1.1 Distributed eNodeB Solution
To supply customers with more competitive communication equipment and solution in the
market, ZTE develops and promotes ZTE SDR eBBU (baseband unit) and eRRU (remote
radio unit) distributed eNodeB solution timely, which jointly perform LTE eNodeB service.
ZTE distributed eNodeB solution is shown in Figure 1-1.

Figure 1-1 ZTE Distributed eNodeB Solution
ZTE's LTE eBBU+eRRU distributed eNodeB solution has the following predominance:
1. Saving labor cost and engineering cost for networking.
eBBU+eRRU distributed eNodeB equipment is small in size, light in weight, and easy
for transportation and engineering construction.
2. Fast networking, also saving the fees of renting equipment room.
eBBU+eRRU distributed eNodeB is applicable to various sites, such as mounted on
steel tower, on building top, or on wall, etc. It's more flexible in selecting installation
site, and not
restricted by the space of equipment room. It can help operators to deploy
network rapidly. It can also save the fees of renting equipment room, and the network
operation cost.
3. Convenient in upgrade and capacity expansion; saving the initial stage cost of the
network.
eRRU can be mounted as close to antenna as possible, to save the cost of feed cable
and decrease the loss of feed cable. It also can enhance the output power of eRRU
and increase the coverage.
4. Low power consumption, power-saving.

Chapter 1 Product
Overview
Compared with traditional eNodeB, eBBU+eRRU distributed eNodeB has lower power
consumption, which can greatly reduce the investment and cost on electric power, and
thus save the network operation cost.
5. Distributed networking, making good use of operators' network resources supporting
eBBU+eRRU distributed networking; supporting star networking mode between eBBU
and eRRU.
6. Adopting a more perspective and generalized eNodeB platform.
eBBU adopts the platform designed for the future B3G and 4G. One hardware platform
can realize different standard modes, and several standard modes can coexist in one
eNodeB. In this way, operators' management can be simplified, and several eNodeBs
to be invested can be integrated into one eNodeB (multimode eNodeB). The operators
can select the evolution direction of the future network more flexibly.
1.2 Product Position in Network
ZXSDR R8882 L708 is a remote radio unit (eRRU) of distributed eNodeB. The signal is
transmitted or received through ZXSDR R8882 L708 to and from base band processing
unit for further processing through CPRI interface. By applying the distributed system, the
feeder loss will be reduced when the remote radio unit is positioned close to the antenna.
The coverage is enlarged with this solution.

2.1.3 Safety Operation Guidance
Electrical Safety
1. Tool
When operating in the case of high voltage, use special tools. Do not use general
tools.
2. Power Cable
zCut off the power before installing or removing the power cable.
zBefore connecting the power cable, make sure the cable connection and labels
on the cable comply with the actual installation situation.
Danger!
zDo not install or remove the power cable when the power is ON.
zSparks or electric arc may happen when the power cable touches the conductor,
which may cause fire or eye injury.
3. Drilling
zUnqualified drilling will damage the lines and cables in the cabinet. The metal
splashes may enter the cabinet and cause the short circuit on the circuit board.
zWhen drilling on the cabinets is needed, wear insulating gloves and remove the
cables inside the cabinet before the operation. Take care of your eyes when
drilling, because metal splashes may hurt your eyes. Clean up the metal filings
once the drilling is done.
Warning!
Do not drill on the cabinet at will.
4. Thunderstorm
During thunderstorm, strong electromagnetic field will be produced in the atmosphere.
Thus, to avoid lightning strike, take lightning grounding measures on the equipment
immediately.
Danger!
During thunderstorm, do not perform operations of high voltage, and do not perform
operations on the iron tower or mast.

Antistatic
zThe friction caused by human activities is the reason to produce the accumulation of
electrostatic charge. In dry climates, electrostatic voltage carried by the human body
can be accumulated up to 30 kV, which will be kept in the body for couple of hours.
Operators carrying
electrostatic charge will be discharged through the device, causing
equipment damage.
zTo avoid damaging sensitive components by human static electricity, before touching
the devices, such as boards, circuit boards, IC chips, operators should wear antistatic
wristband, and make sure the other end of wristband touches the ground.
zTo protect people from accidental electric shock, a resistance over 1 MΩshould be
added between the antistatic wristband and the ground.
zThe antistatic wristband should be inspected periodically. Do not replace the electric
wires on the wristband by any other unqualified ones.
zThose electrostatic sensitive boards or modules should not have any contact with the
objects of electrostatic charge or which carries static electricity easily. For example,
friction between the packages of insulating materials and transmission belt could make
the
components carrying static electricity. Damages may happen when it is discharged
by contacting human body.
zThose electrostatic sensitive boards can be only contacted with qualified discharged
materials, such as antistatic bag. Equipment components need to be stored or
transported in the antistatic bags.
zBefore the testing equipment is wired with boards or modules, it should be connected
to ground for discharging.
zDo not place the boards or modules near strong DC magnetic field. For example,
those monitors with Cathode-ray tube, safety distance is over 10 cm.
Caution!
Electrostatic charge produced by human body will damage the electrostatic sensitive
components on the circuit board, such as Integrated Circuit (IC), etc.
Lifting Weights
zThe adequate facilities with lifting capacity must be used for assembling, moving or
replacing the heavy equipments.
zThe staff for lifting operations is required to have qualified training. Lifting tools must
have periodic inspection, and must be used when it is a complete tool kit. Ensure that
the lifting tool can be firmly fixed on the fixture or load-bearing wall before any lifting
operations. Use simplified commands to prevent misoperation.

Warning!
During lifting operations, do not walk at the bottom of any crane or lifting objects.
Plugging/UnpluggingBoards or Modules
zTo avoid crooking the pin on backplane, plug the boards or modules gently.
zPlug the boards or modules along the slot to prevent any short circuit.
zWhen carrying the boards or modules, do not touch the circuits, as well as the
components, connection heads, slots on the boards.
Others
zReplacing the components or modifying the equipments may cause extra dangers.
zDo not replace the components or modify the equipments without authorization.
zFrom safety point of view, please contact ZTE CORPORATION for any queries.
Caution!
Do not perform maintenance or debugging inside the device, unless there is another
qualified engineer working with you.
