BBU3900Hardware Description About This Document


iii

The DBS3900 monitoring system enables monitoring of all boards and components in thecabinet. If any board or component is faulty, an alarm is automatically reported. The UPEU andUEIU in the BBU or the RRU collects monitoring signals from boards and components toachieve environment monitoring of the DBS3900.

3 BBU3900 Equipment

This describes the BBU3900 equipment. It is a baseband unit that implements communicationbetween the NodeB and the RNC.

4 BBU3900 Cables

This describes the BBU3900 cables. The cables are the PGND cable, power cable,E1 cable, E1surge protection transfer cable, FE cable, FE surge protection transfer cable, Iub optical cable,monitoring signal cable between the APMI and the BBU, CPRI optical cable, alarm cable,EMUA signal cable, monitoring signal cable between the CMUA and the BBU, and GPS clocksignal cable.

2 DBS3900 Monitoring System

About This Chapter

The DBS3900 monitoring system enables monitoring of all boards and components in thecabinet. If any board or component is faulty, an alarm is automatically reported. The UPEU andUEIU in the BBU or the RRU collects monitoring signals from boards and components toachieve environment monitoring of the DBS3900.

2.1 Customized Alarm Input

2.2 BBU Monitoring Port

2.3 Monitoring Principles of the CabinetsThe DBS3900 cabinet is monitored by various boards. The boards collect alarms from sensorsand fans, and then transmit the alarm signals to the MON port on the BBU through the RS485serial bus. In this manner, the boards monitor the cabinet.

BBU3900Hardware Description 2 DBS3900 Monitoring System


2-1

2.1 Customized Alarm InputIf a BBU monitors customer devices, customized alarms about the devices must be reported tothe BBU in the following two modes:

l The alarms are collected by the UPEU or UEIU in the BBU.

l The alarms are collected by the EMUA. For details about software configurations, see therelated initial configuration guide.

Monitoring Board Configuration

If a BBU monitors customer devices, customized alarms about the devices must be reported tothe BBU. The configurations of monitoring boards in the BTS3900A depend on the number ofcustomized alarms, as listed in Table 2-1.

NOTE

l If backup power is required for the BBU, two UPEUs rather than UPEU+UEIU are configured.

l The analog values can be monitored only by the EMUA.

l Two USLP2s and one SLPU are delivered in a package.

l The EMUA with sensors is configured according to site requirements for the indoor DBS3900.

Customized Alarms Collected by the UPEU or UEIU

Each UPEU or UEIU in the BBU supports eight Boolean alarm inputs. A maximum of twoUPEUs or UPEU+UEIU can be configured for the BBU, which means there are 16 Booleanalarm inputs. This method can be used for the configuration of less than 16 customized alarminputs.

If using this method, connect the device to be monitored to the SLPU for surge protection, andthen connect the device to the EXT_ALM port on the BBU, as shown in Figure 2-1.

Figure 2-1 Customized alarms collected by the UPEU or UEIU

Customized alarm signals are transmitted to the IN0 to IN3 ports on the USLP2 in the SLPUand then transferred to the EXT_ALM port on the UPEU or EUIU through the alarm cable forthe BBU. Table 2-2 describes the relationship between the IN0 to IN3 ports and the number ofcustomized alarms.

NOTEThe SLPU is configured with two USLP2s by default before delivery when it is used as an alarm signalprotection unit. If a BBU is configured with one UPEU, the UPEU must be installed only in the lower slot.In this case, the USLP2 in the upper slot of the SLPU is not used.

Customized Alarms Collected by the EMUAThe EMUA can be configured for the DBS3900 that requires more than 16 Boolean alarmsignals. Each EMUA supports 32 Boolean alarm inputs and two RS485 signal inputs.

4.3 BBU Power CableThis section describes the BBU power cable. Either -48 V power cable or +24 V power cablecan be used, depending on the power supply scenario.

Exterior

The BBU power cable depends on the type of the cabinet containing the BBU, because differenttypes of cabinet use different power supplies.

When the power supply device is the DCDU or PDU, the BBU power cable has a 3V3 connectorat one end and bare wires at the other end. Based on the connector of the power distributiondevice, appropriate terminals are added to the bare wire end on site. Figure 4-2 shows the BBUpower cable with OT terminals at the bare wire end as an example.

optical cable is required. When the distance between the BBU and the RRU is longer than 100m, a single-mode optical cable is required. A single-mode optical cable connects the BBU to theODF and the ODF to the RRU to transmit CPRI signals.

A multi-mode optical cable is a multi-mode cable with a DLC connector at each end. Figure4-13 shows the multi-mode optical cable.

Figure 4-13 Multi-mode optical cable

(1) DLC connector (2) Branch cable (3) Label on the branch cable

When a multi-mode optical cable is used for connection between the BBU and RRU, the branchcables on the BBU side and RRU side are 0.34 m and 0.03 m long respectively. When a multi-mode optical cable is used for connection between RRUs, the branch cables on both RRU sidesare 0.03 m long.

A single-mode optical cable has a DLC connector at one end and two FC connectors at the otherend, as shown in Figure 4-14.

When a single-mode optical cable is used for connection between the BBU and the ODF, thebranch cables on the BBU side and ODF side are 0.34 m and 0.8 m long respectively.

When a single-mode optical cable is used for connection between the ODF and RRU, the branchcables on the BBU side and ODF side are 0.03 m and 0.8 m long respectively.

NOTEThe CPRI optical cable must be connected to the optical module in the CPRI port on the BBU or RRU. Themulti-mode optical cable and single-mode optical cable are used for the multi-mode optical module and single-mode optical module respectively.
