Thereafter, as the equipment is powered-up, all startups are monitored. In cases of older software the commissioning engineer has to load the latest or certified software into those units. The units are brought up in their respective order of software loading process and the faulty units can be spotted by checking for faulty light emitting diode (LED) colours for replacement. Figure A.5 shows a commonly followed checklist for a BSC unit. A.3.4 Inspection and Alarm Testing The plug-in units are run through diagnostic tests to ascertain their individual hardware integrity and unit stability. After the units are tested, a complete power-off test is done in order to check the uniformity of the equipment parts, working in unison. Redundant units and switchovers are checked by manually separating the working units from their normal state of operation. Minor fault conditions are simulated in order to check the generation of basic alarms. When there are many subelements of the equipment, individual units, their port connection and interconnectivity are also checked. Figure A.6 shows a checklist of some common alarms. A.3.5 Parameter Finalisation All data and parameters are consolidated before the integration process starts. Network planners prepare the data sheets from the inputs they receive from the various vendor and operator teams. The integration process cannot be started without them, even though the site is ready and the equipment is working in a stand-alone m
