An equipment failure during the Burn -In Period is defined as a condition where a component stops functioning. A system failure is defined as a condition under which the system is unable to function as a whole or in significant part to provide the services as designated. While a single component failure may not constitute a system failure, chronic failure of that component or component type may be sufficient to be considered a system failure as determined by the Engineer. What constitutes a chronic failure shall be agreed upon in writing by the Contracto r and the Engineer prior to beginning the Burn - In. ITS electronic equipment which has repeated failures (repeated failures are defined as more than two in a thirty -day period) during the Burn -In Period shall be replaced by the Contractor at no cost to the Department. Field Test must be conducted for the new equipment and the Engineer’s acceptance shall be obtained for said testing. Upon satisfactory completion of t he testing, the Engineer will provide written authorization to commence with a thirty (30) day Burn -In Period for the new equipment. Final acceptance shall mean successful completion of Burn- In to the satisfaction of the Engineer. If any equipment or dev ice fails to complete the thirty (30) day Burn- In Period, the Burn -In Period shall be suspended and time charges resumed. The Burn -In Period will not be restarted except when the following has been met: • Repairs to the malfunctioning equipment/device have been satisfactory completed; and, • The repaired equipment/device is to be re -tested and proven to be properly functioning. Only upon the Engineer’s acceptance of the repaired equipment/device, will the Contractor be allowed to resume the Burn -In Period. General communication outage or failure due to hardware is considered a system failure in any case. Communication failure due to a minor component may not be a system failure. Specifically exempted as system failures are failures caused by accident, natur al disasters, or other external forces. The Engineer will advise the Contractor in writing when it considers that a system failure has occurred or a chronic failure exists. Each system failure during this Burn -In Period shall require restarting the clock plus an additional two (2) calendar days of successful operation prior to being eligible for final acceptance (i.e., if there are two system failures during the initial 30 day period, the period would be increased by 4 days). Successful completion of the Burn- In Period shall occur at the end of thirty (30) complete calendar days of operation without a system failure ascribable to hardware, software, or communications components. The Contractor shall generate Test Result Documentation for the Burn -In which shall include at a minimum: • Documentation for any ITS electronic equipment failures, system failures or communications failures; • Document corrective actions taken by the Contractor for equipment repairs; • Any re -test documentation for the repaired or repl acement equipment; • All manufacturers’ ITS electronic equipment protocol control software; and, • All manufacturers’ configuration and diagnostic software along with licenses transferred to the Department.
