13 Diagnostics
Several diagnostic tools are provided, enabling you to identify correct functioning of the
MediaPack, or an error condition with a probable cause and a solution or workaround.
• Front and rear panel indicator LEDs on the MediaPack. The location and functionality of the
MP-1xx front panel LEDs is shown in Section
2.1.1.2 on page 24. The location and
functionality of the MP-1xx rear panel LEDs is shown in Sections 2.1.2 and 25. The location
and functionality of the MP-11x front panel LEDs is shown in Table 2-7 on page 27.
• Self-Testing on hardware initialization, refer to Section
13.1 below.
• Error / notification messages via the following interfaces:
¾ Syslog - Log messages can be viewed using an external Syslog server, refer to Section
13.2 on page 222, or on the ‘Message Log’ screen in the Embedded Web Server, refer
to Section 5.7.3 on page 153. Note that the ‘Message Log’ screen is not recommended
for prolong debugging.
¾ RS-232 terminal - For information on establishing a serial communications link with the
MediaPack, refer to Section 10.2 on page 201.
13.1 Self-Testing
The MediaPack features two self-testing modes: rapid and detailed.
• Rapid Self-Test Mode - Rapid self-test mode is run each time the media gateway completes
the initialization process. This is a short test phase in which the only errors detected and
reported are failure in initializing hardware components. All Status and Error reports in this
self-test phase are reported through the Syslog, as well as indicated by the LED Status
Indicators.
• Detailed Self-Test Mode - Detailed self-test mode is run when initialization of the gateway is
completed and if the configuration parameter EnableDiagnostics is set to 1 or 2 (when set to
1, flash is tested thoroughly, when set to 2, flash is partially tested). In this mode, the media
gateway tests all hardware components (memory, DSP, etc.), outputs the status of the test
results (to Syslog), and ends the test.
The gateway doesn’t process calls while in Detailed self-test mode. When you are finished
running the detailed test, you must disable it (EnableDiagnostics = 0) and reset the gateway.
