ZXSDR BS8900A Integrated Outdoor LTE Macro eNodeB Product Description
ZXSDR BS8900A Integrated Outdoor LTE Macro eNodeB Hardware Description
2.2 Precautions for cabinet transport
A cabinet must be transported with the outer packing container to protect the cabinet
from scratches.
Caution!
You must transport a cabinet in a packing container.
After the packing container is removed on site, the cabinet must be protected when
you move or store it. For example, when a cabinet is stored temporarily, cushioning
materials must be put under the bottom of the cabinet to avoid direct contact with the
ground and surrounding objects.
When you transport a cabinet, use machines first. When you lift a cabinet up, the
cabinet must be dragged properly to avoid collision with other objects.
If a cabinet has to be transported without packing due to environment restrictions,
cushioning materials such as foamed plastic and paperboard must be used to protect
the cabinet from scratches.
2.3 Installation Precautions
The following precautions should be abided by during the installation:
The ZXSDR BS8900A hardware installation personnel must participate in the training
related to communication equipment installation to master installation skills.
During the installation, ensure the personal safety and avoid accidents such as electric
shock or bruise.
The installation personnel should wear an antistatic wrist strap when inserting and
pulling out boards. Ensure that the other end of the antistatic wrist strap is grounded
well.
When taking a board, take hold of the edge of the board and do not touch the circuit,
components, and wires.
Install boards along slots and avoid contacting adjacent boards to avoid short circuit.
Give proper force to install the boards to avoid pin distortion.
When installing or maintaining an optical fiber, do not directly stare at the section of
optical fiber or an optical socket in case that laser beams hurt your eyes.

Chapter 4
Cabinet Installation
The ZXSDR BS8900A is an outdoor device that is directly floor-mounted. It can be installed
at a hill or roof. In general, a simple fence or house is required around the base station
where the equipment is installed in the hill or under a tower.
A concrete platform needs to be set up before the cabinet installation to protect the base
station equipment and ensure the normal usage of the communications equipment.
The ZXSDR BS8900A has three types of cabinets, the baseband cabinet (BC cabinet), RF
cabinet (RC cabinet), and battery cabinet (PC cabinet). These cabinets can be stacked or
installed side by side. The lower-layer cabinet in the stacked cabinet installation mode is
RC8910A or PC8910A. The upper-layer cabinet in the stacked cabinet installation mode is
BC8910A. The base does not accompany the delivery of these cabinets. The base needs
to be installed before the floor-mounted cabinet installation.

4.2 Floor Mounting the Cabinet
This procedure describes how to mount a cabinet or the lower cabinet of the stacked
cabinets on the floor.
You can install the ZXSDR BS8900A cabinets in multiple modes as required, for example,
stacking the BC8910A cabinet and RC8910A cabinet together with the PC8910A cabinet,
and installing single BC8910A cabinet. The installation of the BC8910A cabinet or
PC8910A cabinet on the floor is slightly different from that of a RC8910A cabinet. No
clamping component is required for the installation of the BC8910A cabinet or PC8910A
cabinet.

Cable Routing Requirements
Before power cables and grounding cables are laid out, the connectors must be
covered by insulation tape.
The power cables, grounding cables, and signal cables must be routed separately.
When signal cables, DC power cables, AC power cables, and feeders are routed in
parallel along a cable ladder, ensure that a spacing greater than 100 mm is reserved
between different types of cables.
If signal cables and power cables need to be laid out in a cross manner, the cross
angle must be 90°.
If a cable needs to bend, ensure that the bending radius meets the minimum bending
radius requirement, meaning that the bending radius must be equal to or greater than
20 times of the cable's outer diameter.

ZTE Proprietary and Confidential
ZXSDR BS8900A Hardware Installation
When the power cable is connected to the connector of the power distribution box in
the cabinet, the cable must be routed in a smooth and straight manner.
The actual installation positions of the cables must meet the engineering survey
requirements and be consistent with configurations.
The cable routing paths are clear and reasonable with even and smooth bends, and
meet the specifications in engineering drawings.
Signal cables are aligned neatly and smoothly without cross.
Cables are laid out for convenient maintenance and capacity expansion.
You know clearly the planned route of each feeder. It' etter to draw the routing in a
piece of paper to avoid reword due to feeder cross.
The bending radius of a common feeder must be greater than 20 times of the outer
diameter. The bending radius of a soft feeder must be greater than 10 times of the
outer diameter.
For the requirements of the bending radius of feeders, refer to Table 7-1.

7.4.2 Installing a Grounding Cable for the RC8910A Cabinet and
PC8910A Cabinet
For stacked cabinets, the grounding cable of the lower cabinet is connected to the
grounding busbar of the BC8910A cabinet.
The grounding cable of the single cabinet is connected to the outdoor grounding busbar.
For stacked cabinets (BC8910A cabinet and RC8910A cabinet), the RC8910A cabinet
is grounded through the grounding busbar of the BC8910A cabinet. For a standalone
PC8910A cabinet, the PC8910A cabinet is grounded directly.
Prerequisite
The ESD wrist strap must be worn.
The tributary output of the power supply is cut off.
Steps
Installing the grounding cable of stacked cabinets
1. Prepare the grounding cable of a particular length in accordance with the distance
between the BC8910A cabinet and the grounding copper bar.
Note:
A redundant length must be reserved when you prepare the grounding cable.
2. Remove the screw configured for the ground nut on the side of the RC8910A cabinet
and secure one end of the grounding cable to the grounding point at the top-left corner
of the cabinet.
3. Route the grounding cable along the left-side cable-through hole and the left-side
ground copper bar of the BC8910A cabinet, see Figure 7-13.

7.5 Power Cable Installation
The power cables include AC or DC input cables of the BC cabinet, DC input cables of the
RC cabinets and PC cabinet.
The power cable connections of the three cabinets of the ZXSDR BS8900A depend on the
power supply mode (AC or DC) of the BC cabinet.
AC Power Input for the BC Cabinet
AC power is supplied to the B201, B900, or B121 PDM of the BC8910A cabinet, converted
to be DC power in the PDM, and then distributed to other cabinets. For the AC power
distribution of the ZXSDR BS8900A cabinets, see Figure 7-14.
Figure 7-14 shows the power distribution from the BC8910A cabinet to the RC8910A and
PC8910A cabinets when the B121 PDM is installed. When installing the ZXSDR BS8900A
cabinets, you need to connect the corresponding power cables in Figure 7-14 as required.
The way to connect the cable of the B201 PDM is similar to that of the B121 PDM.

If the ZXSDR BS8900A connects RRUs, the DCPD6 module is installed in the baseband
cabinet to provide power for RRUs. For power cable connections, see Figure 7-15. The
BBU subrack is powered by the DCPD module. Figure 7-15 shows the power distribution
when the B201 PDM is installed. The way to connect the cable of the B121 PDM is similar
to that of the B201 PDM.
