Troubleshooting
3.1 Chapter Overview
This chapter describes how to troubleshoot your DXL5000
Digital Microwave System (DXL5000) Transmitter and Receiver.
3.2 Errors/Alarms
Errors detected during normal operation of the DXL5000 System
Transmitter or Receiver will cause the front panel MAJOR
ALARM, MINOR ALARM, or SCM STATUS LED indicators to
turn amber or red to alert you to investigate the problem. See
Figure 3-1.
Figure 3-1: Alarm Indicators- Typical
When flashing amber, the MAJOR ALARM LED indicates the
PA is off and the summary alarm relay has tripped; when amber,
a major alarm has been detected but no action has been taken.
When green, the MINOR ALARM LED indicates no alerts are
present; when amber, indicates an alert is present; and when
red, an alert is present and the alert relay has tripped.
When green, the SCM STATUS LED indicates no alarms are
present; when amber, a minor alarm is present; and when red,
as major SCM alarm is present.
Individual alarms are shown on the Alarms - Information tab
displayed on your PC or laptop when you are connected to the
rear panel MGMT connector, either directly or via the internet.
Note that alarms presented in this chapter reflect the factory
default alarm Severity and Type settings. The alarm Severity
level and Type settings may be changed by performing “Review
Transmitter Alarms” on page 2-16 to change the settings for an
alarm. See Figure 3-2 on page 3-2.
In Figure 3-2 on page 3-2, no alarms are present, the status for
each option indicates OK in green font, and the Summary
Alarm option button label indicates OK with a green
background. If major or minor faults are present, the option
status will indicate Fault in either red or amber font and the
Summary Alarm option button label will indicate Major or Minor
with a red or amber background, respectively.
If the Latch - On option is selected, you are alerted to the fact
that an error has occurred, even if the fault has been corrected.
When the On option is selected, the alarm must be
acknowledged using the Summary Alarm option button to clear
the alarm. If the Latch - Off option is selected, the alarm will
automatically reset when the fault is corrected.
To review a log of all alarms, select the Alarms - Log tab.
See Table 3-1 on page 3-3 for a list of Transmitter alarms and
what to do when they appear. See Table 3-2 on page 3-4 for a
list of Receiver alarms and what to do when they appear.
