Maintenance Strategy Maintenance Strategy The maintenance strategy presented in this section is only a guideline, not a fixed procedure. Refer to Figure 1-7 whenever you are uncertain as to how to proceed. As you become more experienced with maintaining and troubleshooting the system, you will most likely develop your own strategy.
Page 337 Maintenance Strategy Trouble Reports System trouble can be reported in two ways: By users By system alarms (permanent errors) Automatic Tests The system performs ongoing maintenance automatically by running tests t h a t : Monitor the status of equipment. Audit operations consistency.
Page 338: Clearing Alarms
Maintenance Strategy If a software installation or upgrade is taking place, a blinking character is displayed to indicate the status of the procedure. See "Forced Installation of System Software” in Chapter 4 for more information. The status display indicates an alarm (on an MLX-20L console or a PC running SPM), and can be viewed on the Error screen.
Page 339 Maintenance Strategy Warm Start A loss of power for less than 250 ms can cause a warm start. If this occurs, calls in progress are not dropped, but calls in the process of being connected may be dropped. Considerations Power interruptions of less than 100 ms usually do not affect the system.
Page 340 Maintenance Strategy Frigid Start (System Erase) CAUTION: All system programming is erased. When you perform a frigid start (System Erase), all calls are dropped, and the system configuration information is erased. All system memory must be reinitialized, including system programming. Then the entire system must be rebooted. To perform a frigid start, select as follows: System Erase...
