TROUBLESHOOTING
6.1 OVERVIEW
A problem with the XC1000 can be diagnosed in a variety of ways. The
most common methods are as follows:
Startup fault isolation.
Use the procedures in this chapter to
troubleshoot problems that occur during startup. Problems that might
occur during the following startup sequences are described:
Power-on sequence
CPU tests
File-card status
Line-configuration tests
Alarm indications.
XC1000 alarms are activated by software or
hardware malfunctions. An analysis of the current alarm status is
described in this chapter. Three major types of alarms can be set:
Out-of-service (OOS) alarms
Service-affecting (SA) alarms
Non-service-affecting (NSA) alarms
Alarm indications are also shown by LEDs on the front edge of each logic
card or drive. Refer to section 5.2 for information about accessing and
printing the current alarm-status menu (menu 13.8). Audible alarms can
also be set.
External diagnostic tools.
External diagnostic tools can be accessed
remotely for troubleshooting, as follows:
Remote alarm relays
Remote diagnostic administrative terminal (RDAC)
Switching control center system (SCCS) interface
Status log entries.
The software in XC1000 can detect and report the
status of a variety of conditions. Refer to Chapter Seven for detailed
information about the status codes in the status log. Refer to section
5.2 for information about accessing and printing the status log.
Refer to Appendix C for trouble-escalation procedures.
6.2 STARTUP FAULT ISOLATION
When a XC1000 is started up, the startup sequences are monitored at the
SMT. Procedures for correcting problems encountered during startup are
provided for the following startup sequences:
Power-on
CPU tests
File-card status
Line-configuration tests
