Precautions
This document provides quick guidelines for hardw ware
installation. This document does not describe pre-delivery ass
sembly. This document describes only procedures for onsite
installation.
Electrostatic Discharge ontact Wear ESD gloves or an ESD wrist
strap prior to co with the equipment or before handling the
plug-boards, boards, and IC chips to prevent damage to sensitive
components caused by electrostatic discharge from the human body.
Ensure that the other end of the ESD D wrist strap is properly
grounded. IC
Binding Cables Binding intervals between cable ties or optical
fibe er binding straps inside the cabinet cannot exceed 250 mm.
(The distance cannot exceed 200 mm for user cab bles). /250mm 200mm
Binding intervals between cable ties for all cables and corrugated
pipes outside the cabinet are determined according to the distance
between the two horizon ntal beams beams. If the cable trough does
not contain any beams beams, the binding intervals between cable
ties cannot ex xceed 250 mm. 250mm
Pre-installation Check Check the telecommunications room,
cabinet, pow wer supply, ground wires, optical cables, and
associated facilities prior to installation. Start the installation
according to the engineering design documents after verifying that
conditions are met.

Instructions and Precautions for Handling g Boards
Do not hold a board without hand protection. Wear an ESD wrist
strip or ESD gloves before handling a board. Wearing ESD gloves
Wearing an ESD strip Holding a board without hand protection
Hold the front panel of a board with hands.
Insert filler panels into vacant slots on an NE to pr revent
foreign matters from getting into the NE, which may result in
faults on the NE. Boards are fragile and valuable. When handling or
o placing a board, exercise caution and put it into a dedicated
packing box.

Installation Requirements of the Cabinet an nd Mounting Ears
Before installing the equipment, ensure that the cabinet has
already been installed. The cabinet can be installed on the ESD
floor or concrete floor. For details about how to install the
cabinet, see the Cabinet Installation Guide delivered with the
cabinet. The equipment can be installed in an ETSI cabinet, a
21-inch open rack, or a 19-inch standard cabinet. ETSI2119
The equipment can be installed when no guide rail is s provided.
You can install the mounting ears and equipment based on the
following procedure: 1. Separately mount M6 screws into the
bottom-lowe er floating nuts of the mounting bar on both sides of
the cabinet, and reserve sufficient space for installing mounting m
ears between the screws and the mounting bar. Then, confirm that an
appropriate length of M6 screw ws is inserted into the floating
nuts to avoid fall-off of the chassis. 1 1. M6
2. Place the chassis into the cabinet. Note: Place the t
cucurbit-shape holes in the lower part of the mounting g ears onto
the M6 screws and use the M6 6 screws to secure the chassis onto
the cabinet. 2. M6M6
9
The default mounting ears are applicable to the situa ation
where the equipment is installed in a 19-inch standard cabinet.
When installing the equipment in another ty ype of cabinet, use
other mounting ears as required. When installing the equipment in a
21-inch cabinet, install two t sets of mounting ears. That is,
retain the default mounting ears ears, and install another set of
mounting e ears for the equipment installed in the 21 21-inch inch
cabinet cabinet. 19 21 21 Generally, install mounting ears in an
ETSI cabinet. ETSI Install mounting ears in a19-inch standard
cabinet. 19
Install mounting ears in an N63B cabinet. N63B
Cabinet-sharing Installation The RTN 980 can be placed in a
stacked manner. When the RTN 980 and other type of equipment are e
installed in the same cabinet, it is recommended that you reserve a
2U or greater space for heat dissipatio on. 2U When the RTN 980 and
other type of equipment are e installed in the same cabinet, the
temperature in the air outlet needs to be lower than 50C if the
lower equipment e emits the air on its top. Otherwise, use an air
guide plate for separation between the upper equ uipment and the
lower equipment. 50

Installing Fibers Precautions
When installing or maintaining fibers, do not look into o the
optical port without eye protection. See Figure 1. Coil up the
inter-office fibers on the ODF and then ro oute them into the
cabinet. Do not coil up external fibers in the cabinet. 1 ODF
When routing fibers, take proper measures to avoid any damage to
fiber connectors After installation of the fibers, place protective
caps on o to the idle optical ports, and place fiber caps on to the
idle fibers. See Figure 2. 2 Figure 1 1 Figure 2 2Fiber with a
short protective tube Fiber cap
Pluggable optical module
p cap p Dustproof
For a closed corrugated pipe, take protective measur res and
then route fibers into the corrugated pipe. For an open corrugated
pipe, route fibers into the corrugated d pipe and then take
protective measures. After routing fibers into a corrugated pipe,
wrap PVC insulation tapes around the cuts of the corrugated pipe.
Do not feed a large number of fibers in a corrugated pipe. p It is
recommended that you feed not more than sixty 2 mm di diameter t
fib fibers i in an open corrugated t d pipe i and d not t more th
than t twenty t 2 mm di diameter t fib fibers in i a closed l d
corrugated pipe (See Figure 3). The corrugated pipe needs to be
routed into the cabin net for approximately 10 cm (See Figure 4).

Aligning Dual-Polarized Antennas
If an OMT is used to connect the ODUs to the anten nna in
direct-mounting mode, align the antenna in the same method as that
for aligning single-polarized antenna as. If soft waveguides are
used to connect the ODUs to the antenna in separate-mounting mode,
follow the proc cedure to align the antenna: ODUOMT ODU Power off
the vertically polarized ODUs at both ends of a radio link, power
on the horizontally polarized ODUs at both ends of the radio link.
This p ensures that the antennas at both ends transmit horizontally

What Wh t to t Check Ch k For F The chassis must be installed
securely in the position as specified s in the engineering design
documents. Each chassis component does not have any paint drop,
damage, d or stain. Otherwise, re-paint or clean the component. For
a board inserted into the chassis, the screws on the fr ront panel
are tightened. Filler panels are installed for vacant slots in the
chassis. Cable routes comply with the engineering design docume
ents and facilitate maintenance and expansion. Cables are not
damaged, broken, or jointed in between. E h core of Each f th the
cables bl i is t tested t df for connectivity. ti it Cables are
properly bound. Cable ties are installed at equ ual spacing and in
the same direction. The excess of cable ties is trimmed off without
remaining rough edges. Signal cables are routed correctly in the
cabinet. Cables outside the cabinet are routed as follows: The
cables are placed tidily and are not cross-connected d. If a
cabling ladder is used, the cables are bound onto the ladder beam
tidily. If the cabling frame is 0.8 m or more higher than the
cabinet top, a cabling ladder is available on the cabinet c top to
support the cables and to ease stress. 0.8m Cable turns are smooth
and have a great bending radius. . Cable labels are filled in
correctly and attached securely. They are aligned and face to the a
from the connectors. same direction. Preferably, the labels are
attached 2 cm away 2cm The power cable and ground cable are routed
separately from the signal cables. Idle cable connectors are
protected. For example, protect tive caps are installed on the idle
connectors. Protective tube for fiber jumpers are routed into the
cabinet for 10 cm and bound securely. 10cm The cuts of protective
tubes for fiber jumpers are smooth. . Otherwise, they need to be
wrapped by an insulation tape. Fiber jumpers are bound gently to
ensure free move in the e cable tie. Connecting gp points of fiber
