Indicator Color Status Meaning

Blinking (on for

1s and off for 1s)

Alarms are generated. The alarms may be

caused by the faults on the related boards or

ports. Therefore, you need to locate the fault

before deciding whether to replace the

module.

Steady off No alarm is generated.

ACT Green Steady on The module is running properly with TX

channels enabled or the software is being

loaded without RRU running.

Blinking (on for

1s and off for 1s)

The module is running properly with TX

channels disabled.

VSWR Red Steady off No Voltage Standing Wave Ratio (VSWR)

alarm is generated.

Blinking (on for

1s and off for 1s)

VSWR alarms are generated on the

ANT_TX/RXB port.

Steady on VSWR alarms are generated on the

ANT_TX/RXA port.

Blinking (on for

0.125s and off for

0.125s)

VSWR alarms are generated on the

ANT_TX/RXA and ANT_TX/RXB ports.

CPRI0 Red or

green

Steady green The CPRI link is functioning properly.

Steady red An optical module fails to transmit or receive

signals because the optical module is faulty

or the fiber optic cable is broken.

Blinking red (on

for 1s and off for

1s)

The CPRI link is out of lock because of a

failure in clock lock between two modes or

mismatched data rates over CPRI ports.

Steady off The optical module cannot be detected, or the

optical module is powered off.

CPRI1 Red or

green

Steady green The CPRI link is functioning properly.

Steady red An optical module fails to transmit or receive

signals because the optical module is faulty

or the fiber optic cable is broken.

Blinking red (on

3.4 Installation Scenarios

An RRU can be installed on a pole, U-steel, angle steel, or IFS06. Installation scenarios must

meet heat-dissipation and waterproofing requirements of the RRU.

Requirements for the Installation Scenarios

Application scenarios:

To ensure proper heat dissipation of the RRU, the following requirements must be met:

l The RRU cannot be installed in an enclosed cabinet without a cooling system.

l The RRU cannot be installed in an enclosed camouflage box.

l The RRU cannot be installed in an enclosed equipment room without a cooling system.

l When multiple RRUs are installed in centralized mode, the minimum clearance

requirements must be met. For details about the minimum clearance requirements, see 3.5.2

Clearance for Multiple RRUs and 3.5.3 Installation Spacing Between RRUs.

CAUTION

In improper installation scenarios, the heat dissipation efficiency decreases and therefore the

RRU may not work properly. Figure 3-4 shows an improper installation scenario.

Figure 3-4 Improper installation scenario

Method of installation:

l To ensure proper heat dissipation and waterproofing of the RRU, the RRU must be installed

with the ports at the bottom and the vertical deviation angle of the RRU must be less than

or equal to 10 degrees, as shown in Figure 3-5.

l The side-mounted mode is recommended for RRUs on the main pole secured on a tower.

This installation mode allows multiple RRUs to be installed next to each other at the same

level on a pole. When the horizontal distance between the main and auxiliary poles on a

tower is equal to or greater than 810 mm (23.62 in.), the side-mounted mode is

recommended for installing RRUs on the auxiliary pole to meet the minimum clearance

requirements. Otherwise, the standard mode is recommended for installing RRUs on the

auxiliary pole.

Figure 3-5 Requirements for the vertical deviation angle of an RRU

(1) RRU (2) Installation support (pole, U-steel, angle steel, or wall)

Installing an RRU on a Pole

Figure 3-6 shows the diameter of a pole for installing an RRU.

Figure 3-6 Diameter of a pole

CAUTION

l The diameter of a pole for installing an RRU ranges from 60 mm (2.36 in.) to 114 mm (4.49

in.). The recommended diameter is 80 mm (3.15 in.).
