Special Procedures
This section contains information on special procedures.
Health Check
The Health Check function provides a method to periodically determine the operational state of an SNC
4000 and its attached interfaces and devices.
Manual Health Check
Health Check is performed manually from the service terminal only if the SNC 4000 is in normal mode.
See
Perform Health Check
on page 44, for instructions.
Event Log Dump
The events that have been logged in the SNC 4000’s Event Log can be displayed on the service terminal
or viewed from the ADIC Management Console. For more information, see the
ADIC Management Console
User’s Guide
.
This information may be useful because you can see the normal events and any abnormal events that may
lead you to the source of an internal or external failure.
Each entry contains a sequence number, day, and time-stamp, the event code, event source (interface
name or system process), an index, and a description of the event.
If the Real Time Clock has been set, the time-stamp will be real time. Otherwise, the time stamp will be
relative to the boot-time.
The Event Log holds more than 2000 events. When the log becomes full, the oldest events are overwritten
by the most recent events.
You can choose to view only those events logged since the SNC 4000 was last booted or you can view a
longer list of events that have accumulated from previous boots.
You can choose to view events by severity level. Selecting
Warning
will display
Warning
and

events. Selecting
Information
will display

,
Warning
and
Notice
events.
See the
