Caution
Indicates a potentially hazardous situation which, if not avoided, could result in serious injuries, equipment damages or interruption of part services.
1.3 Safety Instructions
This section describes the safety instructions related to electrical safety, antistatic, heavy objects and modules.
Electrical Safety Instructions
The following are the electrical safety instructions about tools, high voltage, power cables, holes and lightning:
•Tools
Use special tools rather than common tools for high-voltage and AC operations.
•High Voltage
Danger
High voltage is hazardous. Direct or indirect contact with high voltage or main supply using a wet object could result in death.
àStrictly follow local safety rules to install AC power devices.
àInstallation staff must be qualified for performing high-voltage and AC operations.
àDo not wear any watch, hand chain, bracelet, ring or any other conductive objects during such operations.
àPrevent moisture from accumulating on the equipment during operations in a damp environment.
•Power Cable

ZXSDR RSUC User Manual
Warning
Never install or uninstall power cables while they are live. Otherwise, the power cable, when contacting a conductor, may result in sparks or electric arc causing a fire or even damage to eyes.
àMake sure of shutting off power supply before installing or disconnecting a power cable.
àBefore connecting the power cable, make sure that the connecting cable and its label are appropriate for the actual installation requirements.
•Drilling Holes
Warning
It is not allowed to drill chassis holes without permission.
àUnqualified 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.
àProtect eyes during drilling as dust or flying debris may damage eyes.
àClean 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
Electrostatic
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

Chapter 1 Safety Description
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.
•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.
•Reduced Air Flow - Installation of the equipment in a rack should be such that the 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.
•Due to that RRU is in high temperature during running, the RRU should be installed in some regions out of operators' reach or strictly restricted.
•Contact ZTE office if you have any question, to ensure your safety.

2.1 Overview
ZTE Software Defined Radio (SDR) uses an architecture of separating the baseband part from the Radio Frequency (RF) part. This architecture features high integration, low consumption, flexible configuration and convenient installation & maintenance. The new generation ZTE CDMA Base Station (BS) products based on the SDR is the first SDR-based CDMA BS in the industry. It is able to help the operators have qualitative leap. The form of this product can be distributed BBU + RRU or BBU + RSU. The product form of ZTE SDR can be distributed BBU + RRU or BBU + RSU, macro BS or micro BS.
ZXSDR RSUC is the RSU part of ZTE CDMA2000 distributed SDR Common BTS Platform Solution. It provides functions including RF modulation/demodulation, forward power amplification, reverse low noise amplification, RF performance measurement and carrier power control etc.
With a smaller size and lighter weight, the ZXSDR RSUC has significant advantages for saving space, relocations, installation flexibility, and power savings. It designed for both indoor and outdoor applications.
