Troubleshooting IMPORTANT NOTICE A. CORRECT SYSTEM GROUNDING IS CRITICAL. GROUNDING INSTRUCTIONS CONTAINED IN SECTION MlTL9108-093-ZOO-NA, SHIPPING, RECEIVING AND INSTALLATION MUST BE ADHERED TO WITHOUT EXCEPTION. NOTE THAT THE SYSTEM MAY FUNC- TION ERRATICALLY, OR NOT AT ALL WITHOUT PROPER GROUNDING. B. THE FOLLOWING POINTS SHOULD BE CAREFULLY NOTED AND THE INSTRUCTIONS THEREIN STRICTLY OBSERVED : l Handle circuit cards by the edges only, and ensure that a ground strap is used. Card damage may otherwise re- sult. 0 Before replacing a card, remove the original card, check for bent or damaged connectors, inspect the backplane, and reseat the original card. 0 If a problem has been cured through the replacement of a card, temporarily reinsert the original card to verify that the fault is located therein. 0 Always provide the maximum amount of relevant data on the card repair tag accompanying a faulty card (see Appendix F) - never return a card without a repair tag. e Ensure that a system fault record is always up-to-date, and kept on site. vii
Troubleshooting 1. GENERAL Introduction 1.01 This Section is intended to provide maintenance personnel with a comprehensive guide to the detection, analysis and correction of malfunctions of the SX-200@ DIGITAL PABX with Generic 1000 or Generic 1001 software. The scope of this Section the covers the main switching machine, the central office interface, stations and special sets, and AC power (including grounding). The Section comprises trou- bleshooting procedures, which are used to isolate and correct mal- functions, together with additional supporting information. 1.02 Before troubleshooting is attempted, the maintenance user should become very familiar with the SX-200@ maintenance system. A complete description of the maintenance system is provided in Section MlTL9108-093-353-NA. Further details concerning the maintenance of the SX-200@ DIGITAL PABX with Generic 1000 or Generic 1001 software may be found in the MITEL Sections listed in Table l-l. Reason for issue 1.03 New procedures have been added to cover new hardware.

Troubleshooting 2. PRIMARY TROUBLESHOOTING PROCEDURES General 2.01 Troubleshooting a malfunction in any complex electronic sys- tem is accomplished in a series of logical steps. This Section assumes the following basic steps in the troubleshooting of a mal- function: GATHERING of information CLARIFICATION of the problem CONFIRMATION of the problem ISOLATION of the problem CORRECTION DOCUMENTATION. Chart 2-l provides the basic primary troubleshooting flowchart for the SX-200@ DIGITAL PABX system. This chart acts as a starting point for the troubleshooting process, and directs the trouble- shooter to the appropriate detailed troubleshooting procedure. 2.03 The, troubleshooter, when investigating a problem, should con- tinually verify each step in the isolation process so as to ensure that the system, and the symptoms of the malfunction are clearly understood. This will ensure that the malfunction is accuratly cate- gorized so that appropriate diagnostics, where applicable, may be invoked. Page 24

Troubleshooting PROCEDURE 1 - MACHINE TOTALLY INOPERATIVE 0 General 2.04 When any switching machine is totally inoperative the prime requirement is the restoration of service to the system, or the part that has been affected. Chart 2-2 shows how to achieve this in the shortest possible time. Once service has been restored, the other procedures (see Chart 2-1) may be used to determine the cause of the failure. 2.05 Note that if power fail transfer has occurred, or it is necessary to invoke power fail transfer, toggle the POWER FAIL TRANSFER switches on the maintenance panel(s) to prevent lines and trunks from transferring back to the switch before it has been returned to oper- ational status.
