### Revision Transmittal Sheet Date: July 11, 2002 Revision 2: October 12, 2006 ATA System: 2339 SUBJECT: COMMUNICATIONS - Cabin Management System (CMS) - Change the Operational Software

This revision includes all pages of the service bulletin. COMPLIANCE INFORMATION RELATED TO THIS REVISION Revision 2 - More work is necessary on airplanes changed as shown in the initial release and in Revision 1 of this service bulletin. Airplanes with Overhead Electronics Unit (OEU) hardware 285W0029-5 installed must install OEU Operational Program Software (OPS). REASON FOR REVISION This revision is sent to add an instruction to install OEU OPS for the configuration that has OEU hardware part number 285W0029-5 installed. This instruction was omitted in the initial release and Revision 1 of this service bulletin. In Work Instructions, Paragraph 3.B a new step 6 is added. Also, in Summary Manpower and in paragraph 1.G, manpower estimate is changed. Paragraph 1.A., Effectivity, shows changes of airplane operators. Each operator should examine the Effectivity paragraph for changes. Vertical lines are put on the left edge of each page, except in Paragraph 1.A., Effectivity, to show the location of important changes. Pages with no vertical lines have no important changes.

### Summary Date: July 11, 2002 Revision 2: October 12, 2006 ATA System: 2339 SUBJECT: COMMUNICATIONS - Cabin Management System (CMS) - Change the Operational Software

CONCURRENT REQUIREMENTS The related Boeing component service bulletin is 285W0925-23-02. BACKGROUND Boeing Service Related Problem (SRP) 777-SRP-24-0091 is related to this service bulletin. The change described in this service bulletin will change the operation of cabin lighting system when the CABIN/ UTILITY switch is installed. Smoke and flames in the cabin passenger can cause injury to passengers and damage to the safety-critical cabin equipments. We have received numerous reports of smoke or flames in the passenger cabin related to the wiring for the passenger cabin in-flight entertainment system, cabin lighting and passenger seats. It is not easy to remove the electrical power to these systems to stop the smoke and flames. A CABIN/UTILITY switch can be installed to remove power to some systems in the passenger cabin. This change to the cabin services system (CSS) operational software (OPS) will change the way various lighting systems operate when the switch is set to "OFF". When the CABIN/UTILITY switch is set to OFF, all night lights, reading lights and attendant work lights will come on. Commands from the attendant switch panel for night light operation will be ignored. A message will be shown on the cabin control panels which says "REDUCED POWER CONDITION - Fluorescent lights may be off. Night lights are locked on". This message replaces the Function Lock-Out - Reduced Power pop-up screen. When the CABIN/UTILITY switch is set to ON, control of the cabin lighting systems by the cabin control panels is put back to normal and the REDUCED POWER CONDITION message is removed. The cabin control panels will show the state of the CABIN/UTILITY switch on the Input Monitor - ARINC 629 Bus screen. ACTION (PRR 61887K) Replace the mass memory card (MMC) with a new card with the new CSS OPS. Install a new OPS in the Cabin Area Control Panel (CACP), Zone Management Units (ZMU) and the Cabin System Management Unit (CSMU). Make a change to the CSS configuration database (CDB). Install the new database in the CSS components.July 11, 2002 Revision 2: October 12, 2006 777-23-0175 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 8 of 20
