106 <br /> Computer Room Physical and Security Requirements <br /> Refer to Departmental Manual (DM 3510-001) "Physical Security Standards for Information Technology (IT) <br /> Restricted Space" and the "CEC Space and ADP Room Guidelines". <br /> Dedicated Electrical Circuits and Outlets for ADP Equipment <br /> 1. ADP Room and Demarcation Point Circuits: Provide and install dedicated electrical circuits with isolated <br /> grounds in the computer room. Dedicated circuits must be 110 volt, 20-amp standard three-prong circuits <br /> with true earth ground terminated into orange or other uniquely marked (computer use only) duplex <br /> outlets. Provide and install duplex outlets for each dedicated electrical circuit in the computer room and any <br /> distribution closets. One dedicated outlet for the explicit use of USDA/OCIO/CEC should also be provided at <br /> the demarcation point.The main electrical panel for the computer/voice equipment will be properly <br /> grounded. <br /> 2. General Office Space Circuits: Provide enough dedicated electrical circuits and multiple outlets at designated <br /> locations throughout the service center to accommodate workstations, copiers, etc. <br /> 3. Electrical Requirements for Uninterruptible Power Supply(UPS) Circuit: All CEC network equipment in the <br /> computer room is required to be connected to a UPS. <br /> 4. Number and Type of Circuits:There will be a minimum of one 120 volt, 30-amp minimum with true ground, <br /> terminated into a twisting-lock NEMA L5-30R receptacle. Each dedicated circuit must have insulated, <br /> isolated earth ground; conduit ground is not acceptable. <br /> 5. Location of the UPS receptacle:The receptacle will be located within a maximum of 4.5 feet from the back <br /> of the computer room wiring cabinet. <br /> Plywood Wall Mounting <br /> One sheet of% inch 4 x 4-foot plywood or equivalent open space on an existing backboard, shall be vertically <br /> mounted on the wall at the internal demarcation point within 3-feet of an electrical outlet.The backboard <br /> should be attached to the wall using correct mounting hardware and procedures. If the wall is sheet-rocked, <br /> attach the backboard to the studs. If the wall is concrete, attach the backboard using anchors.The backboard <br /> should be painted with fire retardant paint the same color as the interior walls of the building. <br /> Demarcation Point (D-Mark) <br /> 1. When possible, all telecommunication company demarcation points should be internal to the building.The <br /> lessor is responsible for ensuring there is a route available for any extended demark need from the building <br /> demark to the USDA ADP room. Any demarcation extension should be coordinated with TSD and the <br /> sponsoring agency to ensure the work is properly sourced and funded. <br /> 2. A 4-inch conduit with pull cable for the explicit use of USDA should be installed from the demarcation point <br /> to the USDA ADP (Computer) Room. <br /> 3. For any analog Plain Old Telephone Service (POTS) lines delivered to the office, extend them from the <br /> demark to the extended demark at the computer room and utilize 6P4C surface mount jacks to <br /> accommodate RJ11 cables, such as the following: <br /> Page 2 Lessor Gov't FPAC V11.13.202020 <br />
