Introduction
The purpose of maintenance is to detect, report, and clear problems quickly and
with minimal disruption of service. The system attempts to isolate each problem
to a single replaceable unit, whenever possible, by running automatic tests. In
private networked systems (Release 6.0 and later, Hybrid/PBX mode), many
problems are caused by programming errors rather than by malfunctioning
hardware. Errors that the system cannot automatically correct are usually
recorded in error logs. Most troubleshooting relies on checking the error logs
and interpreting them, using Table 2-6
.
Equipment
To perform maintenance, you need a maintenance terminal and some additional
tools, all of which are defined below.
Maintenance Terminal
Whether you perform onsite or remote maintenance, you need a maintenance
terminal:
â– For onsite maintenance, you can use either an MLX-20L system
programming console or a PC with System Programming and
Maintenance (SPM) software.
â– For remote maintenance, you must use a PC with SPM software.
