Chapter 2 Commissioning Hardware


Hardware Commissioning covers the following procedures:

z Verifying Hardware Installationz Verifying DIP Switch and Jumper Settingsz Verifying VSWR of Antenna and Feeder Systemz Checking Macro NodeB Power-onz Checking Mini NodeB Power-on

Caution:

Pay attention to the following items during hardware commissioning:z Wear an antistatic wrist strap before installing boards and modules.z Do not leave boards and modules anywhere after taking them out of the packing material. Insert

them loosely in their corresponding slots before power-on check. Secure them with screws after the

power-on check.z For macro NodeBs, secure NodeB dual duplexer & low-noise amplifier modules (NDDL) before

installing antenna and feeder jumpers.z For macro NodeBs, do not install NDDLs or NodeB linear power amplifier modules (NLPA) upside

down. Otherwise, damage might be done to the modules.z For mini NodeBs, check the level degree of a module after installing it by placing two level bars

perpendicular to each other on the subrack top plane. If the level error is over five degrees, it is

necessary to adjust its position.z For outdoor installation, install a sunshade on the plastic shell of the cabinet.

Verify the settings of macro NodeB DIP switches and jumpers as follows:

1) Pull out the installed NDTI/NAOI, verify DIP switches on NodeB digital trunk

interface units (NDTI) and NodeB ATM optical interface units (NAOI)

Notes:

The E1/T1 ports of NDTIs and NAOIs may work in the balanced or unbalanced mode. By default, they

work in the unbalanced mode. That is, the default transmission cables are 75- coaxial ones. For more

details about NDTI and NAOI DIP switch settings, refer to WCDMA NodeB Hardware Description Manual

Boards.

2) Insert the NDTI/NAOI back into the slots according to the data configuration.

3) Verify uplink (UL) jumpers and downlink (DL) jumpers on NodeB radio frequency

backplane (NRFB)

Notes:

z The jumpers on the NRFB are set before delivery. You can reconfigure them if the NodeB

configuration type change. For more details, refer to WCDMA NodeB Hardware Description Manual

Cabinets and Cables.z The NRFP DL jumpers and UL jumpers are on the NRFP front where NTRXs and NDDLs are

5.3 Verifying Clock Source

5.3.1 Overview

This procedure is to verify the clock source status.

5.3.2 Procedures

Verify clock source status as follows:

1) Select the clock source for the NodeB according to the following rules:z Select GPS reference source if the NodeB is equipped with GPS.z Select the external reference source if the NodeB is configured with an external

reference source instead of a GPS and if the precision of the external referencesource meets the requirements.

z Select Iub reference source if the NodeB is configured with neither GPS nor an

external reference source.

Notes:

z External clock source may be a 2 MHz clock, such as the synchronization interface of SDH or BITS.z The precision of the reference source must be no less than 0.05 ppm.

2) When selecting the Iub reference source, specify an E1/T1 of the Iub interface

from which the NodeB extracts clocks. Carry out the MML command ADD

IUBCLK on NodeB O&M system to select an E1/T1 that connects to the RNC.

Notes:

Display the E1/T1 selected as Iub clock through the MML command DSP IUBCLK on the NodeB O&M

system.

3) Set work modes of the clock by the following two rules:z Set the clock work mode to "free" through the MML command MOD CLKMODE

on the NodeB O&M system to prevent the alarm of abnormal clock source if the

precision of the reference source cannot meet corresponding requirement.z Set the clock work mode to "phase-lock" through the MML command MOD

CLKMODE on the NodeB O&M system if the precision of the reference source

satisfies the corresponding requirement.


39/73


5-3

Notes:

Display the clock work mode through the MML commandDSP CLKon the NodeB O&M system.

When the reference source is normal, phase-lock speed of the clock varies with the reference sources

as follows:z When the NodeB traces Iub clock, it locks the reference source within one and a half hours.z When the NodeB traces GPS clock, it locks the reference source within 36 minutes.z When the NodeB traces the external clock, it locks the reference source within six minutes.

The phase-lock speed of the clock does not affect normal services.

4) Start clock quality test through MML command STR CLKTEST on the NodeB

O&M system to display the difference between the NodeB clock and reference

source.z If the difference is a negative value, it means the NodeB clock is slower than the

reference clock.z If the difference is a positive value, it means the NodeB clock is faster than the

reference source.z Under most cases when the precision of the reference source meets the

requirement, the difference is zero.

5) Stop the clock quality test through the MML command STP CLKTEST on the

NodeB O&M system.

antenna and feeder system so that the total gain from the antenna port to the NDDLis zero.

6.4.2 Procedures

Verify the NDDL attenuation value as follows:

1) Calculate the uplink gain of the antenna and feeder system.z Figure 6-1 simplifies the connection between components of the antenna and

feeder system.

Note:

L1,L2 and L5 are loss of jumper. L3 is loss of feeder. L4 is loss of lightning arrester.G1 is gain of TTA.

z The uplink gain of the antenna and feeder system is calculated in the following

formula:

G(dB)=G1L1L2L3L4L5

z In practice, the NDDL Unit Attenuation closely relates to the engineering

installation. Currently, the TTA gain G1 is 12 dB, the lightning arrester loss L4 is

0.1 dB. Table 6-1 lists the loss of corresponding jumpers and feeders.

Table 6-1 Component loss of antenna and feeder system

1 1.5 m 1/2" jumper 0.3 dB Both ends are DIN male connector.



4 7/8" feeder 6.11dB/100m Both ends are DIN female connector.

5 5/4" feeder 4.43dB/100m Both ends are DIN female connector.

2) Determine the NDDL Unit Attenuation value according to the value range of G:z When there is a TTA and the value of G is no less than 6, the TTA switch must

be set to "ON", and the NDDL unit attenuation value to G.z When there is a TTA and the value of G is less than 6, the TTA switch must be

set to "ON", and the NDDL Unit Attenuation value to 6.

Caution:

Before hardware installation, make a proper engineering plan to avoid the situation that the value of G isless than 6dB even if TTA is equipped.

z When there is no TTA in the antenna and feeder system, the value of G must be

less than zero. The TTA switch must be set to "OFF", and the NDDL Unit

Attenuation value to zero.

3) Query NDDL attenuating value through the MML command DSP NDDLTTA onNodeB O&M system. If the NDDL attenuation value is the value determined in

step 2), go to step 4). Otherwise, set the TTA switch and the NDDL Unit

attenuation value through the MML command SET TTASWNDDLATTEN on

NodeB O&M system.

4) Launch RTWP measurement on the NodeB O&M system. The RTWP

measurement result shall meet the conditions in step 5) in section 6.2 . If itdoes not meet the conditions, the possible causes might be as follows:

z Incorrect calculation of the gain of the antenna and feeder system leads to NDDL

attenuation setting error.z If the value of G is no more than 6 when there is a TTA installed for the antenna

and feeder system, the RTWP measurement result is obviously small. Try to

avoid this case in the engineering plan.z There is antenna and feeder installation problem. Check the hardware

installation of the antenna and feeder system according to WCDMA NodeB

Installation Manual Antenna & Feeder System Installation. z There is intra-frequency interference.

Chapter 7 Commissioning Downlink RF Channel


By calibrating DL RF channel gain of NodeB, you can:

z Clear the variance among boards.z Ensure that the power of RF transmit signals at the antenna port on the cabinet

top is consistent with the configured cell transmit power.

There are two methods to display the downlink transmit power:

z Method 1: Use RF measurement instruments to measure the power of RF

transmit signals at the antenna port on the cabinet top. The instruments include

E4445A, E4440, E4406, and YBT250. For more details, see appendix C.z Method 2: Display the total cell transmit power through the NodeB O&M system.

The total cell transmit power is calculated according to the detected power

reported by NLPA.

This section applies method 2 to calibrate RF downlink channel and covers the

following procedures:

z Calibrating DL RF Channel Gain of Macro NodeB Cellz Calibrating DL RF Channel Gain of Mini NodeB Cell

7.2 Calibrating DL RF Channel Gain of Macro NodeB Cell

7.2.1 Overview

This procedure is to calibrate the DL RF channel gain of a macro NodeB cell.

Caution:

If you employ indoor antennas, connect a large-power attenuator to the antenna connector on the

cabinet top to prevent radiation injury due to large-power microwave emitting.

The prerequisites for downlink RF channel commissioning includes:

z The NodeB antenna and feeder system is properly installed.z NodeB is working normally and the local cell is available.

7.2.2 Procedures

1) Deactivate the logical cell through the RNC MML command DEA CELL .

2) Create a 141 test on the NodeB O&M system.z Select the cell on the 141 test window.z Set the maximum transmit power of the cell to 44 dBm in the [Set Cell

Parameters] dialog box.z Select [DL Test Started/Start RF Test/DL Test/Maximum Transmit Power] from the

141 test window to start the Maximum Transmit Power test.

Caution:

Connect the antenna and feeder system to the cabinet before carrying out the DL test.

3) Carry out the MML command STR NLPAPWRMON on the NodeB O&M system.

The slot number of the NLPA must correspond to the cell being calibrated. The

system reports the output power of the NLPA in the display area, as shown in

Figure 7-1.
