and optical module and check whether the optical interface can turn Up. Ensure that the optical module meets the following requirements.

2. Determine optical module attributes.

l The optical module has passed Huawei certification.

l The transmission speed of the optical module is the same as the interface speed.

l The wavelength of the optical module is the same as that of the remote optical module.

l The transmission distance of the optical module is suitable for the actual distance

between the two devices.

NOTE

l The transmission distance of an optical module is 10 km, 15 km, 20 km, 40 km, or 80 km.

The optical modules with a longer transmission distance have a higher transmit power. If an optical module with a long transmission distance is used for short-distance transmission, the optical interface cannot turn Up because the transmit power is too high. The high transmit power may even burn the receiver of the remote optical module. To reduce the transmit power in this situation, use an optical attenuator between the optical module and optical fiber.

l Optical modules with different speeds are available, for example, 155 Mbit/s, 622 Mbit/s,

and 1.25 Gbit/s. It is recommended that you use an optical module with the same speed as the optical interface to ensure efficient optical transmission.

3. If the interface remains Down, contact Huawei technical support.

5 Appendix

5.1.1 Cable Assembly Precautions

Checking the Appearance of Cables

l If the cable jacket or insulation is visibly dirty, clean it before assembly.

l If the jacket or insulation of a cable has visible damage, irreparable scuffing, or other

defects, do not use the cable.

l If the shield layer of a cable is damaged, do not use the cable.

l If the cable jacket or insulation cracks after the cable is bent or twisted, discard this cable

and check whether other cables have the same problem. If other cables have the same problem, replace these cables.

Checking the Appearance of Connectors

l Do not use connectors with visible defects, damage, rust or scuffing.

l Do not use connectors if their shells or pins have exposed part or uneven plating, or their

pins are lost, broken, or bent.

l Do not use connectors that have dirt on their pins or in their jacks or if there are conductors

between pins or between pins and the shell.

Precautions for Assembly

l Use dedicated tools or tools delivered by Huawei and follow the methods given here during

assembly.

l Hold terminals of cables instead of pulling the cables themselves when installing or

removing cable components.

l Take the following precautions when cutting or stripping cables:

– Make cables slightly longer than necessary.

Issue 12 (2015-08-05) Huawei Proprietary and Confidential

AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xN Hardware Installation and Maintenance Guide

– Coil cables longer than 2 m (6.56 ft) after cutting. Bind and fasten the coils using

bundling ropes. The inner diameters of the coils should be larger than 20 times the outer diameters of the cables.

– When stripping the jackets of cables, avoid damaging the shield layers (braid or

aluminum foil), insulation, core conductors, and other jackets that do not need to be stripped.

– After assembling cables, cut all visible cross sections of jackets to ensure that the cross

sections are arranged neatly.

– Do not touch the core conductors of cables with your hands. Terminate exposed

conductors in a timely way after stripping off insulation so that the surface of the conductors does not become oxidized.

l Take the following precautions when crimping and connecting cables or connectors:

– The terminals and conductors should be connected tightly after they are crimped. They

should not be moved or turned.

– Cut all the exposed copper wires.

– Try to avoid a second crimping of sleeves.

– Keep all the conductors clean and aligned.

Checking the Appearance of Contact Strips

Context

l To ensure proper contact between the crimped wires and the wire conductors, the heights

and sizes of the contact strips must be standard and the same.

l The contact strips must be parallel to each other, with an offset of less than ± 5°. The top

margin of a strip must be parallel to the axis of the connector, with an offset of less than ± 10°.

l To ensure conductivity, the surface of the contact strips must be clean.

l The contact strips must be in good contact with the RJ45 socket. The plastic separators

must remain intact and be aligned.

l The contact strip blade must extend beyond the ends of the wires. The ends of the wires

must be in contact with the edge of the RJ45. The distance between them must be less than

0.5 mm (0.02 in.).

Procedure

Step 1 Hold the crimped connector, with the front side facing you, and check whether the contact strips

are of the same height. The height should be 6.02 ± 0.13 mm (0.237 ± 0.005). If a measuring tool is not available, you can compare the connector with a standard connector. Figure 5-32 shows an unqualified piece, and Figure 5-33 shows a qualified piece.

Testing the Connection of Assembled Cables

Context

Huawei provides two types of Ethernet cables: straight-through cables and crossover cables.

l Straight-through cables are connected in a one-to-one manner. They are used to connect

terminals such as a computer or switch to network devices. Table 5-7 lists the connections of core wires in a straight-through cable.

Procedure

Step 1 Feed both connectors of the cable into the ports of the cable tester.

Step 2 After the connectors are properly inserted, turn on the tester. If the indicators from 1 to G turn

on simultaneously, you can infer that the pins work normally and the wires are correctly connected.

NOTE

Turn the switch to the S position to slow down lighting of the indicators so that you can see the indicators more clearly, as shown in Figure 5-39.

Figure 5-39 Testing the conduction and connections of wires

Step 3 Gently shake the connector and repeat Step 2 to check whether the metal contact strips are in

good contact with the core wires and Ethernet ports, as shown in Figure 5-40.

Figure 5-40 Checking the reliability

The procedure for testing a crossover cable is the same as that for testing a straight-through cable except for the sequence in which the indicators turn on, which depends on the wire connections of a crossover cable.

The Ethernet cable is qualified if the indicators turn on in the following sequence:

At the master (left) section of the tester, the indicators turn on in the sequence of 1-8-G. At the slave (right) section of the tester, the indicators turn on in the sequence of 3-6-1-4-5-2-7-8-G.

If the indicators do not come on in this sequence, the Ethernet cable is unqualified.

NOTE

If a tester is not available, you can use a multimeter to perform a simple test, as shown in Figure 5-41.

5.1.4 Installing Cable Accessories

Precautions for Installing Cable Accessories

Tools

NOTE

The illustrations in this document may differ from actual situations, but the installation methods are the same. For example, in this document, the adapters of cable connectors have separate interfaces. In the actual situation, the adapters may have interfaces fixed on equipment.

Use dedicated tools provided or specified by Huawei and follow the installation procedure described here.

5 Appendix

Bending Radius

Unless otherwise specified, bending radius (R) of cables or fibers must meet the requirements listed in Table 5-9.

Table 5-9 Bending radius of cables or fibers

Cable or Fiber Bending Radius (R)

Ordinary cable

Fiber

NOTE

The letter d indicates the diameter of a cable or fiber.

Precautions for Installation

l Hold terminals of cables instead of pulling the cables themselves when installing or

removing cable components.

In normal cases, R ≥ 2d. When the cable is connected with a connector, R ≥ 5d.

R ≥ 40 mm (1.57 in.); Bending angle > 90°

l Do not insert a connector forcibly when the connector is blocked. Use a dedicated tool to

pull out the connector. Install the connector again after you check that the pins are inserted properly.

l Before tightening screws on cable connectors, ensure that the connectors are properly

connected to their adapters. Tighten the screw with appropriate force using a flat-head or Phillips screwdriver instead of bare hands or an electric screwdriver. If the screw cannot be screwed into the tapped hole, determine the reason and try again. Do not apply too much force, or the screw or adapter may be damaged.

Issue 12 (2015-08-05) Huawei Proprietary and Confidential

AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xN Hardware Installation and Maintenance Guide

l When removing densely aligned cables or fiber connectors, use dedicated pliers such as

cable-pulling pliers and fiber-pulling pliers.

l Do not twist, bend, stretch, or extrude fibers during installation.

l Cover the idle fiber connectors with dust caps. Remove the dust caps before using the fiber

connectors.

Requirements for Cable Routing

l To protect cables, remove the burrs in the cable through-holes or install protective rings in

the holes.

l To ease the connection and to avoid stress, keep cable joints slack. After connecting

multiple cables to a connector that has multiple interfaces, keep the cables slack to avoid generating stress.

l Bind or clean cables gently because cable distortion affects signal quality.

l Keep cables away from moveable components such as doors.

l Sharp objects must not touch cable wiring to prevent damage to cables.

l To protect power cables, route power cables of the active and standby power modules

separately.

5.2 Environmental Requirements for Device Operation

5.2.1 Environmental Requirements for an Equipment Room

Requirements for Selecting a Site for an Equipment Room

When designing a project, consider the communication network planning and technical requirements of the equipment. Also consider hydrographic, geological, seismic, power supply, and transportation factors.

Construction, structure, heating and ventilation, power supply, lighting and fire-proof construction of the equipment room should be designed by specialized construction designers to suit the environmental requirements of devices. The equipment room should also follow local regulations concerning the industrial construction, environmental protection, fire safety, and civil air defense. Construction must conform to government standards, regulations, and other requirements.

The equipment room should be located in a place free from high temperature, dust, toxic gases, explosive materials, or unstable voltage. Keep the equipment room away from significant vibrations or loud noises, as well as power transformer stations.

The specific requirements for selecting a site for an equipment room are as follows:

l The room should be located at a distance of at least 5 km (3.11 mi.) from heavy pollution

sources such as smelting and coal mines. It should be located at a distance of at least 3.7 km (2.30 mi.) from moderate pollution sources such as chemical, rubber, and galvanization factories. It should be located at a distance of at least 2 km (1.24 mi.) from light pollution sources such as packinghouses and tanyards. If these pollution sources cannot be avoided, ensure that the equipment room is upwind of the pollution sources. In addition, use a highquality equipment room or protection products.

l The room should be located away from livestock farms, or be upwind of the livestock farms.

Do not use an old livestock room or fertilizer warehouse as the equipment room.

l The equipment room must be far away from residential areas. An equipment room that is

not far away from residential areas must comply with equipment room construction standards to avoid noise pollution.

l The room should be located far away from industrial and heating boilers.

l The room should be at least 3.7 km (2.30 mi.) away from the seaside or salt lake. Otherwise,

the equipment room should be airtight with cooling facilities. In addition, alkalized soil cannot be used as the construction material. Otherwise, equipment suitable for wet conditions must be used.

l The doors and windows of the equipment room must be kept closed to maintain an airtight

room.

l Using steel doors to ensure sound insulation is recommended.

l No cracks or openings are allowed on the walls or floors. The outlet holes on the walls or

windows must be sealed. Walls must be constructed such that they are smooth, wear-

resistant, dustproof, flame retardant, sound insulated, heat absorptive, and have electromagnetic shielding.

l The air vent of the room should be far from the exhaust of city waste pipes, big cesspools

and sewage treatment tanks. The room should be in the positive pressure state to prevent corrosive gases from entering the equipment room and corroding components and circuit boards.

l It is recommended that the room be on or above the second floor. If this requirement cannot

be met, the ground for equipment installation in the room should be at least 600 mm (23.62 in,) above the maximum flood level.

l The equipment room should be strong enough to resist winds and downpours.

l The room should be located away from dusty roads or sand. If this is unavoidable, the doors

and windows of the equipment room must not face pollution sources.

l Do not place air conditioning vents near the equipment so that they blow directly on the

equipment because condensation may be blown into the equipment.

l Do not use decorative materials that contain sulfur in the equipment room.

Equipment Room Layout

5 Appendix

An equipment room usually contains mobile switching equipment, telecommunications equipment, power supply equipment, and other auxiliary equipment. To ensure easy maintenance and management, place the equipment in different rooms. Figure 5-79 shows the layout of the equipment room.
