2DBS3900 Monitoring SystemAbout This Chapter

The DBS3900 monitoring system enables monitoring of all boards and components in the

cabinet. If any board or component is faulty, an alarm is automatically reported. The UPEU and

UEIU in the BBU or the RRU collects monitoring signals from boards and components to

achieve environment monitoring of the DBS3900.

2.2 BBU Monitoring Port

2.3 Monitoring Principles of the Cabinets

The DBS3900 cabinet is monitored by various boards. The boards collect alarms from sensors

and fans, and then transmit the alarm signals to the MON port on the BBU through the RS485

serial bus. In this manner, the boards monitor the cabinet.

2.1 Customized Alarm Input

If a BBU monitors customer devices, customized alarms about the devices must be reported to

the 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 the

related initial configuration guide.

Monitoring Board Configuration

If a BBU monitors customer devices, customized alarms about the devices must be reported to

the BBU. The configurations of monitoring boards in the BTS3900A depend on the number of

customized 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 two

UPEUs or UPEU+UEIU can be configured for the BBU, which means there are 16 Boolean

alarm inputs. This method can be used for the configuration of less than 16 customized alarm

inputs.

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.

Customized alarm signals are transmitted to the IN0 to IN3 ports on the USLP2 in the SLPU

and then transferred to the EXT_ALM port on the UPEU or EUIU through the alarm cable for

the BBU. Table 2-2 describes the relationship between the IN0 to IN3 ports and the number ofcustomized alarms.

For details about ports on the USLP2, see 5.8.5 USLP2. For details about the wire sequence of

the BBU alarm cable, see 4.16 BBU Alarm Cable.

NOTE

The SLPU is configured with two USLP2s by default before delivery when it is used as an alarm signal

protection 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 EMUA

The EMUA can be configured for the DBS3900 that requires more than 16 Boolean alarm

signals. Each EMUA supports 32 Boolean alarm inputs and two RS485 signal inputs.

Customized alarms are transmitted to the EMUA that connects to the PMU. Then, the PMU

reports the alarms to the CMUA, which transfers the alarms to the BBU through the MON port.

For details about cable connections, see Figure 2-2.

If the CPRI port on the RRU is not used to report alarms to the BBU, the serial port on the RRU

is used to report alarms to the CMUA that connects to the PMU. Then, the PMU transfers the

alarms to the EMUA. For details about cable connections, see Figure 2-3.

The BBU houses the UPEU and UEIU for monitoring. Each board has two Boolean input ports

and two RS485 input ports, and each Boolean input port receives four Boolean inputs. Figure

l Provides the CPRI interface for communication between the BBU and the RRU or RFU,

and supports the CPRI interface in 1+1 backup mode.

l Processes uplink and downlink baseband signals.

l The WBBPd supports interference cancellation (IC) within the board.

l When installed in slot 2 or slot 3, the WBBPd supports the IC function of uplink data.

3.2.5 UPEU

The Universal Power and Environment Interface Unit (UPEU) is a mandatory board of the

BBU3900. It converts -48 V or +24 V DC power to +12 V DC power.

Panels

The UPEU is classified into the Universal Power and Environment Interface Unit Type A

(UPEUA) and the Universal Power and Environment Interface Unit Type B (UPEUB). The

UPEUA converts -48 V DC power to +12 V DC power and the UPEUB converts +24 V DC

power to +12 V DC power. Figure 3-12 shows the UPEUA panel and Figure 3-13 shows the

UPEUB panel.

The UPEU performs the following functions:

l Converts -48 V DC or +24 V DC power to +12 V DC power that is applicable to the boards

l Provides two ports for two RS485 inputs and two ports for eight Boolean signals

l Provides reverse connection protection for power cable connectors

l If two UPEUs are configured, two power inputs are required. The UPEU in slot 19 works

in active mode, and the UPEU in slot 18 works in standby mode

LEDs

The UPEU has one LED that indicates the operating status of the board. Table 3-13 describes

the LED and its status.
