Chapter 1 Overview
Installation Precautions
The installation personnel of the RA25 must check the running
environment of the equipment and learn about the
communication networking and data configuration of the
operator, the status of the equipment in the network, the
interfaces of the line transmission equipment, and the lengths of
various cables prior to installation, for successful commissioning
of the project. The hardware installation personnel must read
carefully the installation manual before the installation.
In addition, pay attention to the following:
n Do not operate with the chassis or any module when it is
energized during the installation.
n Do not install the antenna feeder system in the case of
lightning.
n Verify the various lightning arresters (including the power
supply lightning arrester, RF lighting arrester, and main
antenna feeder arrester) are in good contact and good
condition. Replace any damaged ones.
n Lock the door in time after the chassis has been installed. If
any maintenance needs the door being opened, all
operations must be performed under the guidance of
professionals.

Chapter 2 Installation Preparations
Unpacking Inspection
The ZTE Engineers must perform the unpacking inspection along
with operator’s side engineers.
1. Check whether the total pieces are correct, packages are in
good condition, and the destination location matches the
installation location. If the results are all normal, start
unpacking inspection.
2. The equipment inspection list and unpacking inspection
report are contained in package #1. First open the #1
package and take out the Unpacking Inspection Report.
Check the total number of the goods against the inspection
list and record it for filing.
3. If any item is missing, lack, incorrect, excessive or damaged,
the reason must be found out, and the engineering
supervisor should fill in the Unpacking Inspection Feedback
Table, which must be fed back to ZTE in time for handling.
Note: When the equipment is moved a hotter and damper place,
wait for 30 minutes before unpacking the equipment. Otherwise,
moisture may condense on the surface of the equipment and damage
the equipment as a result.
Wooden Case Unpacking Procedure
1. Insert the screwdriver or claw hammer into the tab hole on
the cover plate of the wooden case, and turn the tab straight;
2. Lift and remove the cover plate after all tabs have been
turned straight;
3. Turn straight the tabs of the plates on four sides of the
wooden boxes, and remove the plates.
Confidential and Proprietary Information of ZTE CORPORATION 13
ZXMBW RA25 Agile 2.5G Remote Radio Frequency Unit Installation Manual
Carton Unpacking Procedure
1. Cut the straps by using the diagonal pliers;
2. Cut the adhesive tape along the slits on the cover by using a
paper cutter. Note that the cut shall not be too deep to avoid
damaging the goods inside;
3. Open the carton and take out the foam pads;
4. Check the contents in the carton against the attached
delivery list.
Note: Do not damage the antistatic bags during the unpacking
inspection process, as they may be useful in future storage of spare
parts and return of failed parts.
Properly dispose of the desiccants to keep them away from children.
Goods Acceptance and Handover
1. Acceptance check
Check the goods carefully one by one for acceptance
according to the names, models, and quantities shown on
the packaging list:
n There must not be dents, bulges, scratches, peels, blithers,
blisters or stains on the outer surface of the chassis.
n The surface paint on the cabinet must not peel off or be
scratched.
n The fastening bolts must be tight, not fall off or be displaced;
n The accessories and fittings needed for installation shall be
complete.
n Arrange the inspected goods in good order by category.
2. Handover
After inspection, the user representative and the engineering
supervisor must sign on the Unpacking Inspection Report . In
accordance with the contract, if the goods are to be kept by
the equipment operator after inspection, the goods should be
handed over to the equipment operator after both parties
sign on the Unpacking Inspection Report.
