14 Diagnostics

Several diagnostic tools are provided, enabling you to identify correct functioning of the

Mediant 1000, or an error condition with a probable cause and a solution or workaround.

 Front and rear-panel LEDs on the Mediant 1000. The location and functionality of the

Mediant 1000 front panel LEDs is shown in Section 2.1.5 on page 31.

 Self-Testing on hardware initialization (refer to Section 14.1 below).

 Line testing (refer to Section 14.2 on page 342).

 Error / notification messages via the following interfaces:

• Syslog: Log messages can be viewed using an external Syslog server (refer to

Section 14.3 on page 342), or in the ‘Message Log’ screen in the Embedded Web

Server (refer to Section 5.7.2 on page 182). Note that the ‘Message Log’ screen

is not recommended for prolong debugging.

• RS-232 terminal (for establishing a serial communications link with the Mediant

1000, refer to Section 11.2 on page 297).

14.1 Self-Testing

The Mediant 1000 features two self-testing modes used to identify faulty hardware

components:

 Rapid: The Rapid test is performed every time the Mediant 1000 starts up. It is

executed each time the Mediant 1000 completes its initialization process. This is a

short test phase in which the only error detected and reported is failure in initializing

hardware components. If an error is detected, an error message is sent to the Syslog.

 Detailed: Used in addition to the Rapid test mode. The test is performed on startup,

when initialization of the Mediant 1000 is completed and if the parameter

EnableDiagnostics is set to 1 or 2. In this mode, the Mediant 1000 tests its DSPs,

RAM and flash memory. When EnableDiagnostics is set to 1, flash is tested

thoroughly, when EnableDiagnostics is set to 2, flash is only partially tested. While the

Detailed test is running, the Ready and Fail LEDs are lit.

If an error is detected, an error message is sent to the Syslog.

Warning: To continue regular operation, the Detailed test must be disabled. Set

the parameter EnableDiagnostics to 0, and then reset the Mediant 1000.
