Installation Checklist
 Cabinet installation checklist
No. Item
1
The installation position of the cabinet strictly complies with the
engineering design.
2 The base is securely installed.
3
All the bolts, including those for electrical connections, are
tightened. The spring washers and the flat washers are installed
in the correct sequence.
4 The cabinet is neat and clean.
5 The paint on the surface is intact. The damaged paint is repaired.
6
Labels, tags, and nameplates are correct, legible, and complete.

 Installation environment checklist
No. Item
1
No excessive straps or adhesive tapes are left on the cables.
2
No tapes, tails of cable ties, paper, or packing bags are left
around the cabinet.
3
Antirust powder on the door of the cabinet is cleared.

 Electrical connection checklist
No. Item
1
All self-made PGND cables are copper-based with proper core
diameters. There should not be any switch or fuse in the
grounding system. No short circuit is allowed
2
The PGND cable is securely connected and the AC input power
cable and cables in the cabinet are correctly connected
according to the electrical design of the power system. The
screws are tightened. In addition, the inputs or outputs are not
short circuited.
3
The redundant part of the power cable or PGND cable is cut off
rather than coiled
4
The terminals at both ends of the power cable or PGND cable
are securely soldered
or crimped.

No. Item
5
The bare wires and the terminal handles at the wiring terminals
are coated with heat shrink tubing.
6
The flat washers and the spring washers are well mounted on all
OT terminals
7
The exterior of the storage battery is intact without any scratch,
dent, or crack.
8
The shell of the storage battery is clean without any leakage
trace
9
The wiring terminal on the storage battery stands properly
without any damage, and
the post is not covered with any acid substances.
10
The pressure relief valve of the battery is not deformed, and no
liquid leaks

No. Item
11
The power cables for the storage batteries are correctly
connected to the positive and negative poles.
12
The voltage of the storage battery is normal.
The voltage of a 2 V storage battery ranges from 1.8 V to 2.35 V.
The voltage of a 12 V storage battery ranges from 10.8 V to 14.1 V.
The total voltage of the storage batteries ranges from 43.2 V to 56.4 V.
13
The circuit breakers for the storage batteries are set to OFF.

 Cable Installation Checklist
No. Item
1
All cables, especially the Ethernet cables for communication, are
securely connected. All cable connectors at the bottom of the
cabinet are securely installed
2
The cables are neatly and tightly bound. The cable ties are
evenly spaced and face the same direction.
3
Different types of cables, such as the power cable, PGND cable,
feeder, fiber optic cable, E1/T1, and FE/GE signal cable are
separately bound.
4
The layout of all cables facilitates the maintenance and capacity
expansion. For example, the maintenance transfer cable is
bound to the outside of the BBU cable claw, as shown in the
following figure.

 Cabinet installation checklist
No. Item
5
All the labels at both ends of the cables are legible.
6
The extra length of the indoor cable ties is cut off, and the cut
surfaces are smooth without sharp edges. The extra length of 3
mm (0.11 in.) to 5 mm (0.19 in.) of the outdoor cable ties is
reserved when the cable ties are cut.
7 The port that no cable is connected to is properly protected.
8
The connectors of the RF cables are secured to avoid false
connection that will cause an abnormal voltage standing wave
ratio (VSWR).

Powering On a Base Station
NOTE:
 The cabinets must be powered on in seven
days after being unpacking, and the period
of the power-off state of the cabinet cannot
exceed 48 hours during the maintenance
 Ensure that the external power supply is
normal before power on, and that all the
circuit breakers in the cabinet are set to
OFF
 If an indicator that indicates the status of a
CPRI port on a BBU board is steady red,
check whether the optical module is faulty
or the fiber optic cable is broken

General Cabling Requirements

Use the cable tie with white color indoor and black color outdoor.

The distant between two cable tie is between 20cm to 40cm (less
than 25cm in perpendicular direction), and the tie should be in
the same direction.

Cables of the same type must be bound together.

Different types of cables must be separately laid out and bound,
with a minimum distance of 30 mm (1.18 in.) from each other.

The cables must be bound tightly and neatly. The sheaths of the
cables must not be damaged.

The excess of the indoor cable ties is cut off. The excess of 5 mm
(0.197 in.) of the outdoor cable ties is reserved, and the cut
surfaces are smooth without sharp edges.

Outdoor Cabling Requirements

Protect outdoor cables against potential damage. For example, put the cables through tubes.

The cables to be protected include AC power cables, transmission cables, and cables laid out
underground.

Determine the positions where the clips are installed according to the actual situation. For example,
7/8" feeders are secured with clips at an interval of 1.5m to 2m, CPRI fiber optic cables and power
cables are secured with clips at an interval of 1m to 1.5m. Ensure that the clips are evenly spaced and
in the same direction.

NOTE:

There are two types of clips: 3-hole clip and 6-hole clip, which are described as follows:
(1) Cable hole for feeders (2) Cable hole for fiber optic cables (3) Cable hole for power cables
