Safety Information Abide by All Safety Requirements To ensure personal and equipment safety, abide by safety precautions described in the label on equipment or in the manual when you install, operate, or maintain the equipment. The "Safety Warning", "Caution", and "Note" in the manual are not the contents of safety requirements. They are provided as the supplement to the safety precautions. When operating Huawei products or equipment, strictly follow all precautions and special safety instructions required by Huawei. The "Safety Warning" in the manual is only based on the knowledge of Huawei. Huawei will not assume any responsibility for the loss incurred by operations violating the universal safety rules or standards for designing, producing, or using the equipment. Abide by the Local Laws and Regulations When operating the equipment, abide by the local laws and regulations. Requirements for Personnel The installation and maintenance personnel of Huawei equipment must be strictly trained. They are not allowed to install, operate, or maintain the equipment until they have mastered the correct operation method and got familiar with the safety requirements. Symbol Description If you ignore the warning, serious incidents such as casualties or equipment damage may be incurred. If you ignore the warning, incidents such as injuries or equipment damage may be incurred. This information is of help to operation.
Personal Safety Directly contacting or indirectly contacting high voltage power supply through wet objects is lethally dangerous. Incorrect high voltage operations will cause incidents such as fire or a shock hazard. Never perform any high voltage AC operations or perform operations on a tower or a mast during a thunderstorm. It can be lethally dangerous. Any equipment must be grounded before it is connected to the power supply. Ungrounded equipment can be lethally dangerous. Never perform any hot-line operation. Strong RF signals are harmful to human health. Ensure that the transmit antennas are shut down before an antenna installation or maintenance operation on a tower or mast installed with multiple transmit antennas. During an operation involving optical cables, keep your eyes far away from optical output ports and do not directly look at the optical output ports with bare eyes. Take measures to prevent dusts from entering your respiratory tract or eyes when drilling holes. Before connecting cables to storage batteries, disconnect the storage batteries from the power supply. Otherwise, injuries may be incurred. When working aloft, take measures to prevent objects from falling.
Equipment SafetyBefore operating the equipment, check the electric continuity of the equipment that requires grounding to ensure that it is reliably grounded. The static electricity produced by human body may damage the static-sensitive components, such as LSI on boards. Take proper ESD prevention measures, for example, wear ESD wrist straps or gloves to prevent boards, modules, and electronic components from being destroyed by static of the human body. When operating storage batteries, prevent battery short-circuiting and electrolyte overflow or leakage. The electrolyte corrodes metal objects and the boards, producing rust and causing board short-circuiting.

Mandatory /OptionalMandatory Mandatory
Full Configuration2 4
Installation SlotS6 and S7 S0 to S3
Preferentially configured in S7. The WBBP is installed in S3 by default. If extension CPRI ports are required, the board is installed in S2. If extension CPRI ports are not required, the priority of the installation position of the board is from s0 to S1, and then to S2.
FAN PWR1 and PWR2 PWR1 S0/S1/S4/S5
Configured in FAN slot. Preferentially configured in PWR2.
Preferentially configured in PWR1. The priority of the UTRP installation position of the board is from S4 to S5, and then to S0 and S1. -
S1 or S0
The UELP and UFLP need to be optionally configured in the BBU or SLPU on site according to the field requirements.

2. Slide the BBU case into the cabinet.
1. Install power cable.Connect the OT terminal of the power cable to the LOAD3 terminal of the PDU, and then fix the 3V3 connector of the power cable to the UPEU port on the BBU.
LOAD3 NEG(-) RNT(+)
The power cable is to be made depending on field requirements.
Installing the BBU in the APM30 dInstalling the BBU cables2. Install optical cables.Connect the longer end of the optical cable to the CPRI port on the WBBP. Then, connect the other end to the RRU.
Turn the puller on the optical module outwards, insert the optical module into CPRI ports. Turn outwards the puller on the optical module.

Remove the dustproof caps from the optical connectors. Insert the optical connector at one end of the CPRI optical cable into the optical module. lead the CPRI optical cable out of the cabinet along the left side of the cabinet.
Wrap the fiber tail with the winding pipe till the first cable tie.Connect the fiber tails labeled 1A and 1B to the CPRI_W port on the RRU. Connect the fiber tails labeled 2A and 2B to one of the CPRI ports on the WBBP

3Install the E1 transfer cable.Fix one end of the E1 transfer cable to the INSIDE port on the UELP. Fix the other end to the E1/T1 port on the WMPT.
4Install the E1 cable.Cabling the E1 cable. Fix one end of the E1 cable to the OUTSIDE port on the UELP. Strip the jacket off the E1 cable near the grounding point at the lower right corner of the cabinet to expose the shielding layer.Shielding layer of the E1 cable (25mm)
E1 transfer cable
Thread the FE cable through the grounding clip. Then, tighten the screw on the grounding clip to make the shielding layer of the FE cable in full contact with the grounding clip. Finally, connect the PGND cable on the grounding clip to the grounding bolt of the APM30.Shielding layer of the FE cable
Ensure that both ends of the E1 cable are disconnected. Then, weld connectors to the bare wires at one end of the E1 cable all at once.
