Chapter 6 Troubleshooting the VG248 Troubleshooting Software Errors Table 6-1 Hardware Errors and Warnings Explanation (continued) System SCCP SLIC SLIC Error Failed to update real-time clock EDSP failure warning received over-temperature warning received Explanation The on-board real-time clock in the VG248 has failed to set the time from Cisco CallManager. A transient fault has been detected in the SLICs (the hardware that drives the analog telephony interfaces). Action Contact a Cisco technical representative for assistance. If these messages persist, contact a Cisco technical representative for assistance. Troubleshooting Software Errors The VG248 displays informational messages and errors on-screen or in the event log (see the "Working with the Event Log" section on page 6-22 for details on accessing the event log), which indicate potential software problems, such as misconfiguration, time-outs, unreachable servers, and so on. The following sections provide details about resolving these errors: • Resolving Network and System Errors, page 6-5 • Resolving Analog Errors, page 6-10 • Resolving Cisco CallManager Errors, page 6-11 Resolving Network and System Errors Table 6-2 describes errors and warnings that might appear on the VG248 either on-screen or in the event log (see the "Working with the Event Log" section on page 6-22 for details on accessing the event log), which are caused by a misconfiguration or miscommunication with the network or system settings. Use this information to resolve these errors. OL-1209-02 Cisco VG248 Analog Phone Gateway Software Configuration Guide 6-5
