6-6 1X SC480 BTS Hardware Installation, Optimization/ATP, and FRU MAY 2004

PRELIMINARY

Refer to Figure 6-2 and the WinLMF Help function on–line

documentation for additional information on the layout of

the WinLMF directory structure (including CDF/NECF file

locations and formats).

NOTE

BTS System Software

Download

BTS system software must be successfully downloaded to the BTS

processor boards before optimization can be performed. BTS operating

code is loaded from the WinLMF computer terminal.

The BTS is configured for Circuit Backhaul and uses bts.cdf files. BTSs

configured for Packet Backhaul use bts.necf files (bts–xxx.xml) located

on the OMC–R.

Before using the WinLMF for optimization/ATP, the

correct bts–#.cdf (or bts–#.necf) and cbsc–#.cdf files for

the BTS must be obtained from the CBSC and put in a

bts–# folder in the WinLMF. Failure to use the correct

CDF/NECF files can cause wrong results. Failure to use

the correct CDF/NECF files to log into a live (traffic

carrying) site can shut down the site.

NOTE

The CDF/NECF is normally obtained from the CBSC on a DOS

formatted diskette, or through a file transfer protocol (ftp) if the

WinLMF computer has ftp capability. Refer to the WinLMF Help

function on–line documentation for the procedure.

Site Equipage Verification

If you have not already done so, use an editor to view the CDF/NECF,

and review the site documentation. Verify the site engineering equipage

data in the CDF/NECF matches the actual site hardware using a

CDF/NECF conversion table.

Use extreme care not to make any changes to the

CDF/NECF content while viewing the file. Changes to the

CDF/NECF can cause the site to operate unreliably or

render it incapable of operation.

Always wear a conductive, high impedance wrist strap

while handling any circuit card/module to prevent damage

by ESD. Extreme care should be taken during the removal

and installation of any card/module. After removal, the

card/module should be placed on a conductive surface or

back into the anti–static bag in which it was shipped.
