Precautions

NOTE

Bundling cables

CAUTION

This document provides simple and distinctive guidelines for quick hardware installation of the PTN 950.

This document does not describe pre-delivery assembly. This document only describes procedures for onsite

installation.

Electrostatic Discharge

Always wear an anti-static ESD wrist strap when handling the equipment or sensitive components to prevent

electrostatic discharge causing possible bodily injury or damage to the equipment or sensitive components. Ensure

that the other end of the ESD wrist strap is properly grounded.

Binding intervals between cable ties or optical fiber binding straps inside the cabinet cannot exceed 250 mm.

(Binding intervals cannot exceed 200 mm for user cables).

Binding intervals between cable ties for all cables and corrugated pipes outside the cabinet are determined based on

the distance between the two horizontal beams. If the cable trough does not contain any beams, the binding intervals

between cable ties cannot exceed 250 mm.

Verify that the equipment room, power supply, ground cables and optical cables are ready for installation. Start the

installation according to the engineering design documents after confirming that conditions are met. Refer to the

Installation Guide for information about specific operational requirements and technical specifications.

Pre-Installation Check

CAUTION

The PTN 950 supports indoor and outdoor installation. Ensure that the requirements on device operating

environments are met before installation. Using the outdoor cabinets IMB network box, APM30H, and R01S200 can

moderately improve the device operating environments. You can use the ETP4830 external AC power system to

supply power to the network boxes and outdoor cabinets. If you need to use an outdoor cabinet other than the IMB

network box, APM30H, and R01S200 for the PTN 950, contact Huawei to determine whether the outdoor cabinet

meets requirements of Huawei devices on the device operating environments.

The PTN 950 is available in two models: common chassis and extended chassis, which are 2 U and 3 U

high, respectively. Installation modes of the two types of chassis are basically the same; therefore, the

common chassis is used as an example to describe the installation of the PTN 950 in this document. For

information about the installation of the extended chassis, refer to the Appendix.

bInstalling the PGND cable

Introduction to the cable guiding frame Fixing the floating nuts

Mark the positions where floating nuts are to be

installed, and install four floating nuts on both sides of

the rack.

2. Place the chassis's

mounting ears and

cabling rack U-shaped

slots over the screws,

tighten the screws at the

bottom.

1.Hang the screws of

the mounting ears on

the chassis to the rack

loosely.

3. use screws to tighten

the top of the chassis.

1. Remove one screw for installing PGND cable before

installing the chassis in the cabinet.

In the scenario where the chassis is installed in an

ETSI cabinet, on the wall, or on the desk, install

the PGND cable onto the grounding point on the

left side of the chassis.

If the PGND cable is installed in the19-inch cabinet,

connect the PGND cable to the grounding point of

the left mounting ear of the chassis.

Make a proper terminal for the power cable end

according to the electrical power cable processing

specifications. Then, insert the power cable in the

DC connector according to the wiring sequence.

When installing or routing cables, refer to the engineering document on site to install and connect the power cable

at the opposite end.

0.22±0.03 N·M

It is recommended that one circuit breaker (fuse) in the power distribution cabinet corresponds to one set of equipment

(subrack). That is, one circuit breaker in the power distribution cabinet outputs one channel of power supply, which is

provided to only one set of equipment instead of multiple sets of equipment. If one circuit breaker in the power

distribution cabinet corresponds to multiple sets of equipment, when overcurrent occurs on one set of equipment, the

circuit breaker may perform the protection operation. Hence, the power of multiple sets of equipment fails.

The working current of the fuse on the power distribution cabinet may be affected by certain factors such as

temperature. Hence, derating should be adopted during design of power distribution.
