Unqualified drilling could damage wiring and cables inside the chassis.
Additionally, metal pieces inside the chassis created by the drilling could result
in a short circuit. Use insulation protection gloves and first move cables inside a
chassis away when drilling is necessary on a chassis.
à
Protect eyes during drilling as dust or flying debris may damage eyes.
à
Clean any debris in time after drilling.
Lightning
Danger!
Do not perform high-voltage, AC, iron tower or mast operations in a thunderstorm.
Thunderstorms would give rise to a strong electromagnetic field in the atmosphere.
Therefore, the equipment must be grounded and protected in time against lightning
strikes.
Antistatic Safety Instructions
Caution!
Static electricity produced by human body can damage static-sensitive components on
circuit board, such as large-scale integrated circuits.
Friction caused by human body activities is the root cause of electrostatic charge
accumulation. Static voltage carried by a human body in a dry environment can be
up to 30 kV, and can remain there for a long time. An operator with static electricity
may discharge electricity through a component when he/she touches the conductor
and causing damage.
Wear an antistatic wrist strap (the other end of wrist strap must be well grounded)
before touching the equipment or holding a plug-in board, circuit board, Integrated
Circuit (IC) chip or other devices, to prevent human static electricity from damaging
sensitive components.
The antistatic wrist strap used must be subject to regular check. Do not replace the
cable of an antistatic wrist strap with any other cables.

SJ-20110823164828-001|2011–08–16
ZTE Proprietary and Confidential
Chapter 4 RSU60E
Do not contact static-sensitive modules with any object that easily generates static
electricity. For example, friction of package bag, transfer box and transfer belt made
from insulation plastic may cause static electricity on components. Discharge of static
electricity may damage components when they contact a human body or the ground.
Modules should only contact materials such as an antistatic bag. Keep modules in
antistatic bags during storage and transportation.
Discharge static electricity of the test device before use, that is, ground the test device
first.
Do not place the module near a strong DC magnetic field, such as the cathode-ray
tube of a monitor. Keep the module at least 10 cm away.
Hoisting Heavy Objects
Warning!
When hoisting heavy objects, ensure that nobody is standing or walking under the hoisted
object.
Ensure the hoister can meet hoisting requirements when disassembling heavy
equipment, or moving and replacing equipment.
The installation personnel must be duly trained and qualified for hoisting operations.
Hoisting tools must be inspected and complete before service.
Make sure that hoisting tools are fixed firmly on a sufficiently secured object or wall
before the hoisting operation.
Give brief oral instructions during hoisting operations to prevent any mishap.
Unplugging/Plugging a Module
Never plug a module with excessive force, to ensure that the pins on the backplane
do not get deformed.
Plug the module right into the slot and make sure module circuit faces do not contact
each other lest any short circuit may occur.
Keep hands off the module circuit, components, connectors and cable trough when
holding a module.
Rack Mount Safety Instructions
Rack Mount Instructions - The following or similar rack-mount instructions are included
with the installation instructions:
Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by
the manufacturer.

amount of air flow required for safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g. use of power strips).
Other Safety Instructions
Note:
Do not perform maintenance or debugging independently, unless a qualified person is
present.
Perform an airtight test before RRU delivery, and prohibit disassembling the RRU on
site.
Replacing any parts or making any changes to the equipment might result in an
unexpected danger. Therefore, be sure not to replace any parts or perform any
changes to the equipment unless authorized otherwise.

in delivery. After the RSU module is installed, insert the terminal of the RSU monitoring
cable to the MON (monitoring) interface of the RSU module.
Note:
If multiple RSU modules need to be monitored, only one RSU module needs to be
connected to the RSU monitoring cable.
Steps
1. Connect one end of the RSU monitoring cable to the MON (monitoring) interface of
the RSU module and fasten the screw.
2. Bundle the RSU monitoring cable.

4.5.3 Installing Optical Fibers Between BBU and RSU
Prerequisites
The ESD wrist strap must be worn.
The baseband power cabinet and the RF cabinet have been independently installed.
Context
When the baseband power cabinet and the RF cabinet are installed side by side or they
are far away from each other, you need to connect BBU and RSU using optical fibers.
Pay attention to the following points when installing optical fibers:
Do not damage the optical fiber cladding during operations.
Protect optical fiber connectors and avoid contaminating them.
Do not forcibly bundle optical fibers.
Curve optical fibers at the turning.
Steps
1. Affix a temporary label.
Affix temporary labels to both ends of the new optical fiber to set up a mapping. If
more than one optical fiber needs to be installed, use different labels to differentiate
optical fibers.
2. Route optical fibers.
a. Optical fibers go out from the side waterproof module of the baseband module and
go through the routing apertures on the base.
b. Then, optical fibers go through the routing apertures on the base of the RF cabinet,
traverse the waterproof modules, and connect to the six optical interfaces for RF
modules.
3. Insert optical fiber connectors.
Insert optical fiber connectors according to the mapping on temporary labels.
Caution!
Insert optical fiber connectors tightly.
4. Bundle optical fibers.
Bundle and secure optical fibers along the routing troughs, which complies with
relevant regulations.
5. Affix an engineering label to an optical fiber.
Remove the temporary label for the optical fiber and affix an engineering label.

2. Insert one end of the SFP cable to a TX/RX interface of RSU.
3. Route the SFP cable along the routing trough and cabinet sides to the FS module of
BBU. The SFP cables connecting to the RSUs in slots 1 to 3 on the RF cabinet go
through the left routing apertures and those SFP cables go through the right apertures
if connecting to slots 4 to 6 on the RF cabinet.
4. Insert SFP cables into the interfaces TX0RX0 to TX5RX5 of the BBU FS board
according to the markings 0-5.
5. Bundle SFP cables.
6. Remove temporary labels and affix engineering labels.

right.
Remove the front baffle of the base before installing the RF jumpers and reseat the front
baffle after all jumpers are completely installed.
Steps
1. Connect the RF jumpers to ANT1 and ANT2 interfaces of RSU from left to right.
2. Wear the waterproof rubber plug after every two RF jumpers are installed.
3. Insert the horizontal and longitudinal slide blocks and use the hexagon ring wrench to
fasten them.
