This Section contains information to assist troubleshooting of the SX-508 DPABX (Digital Private Automatic Branch Exchange). The SX-50 system is itself the most important tool in the troubleshooting process. It contains an array of diagnostic tests and equipment status displays to assist maintenance personnel. 1.1 This section has been reissued to incorporate MS55 software. 1.2 This Section uses the following approach to determining the cause of a malfunction: * ACQUIRE relevant information (i.e., who experiences the problem, when, and what they are trying to do) * CLARIFY problem (which features, equipment involved) 0 CONFIRM the problem through testing * ISOLATE the problem by tests of suspect equipment 9 CORRECT the problem 0 DOCUMENT the problem. 1.3 Unless otherwise stated, the operation and use of the Control Card and the Control Card 2 (MCC2) are identical, therefore this Section refers to them collectively as the “Control Card”. 9104-091-350~NA Issue 5 Revision 0 350 l-l

,’ 2.1 Each line or trunk circuit has an associated red status LED on the front face of the circuit card. The SX-50 cover must be removed to see these displays. See Table l-1 and Figure 2-i. 2.2 Each card has a green status LED on its front face located just above the red circuit status LEDs. The SX-50 cover must be removed to see these displays.
