Site Requirements
3
To ensure personal and equipment safety, observe all the safety
precautions on the equipmentand in this document.
and and items do not cover all the safety precautions and
are only supplementary to the safety precautions. The device needs to be installed in a clean, dry, well ventilated, and
temperature-controllable standard equipment room. In addition, the
equipment room must be free from leaking or dripping water, heavy
dew, and condensing.
Dustproof measures must be taken in the installation site. This is
because dust will cause electrostatic discharges on the device and
aect connections of metal connectors and joints, shortening the
service life of the device and even resulting in device failures.
The installation site must be free from acidic, alkaline, and other
types of corrosive gases.
The device that is operating may cause radio interference. If this is the
case, relevant measures may be needed to reduce the interference.
Generally, devices such as wireless antennas should not be installed in
the equipment room. If such devices must be installed indoors, ensure
that the electromagnetic environment meets relevant requirements or
take necessary electromagnetic shielding measures.
The device to be installed must be used indoors. To ensure normal
operation and long service life of the device, the following requirements
must be met:
The temperature and humidity in the installation site must meet device
requirements described in the following table.

Cabinet Requirements
4
Installing a Device
5
The device must be installed in an IEC 19-inch cabinet or an ETSI 21-inch
cabinet.
Huawei A63B cabinet is recommended. If customers choose to purchase
cabinets by themselves, the cabinets must meet the following require-
ments:
NOTE
1. 19-inch or 21-inch cabinet with a depth of greater than or equal to
300 mm.
2. The cabling space in front of the cabinet complies with the cabling
space requirements of boards. It is recommended that the distance
between the cabinet door and any device board be greater than or equal
to 120 mm. If the cabling space is insucient, cables will block the
cabinet door from closing. Therefore, a cabinet with broader cabling
space is recommended, such as a cabinet with a convex door.
3. The device draws air from the left side and exhausts from the right
side. Therefore, if the device is installed in a 19-inch cabinet, there must
be a clearance of at least 75 mm at the left and right sides of the cabinet
to ensure good ventilation.
4. The porosity of each cabinet door must be greater than 50%, meeting
heat dissipation requirements of devices.
5. The cabinet has installation accessories, such as guide rails, floating
nuts, and screws.
6. The cabinet has a ground terminal to connect to the device.
7. The cabinet has a cable outlet on the top or at the bottom for
overhead or underfloor cabling.
The cabinet may be installed on an ESD floor or a concrete floor. For de-
tails about how to install a cabinet, see the Cabinet Installation Guide
delivered with a cabinet.
When installing a device in a cabinet, ensure that the total heat
consumption of all devices in the cabinet does not exceed the heat
dissipation capability of the cabinet.
To prevent air return from aecting heat dissipation, leave at least 2 U
space between devices in the cabinet. In addition, if the cabinet has
middle columns, devices can be installed in stacking mode.
Do not block the heat dissipation holes on panels.
A device that needs to share the same cabinet with other devices cannot
be installed near the air exhaust vents of those devices.
Consider the impact of a device's air exhaust vent on adjacent devices to
prevent high temperature.
When fastening floating nuts, ensure that there is at least 75 mm space
on the left and right sides of the device for ventilation after device
installation.

Routing Planning
It is recommended that cables, including E1 cables, optical fibers, and
Ethernet cables, be routed on the left side of the cabinet.
If cables are routed on the rear of a device, ensure that the cables do not
block the air vents of the device to achieve proper heat dissipation.
Before routing cables, make temporary labels and attach them to the
cables. After the cables are routed, make formal labels and attach them
to the cables as required.
Do not bundle or route outdoor cables (such as outdoor antenna feeders
and outdoor power cables) and indoor cables together in the cabinet or
cable tray.
NOTE
CAUTION
It is recommended that the power
cables of a DC device be routed on
the right side of the cabinet. To
facilitate fan module maintenance,
keep the cables away from the upper
or lower fan module insertion and
removal areas.

reconnect it.
Check whether the cables have
been properly connected and
whether the cable sheath has
been pressed through view
windows. If not, repeat the
preceding steps to prepare and
connect the cables again.
The conductor of each power cable must be completely inserted into
the DC connector to prevent electric shocks. Shut down the power
supply before connecting or disconnecting power cables.
The power cables must be correctly connected according to the
labels on the PIU. If the power cables are reversely connected, the
device cannot be powered on.
Ensure that the power cables do not have joints or excess part, and
are not coiled. The bent part of the cables must have enough slack,
with a bending radius of no less than 20 mm.
No bare copper wire is allowed at power cable terminals.

Installing an E1 Cable
To avoid aecting right-hand board maintenance after cable routing, you
are advised to connect an E1 cable only to a left-hand board.
An E1 cable is a thin cable with a diameter of 1.6 mm. It needs to be con-
nected to a DDF using an MC 75-1-1 connector and a crimping tool with
a bore diameter of 1.7 mm. If you use an MC 75-1-1 connector and a
crimping tool with a bore diameter of 2.5 mm, crimp the joint twice. Spe-
cifically, after performing the first crimping, rotate the coaxial connector
by 90 degrees and crimp the joint again.
An E1 cable with a negative 45-degree connector is delivered by default.
If you use this cable, connect the connector to the desired board port and
use a Phillips screwdriver to fasten screws.
If you use an E1 cable with a positive 45-degree connector, the cable must
be routed without aecting fan module installation or removal. To
achieve this, you need to use an E1 transfer cable instead of directly con-
necting the connector to a board port. Specifically, connect the cable to
the E1 transfer cable, and then connect the E1 transfer cable to the de-
sired board port.
NOTE

outlet without eye protection.
WARNING
CAUTION
Before routing internal optical fibers, install fixed optical attenua-
tors at the corresponding optical ports on boards according to the
fixed optical attenuator installation table.
If you use the recommended A63B cabinet, it is recommended that
only one optical attenuator be added. If multiple optical attenua-
tors are added, there is a risk that the cabinet door cannot be prop-
erly opened.

Handling Corrugated Pipes
Installing Optical Fibers
The bending radius of a single-mode G.657A2 optical fiber is no less
than 10 mm, and that of a multi-mode A1b optical fiber is no less than
30 mm.
After laying out optical fibers, use binding straps to bind the fibers
neatly without squeezing them.
After the optical fibers are connected, the optical ports and optical con-
nectors that are not used must be covered by dustproof plugs and dust-
proof caps, respectively.
Do not use an open-end corrugated pipe to hold excessive optical fibers.
It is recommended that an open-end corrugated pipe with a diameter of
32 mm accommodate a maximum of 60 fibers with a diameter of 2
mm.
It is recommended that the length of a corrugated pipe inside a cabinet
be about 10 cm.
Use an A63B cabinet as an example. If corrugated pipes need to be used
in the cabling area on the top of the cabinet, a maximum of two such
pipes are supported, accommodating a maximum of 120 optical fibers.
If more optical fibers are required, use the E1 cable hole.

Installing Ethernet Cables
Installing a 75-ohm Coaxial Cable
The maximum number of shielded Ethernet cables supported by a flat-door
cabinet is limited. For example, a 300 mm deep flat-door N63B/N63E cabi-
net supports a maximum of six shielded Ethernet cables per layer of inter-
face boards.
In contrast, a convex-door cabinet supports more shielded Ethernet cables.
For example, a convex-door A63B/A63E cabinet supports a maximum of 16
shielded Ethernet cables per layer of interface boards.
Connecting a device to an NMS server requires two Ethernet cables: one for
the active main control board and the other for the standby main control
board.
