2.3 Unpacking the Equipment

Before unpacking the carton, ensure that the packing carton is intact and not damaged or soaked. If the equipment is found eroded or damped, stop unpacking, check for the reason, and contact the supplier.

Check items in the carton against the packing list (included in the Quick Start Guide) and ensure that all items listed in the packing list are included in the shipment. If the quantity of the goods is inconsistent with the packing list, contact the supplier or agent.

Usually, the packing list contains the following items.

l Remote radio unit

l Screws (including the plastic expansion tubes)

l Quick Start Guide

l Warranty card

l MAC address label

l SN label

NOTE

If a PoE adapter is required, you need to purchase it separately.

2.4 Determining the Installation Position

voltage, much vibrations, or strong noise, or in places near flammable or explosive

Issue 01 (2015-12-12) Huawei Proprietary and Confidential

R230D Hardware Installation and Maintenance Guide

materials and interference sources such as a large radar station, radio station, and transformer station.

l Install the device in a site that is free from leaking or dripping water, heavy dew, and

humidity, and take protective measures to prevent water from flowing into the equipment along the cable.

l Place the AP far away from electronic devices that may produce radio interference, such

as microwave ovens, antennas, and other radio communication devices. For details, see

Table 2-2.

l Install the device in hidden places and ensure that the device do not disturb daily work

and life of residents.

l Make the engineering design by fully considering such factors as hydrology, geology,

earthquake, electric power, and traffic. The selected site should comply with the environment design specifications of communications equipment.

4 Hardware Failures

4.1 An device Fails to Be Powered On

Fault Description

4 Hardware Failures

The SYS indicator of a device is off.

Possible Causes

l The power sourcing equipment does not support the PoE function or is faulty.

l The power sourcing equipment is incorrectly configured (the PoE function is disabled or

the power-off time range is improperly set).

l The line is faulty (the network cable or distribution frame is damaged).

l The device is faulty.

Troubleshooting Procedure

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.

5.1 On-site Cable Assembly and Installation

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.

– 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.

Issue 01 (2015-12-12) Huawei Proprietary and Confidential

R230D Hardware Installation and Maintenance Guide

– 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.

NOTE

The connectors, cables, and tools provided by different vendors may be different. The figures in this document are for your reference only.

Step 3 Put the OT terminal B onto the exposed conductor, and ensure that the OT terminal is in good

contact with the insulation coating C, as shown in Figure 5-3.

NOTICE

After the conductor is fed into the OT terminal, the protruding part of the conductor, or L2 in

Figure 5-3, must not be longer than 2 mm (0.08 in.).

Step 4 Crimp the joint parts of the bare crimping terminal and the conductor, as shown in Figure 5-4.

NOTE

The shapes of crimped parts may vary with the crimping dies.
