Number: 777-23-0141 

## Summary Date: June 14, 2001 ATA System: 2339

SUBJECT:COMMUNICATIONS - Cabin Management System - Software Changes

CONCURRENT REQUIREMENTS For all airplanes except WB077 and WB078, you cannot make the changes given in this service bulletin unless the changes given in Boeing Service Bulletin 777-23-0143 are made. The changes given in Boeing Service Bulletin 777-23-0143 were made on airplanes WB077 and WB078 before delivery. BACKGROUND This service bulletin gives instructions to change the operational program software (OPS) for the cabin system control panel (CSCP), the cabin area control panel (CACP), and the cabin system management unit (CSMU). The new software will prevent the seat power control buttons on the CSCP and CACP from becoming disabled during loadshed conditions. The new software will also shut off the fluorescent backlights for the CACP and CSCP touchscreens while the screen saver is active to increase lamp life. A panel with the new software will make a "beep" sound when the panel comes out of screen saver mode. An operator reported that, during a partial loadshed condition, they were unable to turn off power to the seats. During loadshed conditions, the electrical load management system (ELMS) controls power to the seats and the seat power control buttons on the CSCP and CACP are disabled. As a result, the power to the seats cannot be controlled by the operator. The new software changes the cabin management system to enable the seat power control buttons during loadshed conditions. ACTION(PRR 61877-1) At the CSCP, remove the old CSCP, CACP and CSMU operational program software (OPS) from the CSCP mass storage. Install new OPS to the CSCP mass storage and to the CSCP, CACPs and CSMU. Reinstall the configuration database. Do a configuration check to make sure the correct OPS and configuration database are installed.
