Precautions

Following All Safety PrecautionsBefore any operation, read the instructions and precautions in this document carefully to minimize the possibility of accidents.The Danger, Caution, and Note items in this document do not cover all the safety precautions that must be observed. They provide only the generic safety precautions for operations.When operating Huawei products and equipment, you must comply with safety precautions and special safety instructions relevant to the corresponding equipment provided by Huawei. The safety precautions in this document are relevant only to Huawei products. Huawei is not liable for any consequence that results from violation of universal regulations for safety operations and safety codes on design, production, and equipment use.

Complying with Local Safety RegulationsWhen operating the product or equipment, comply with local safety regulations.

Qualified Personnel OnlyInstallation and maintenance personnel must be trained to perform operations correctly and safely.

Personnel SafetyThe high-voltage power supply provides power for running the system. Avoid direct contact with the high-voltage power supply or contact through damp objects. Failure to do so causes serious injury or death.Non-standard and incorrect operations on the high-voltage power supply may result in fire and electric shock.Do not perform operations on high-voltage and AC power supply facilities or on a tower or mast in the case of thunderstorm. Failure to do so causes serious injury or death.Ground the device before powering it on. Failure to do so causes damage to the device or personal injury.Power off the device before performing operations on the power supply facilities.

Personnel SafetyHigh power radio-frequency signals are harmful to the human body. Ensure that the transmitter antennas are muted before installing or maintaining an antenna on a tower or mast that holds a large number of transmitter antennas.Do not stand close to, or look into the optical fiber outlet without eye protection when handling optical fibers.Take preventive measures when drilling holes. Otherwise, dust may hurt your eyes or you may inhale the dust.Power off the batteries before connecting the cables to the batteries. Failure to do so causes personal injury.When working at heights, be cautious about falling objects.

Device SafetyCheck the electrical connection of the device before operation and ensure that the device is securely grounded.The static electricity discharged from the human body may damage the electrostatic sensitive components, such as large-scale integrated circuits (LSIs), on the circuit board. Wear an ESD wrist strap or ESD gloves when handling a circuit board.

2

Do not hold a board without hand protection. Wear an ESD wrist strip or ESD gloves before handling a board.

Insert filler panels into vacant slots on an NE to prevent foreign matters from getting into the NE, which may result in faults on the NE.Boards are fragile and valuable. When handling or placing a board, exercise caution and put it into a dedicated packing box.

Holding a board without hand protectionWearing ESD gloves Wearing an ESD strip

Hold the front panel of a board with hands.

Installing the Assemblies

1 Installing the RTN 950A

When installing the RTN 950A, ensure that the fan assembly is installed in the lower part of the cabinet. When being installed in the AC or DC powered OMB cabinet, the RTN 950A can work as only a repeater. When using service cables such as E1 cables and Ethernet cables, install the RTN 950A in the APM30H or TMC11H cabinet.

Installing the PGND Cables for the RTN 950Ab

The ground cables and signal cables must be bound separately or must be separated from each other for certain spacing to minimize mutual interference.

The PGND cables are in yellow-green color. The general ground cable has a cross-sectional area of 16 mm2.

1 Checking Cabinet Installation

Checking the Installation

2 Checking Installation Environment

No. What to Check For

1 No fingerprints or other smears exist on the exterior of the equipment cabinet.

2 No excessive adhesive tapes or cable ties exist on the cables.

3 No tapes, cable ties, wastepaper, or packing bags are left around the equipment cabinet.

4 All the items around the equipment are neat, clean, and intact.

No. What to Check For

1 The layout of the cabinet complies with the engineering designs.

2 In pole-mounting mode, the mounting brackets are fixed securely, and the frame is fixed properly and is not distorted.

3 In wall-mounting mode, the holes for the frame are in proper contact with the holes for the expansion bolt, and the frame and the wall surface are in proper horizontal contact.

4 In wall-mounting mode, the cabinet is installed securely and does not swing when you shake it.

5 The waterproof cover of the bottom port and the hang chains are bound with the surrounding cables.

6 The surface of the overall equipment is clean and tidy. The exterior paint is intact.

7 The door and lock of the cabinet are proper.

8 All labels, tags, and nameplates are correct, legible, and complete.

21

3 Checking Electrical Connections of the Cabinet

No. What to Check For

1 All the self-made PGND cables are copper-based with proper wire diameters. There is no switch, fuse, or short circuit on the cable.

2 According to the wiring diagram of the power system, the PGND cables are connected securely, the AC lead-in cables and cables inside the cabinet are connected properly, and the screws are tightened. Ensure that the output and input cables are not short-circuited.

3 The redundant part of the power cable or PGND cable is stripped off rather than being coiled.

4 The lugs at both ends of the power cable or PGND cable are soldered or crimped securely.

5 Bare wires and lug handles at the wiring terminals are wrapped tightly by using insulation tapes or heat shrink tubes.

6 The flat washers and spring washers are mounted securely to all the wiring terminals.

7 The connectors of all cables are securely linked, especially those at the bottom of the cabinet.

8 The cables are properly bound. Cable ties are installed at equal spacing and in the same direction.

9 The power cable and PGND cable are routed separately from other cables.

10 The cable layout facilitates maintenance and expansion in the future.

11 The labels at both ends of each cable are legible.

12 The excess of cable ties is trimmed off without remaining rough edges.
