Organization

1 Preparations for Site Maintenance

The preparations for the maintenance of the BTS3702E site include obtaining site information, selecting maintenance tasks, and preparing maintenance tools and spare parts.

2 Tasks of Routine Hardware Maintenance

The tasks of the routine hardware maintenance of the BTS3702E include the maintenance of the power supply system and grounding system, the maintenance of the main equipment of the BTS3702E, and the maintenance of the cables.

3 Powering On and Powering Off the BTS3702E

When maintaining the BTS3702E, you need to power on and power off the BTS3702E. During power-on, check the power supply voltage of the BTS3702E and the states of the indicators on the BTS3702E. Power off the BTS3702E on a regular basis or in an emergency according to actual requirements.

4 Replacing the BTS3702E Modules

The BTS3702E is an integrated outdoor micro BTS of Huawei WiMAX Micro. Replacing the BTS3702E modules disrupts all services carried by this BTS.

5 Replacing the Optical Modules

The optical module provides an interface for photoelectric conversion, which enables the transmission between the BTS3702E and other equipment through the optical fiber. It is used to connect the ASN-GW or cascading connections between the BTSs. Remove the optical fibers first when replacing the optical modules. This disrupts the transmission signal.

6 Replacing the Power Modules

The power module is used to shift the power level to enable the transmission between the BTS3702E and other equipment through Ethernet cables. It is used to connect the ASN-GW or cascading connections between the BTSs. Remove the Ethernet cables first when replacing the power modules. This disrupts the transmission signal .

7 Replacing the BTS3702E Cables

When the BTS3702E cables are faulty, you need to replace them promptly. The cables that can be replaced are power cables, signal cables, transmission cables, and RF jumpers.
