2.00 Clearing System-Detected
Troubles
2.01 Introduction
Most system-detected troubles are reported via
the alarm LED (light-emitting diode) indicators
located on the top shelf, each circuit card,
Attendant Console and PITS. The following
covers general trouble-clearing techniques and
recommended procedures for identifying and
clearing a variety of specific system troubles.
You can detect, report, and clear troubles in the
following three ways.
(1) Error Log
(2) LED indicators on the Main Units
(ALARM LED on the Top shelf, LEDs on the
cards)
(3) User-Reported Error
(Including Automatic Failure Reporting, Local
Alarm, Remote Alarm)
2.02 Consulting the Error Log
Consulting the error log should be the first step in
diagnosing system-related troubles.
The error log is read by logging in to the system
administration terminal, selecting the Main Menu
item "3. Monitor," and then selecting "1. Error
Log."
Refer to Section 14-G-2.00 "Error Log Screen."
The error log is comprised of the following two
error tables.
Error Log (1/2) (Major and Minor Alarms)
Error Log (2/2) (Light Alarms)
Each error record is reported as one line on the
screen.
Error Log (1/2) and Error Log (2/2) use the same
format and exist independently.
These error records provide the location of the
error, the date and time of the occurrence, and a
description of the error.
A typical error record from the error log is as
follows:
Error Log (1/2)
MAR-20-90 8:39 AM MAJOR ALARM #0400 Basic shelf power down
1 2 3
14-D-4
This record is interpreted as follows:
1. The year, month, date and time of the
occurence.
2. The severity of the error
MAJOR ALARM-Error Log (1/2)
MINOR ALARM-Error Log (1/2)
Blank-Light Error-Error Log (2/2)
3. Error Code
Each error record has a specific error code.
You can clear the troubles via the
troubleshooting guide corresponding to the
error code.
(Refer to Section 14-E-3.00 "Troubleshooting
via Error Log Records.")
4. Description
A description of the nature of the error.
