Configure Rapid Spanning Tree Protocol (RSTP) to prevent bridging loops and provide redundant paths. 7. Disable any ports not in use. 8. Testing. Develop and submit an Acceptance Test Plan (ATP) to the Engineer for approval as detailed in the 12SP-826I - System Integration and Testing. 9. Warranty. Provide a MFES with a standard manufacturer’s warranty, transferable to MDOT. The MFES must carry a warranty (parts, software, and labor) of 5 years from the date of shipment with at least 4 years of warranty remaining at the start of burn-in. Furnish warranty and other applicable documents from the manufacturer, and a copy of the invoice showing the date of shipment, to the Engineer prior to final written acceptance. 10. Remove and Salvage. If MFES remove and salvage is specified in the contract, the following procedures apply: A. Do not damage the ITS cabinet or associated equipment; B. Remove the MFES, mounting hardware, power supply, and power cabling associated with the MFES. Disconnect all communication cables from the MFES and leave them in place unless otherwise directed by the Engineer; C.

Salvage the MFES, including mounting hardware, power supply, surge protectors (if any) and cabling, as directed by the Engineer. Store the salvaged equipment at a location free of moisture, and rodent/insect intrusion. If the MFES is to be reinstalled it must be stored until then, otherwise notify the Engineer once the equipment has been salvaged for pickup to be arranged. 11. Install Salvaged. If a salvaged MFES is to be installed at a location specified in the contract, follow the procedures detailed in sections c.1 through c.8 in this special provision and the MFES test requirements in the 12SP-826I - System Integration and Testing. d.
