Installing the PGND Cablesa

External ground barExternal ground bar

1. Install the PGND cable for the -48 V or 220 V cabinet.

2. Install the PGND cable for the +24 V cabinet.

If the cabinet is installed with the power subrack before delivery, you should remove the power subrack from the cabinet and also the power cable between the power subrack and the DCDU-01 and PGND cable for the power subrack before tightening bolts. After the cabinet is installed, install the power subrack, related power cable, and related PGND cable.

The cabinet door can be removed before the cabinet is installed for easy operations.

Installing the E1 Cablea

E1 cable or FE cable can be configured according to the transmission mode of the base station. Only one transmission mode is supported by the base station working in the GSM standard, and two transmission modes can be supported by the base station working in the UMTS standard. For details about the configurations and cable connections, see the BTS3900 Hardware Description.

For a multi-mode base station, only SRAN5.0 supports the LTE mode.

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.E1 transmission in the GSM standard E1 transmission in the UMTS standard

The methods for routing RF jumpers in a single cabinet and in cabinets installed side-by-side are the same. The cover plate of the upper cabinet must be removed before the RF jumpers are installed in stacked cabinets.

Remove the cover plate.

Color RingSectorSystem

Attach color rings by referring to the following table.

If main and diversity are not distinguished, the RF signals transmitted from the left RF unit are regarded as the main signals by default, and the RF signals transmitted from the right RF unit are regarded as the diversity signals.

If an antenna system serves six sectors, the colors of the rings for sectors 4, 5, and 6 are purple, orange, and green respectively.

Insulating tape

The waterproof tape should be wrapped for an extra length of 20 mm away from the connectors at both ends.

The tapes should be wrapped around the connector from the lower part to the upper part. When wrapped for another layer, the tapes may not be cut.

When wrapping the waterproof tape, ensure that the upper layer of the tape covers at least 50% of the lower layer.

The insulating tape should be wrapped for an extra length of 20 mm away from the waterproof tapes at both ends.

Extend the tape.
