3Com® VCX V7111 VoIP Gateway User Guide 347CHAPTER 13: DIAGNOSTICSSeveral diagnostic tools are provided, enabling you to identify correct functioning of theV7111 gateway, or an error condition with a probable cause and a solution or workaround. Front and rear-panel LEDs on the V7111 gateway. The V7111 1x PORT front-panelLEDs are described in Table 3. The V7111 24 PORT front-panel LEDs are described inTable 6, the rear-panel LEDs are described in Table 8. Self-Testing on hardware initialization (see Self-Testing). Error / notification messages using the following interfaces: Syslog: Log messages can be viewed using an external Syslog server, see V7111Line Testing, or on the Message Log screen in the Embedded Web Server, seeActivating the Internal Syslog Viewer. Note that the Message Log screen is notrecommended for prolong debugging. RS-232 terminal: For information on establishing a serial communications link withthe V7111 gateway, see Establishing a Serial Communications Link with the V7111.Self-TestingThe V7111 gateway features two self-testing modes used to identify faulty hardwarecomponents: Rapid: The Rapid test is performed every time the V7111 gateway starts up. It isexecuted each time the V7111 gateway completes its initialization process. This is ashort test phase in which the only error detected and reported is failure in initializinghardware components. If an error is detected, an error message is sent to the Syslog. Detailed: Used in addition to the Rapid and Enhanced test modes. The test is performedon startup, when initialization of the V7111 gateway is completed and if the parameterEnableDiagnostics is set to 1 or 2. In this mode, the V7111 gateway tests its DSPs, RAMand flash memory. When EnableDiagnostics is set to 1, flash is tested thoroughly, whenEnableDiagnostics is set to 2, flash is only partially tested. While the Detailed test isrunning, 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 parameterEnableDiagnostics to 0 and reset the V7111 gateway.
