Hungary Telecom IPTV Data Center Construction Project - Site Survey

After confirming the cabinet layout diagram, equipment connection diagram and power distribution table of the IPTV headend equipment site with the Construction Department of Magyar Telekom, it is necessary to conduct an on-site survey in the equipment room together with the corresponding personnel of the Construction Department of Magyar Telekom. The main purpose of the on-site equipment room survey is to comprehensively evaluate the physical environment, electrical system, safety facilities and other conditions of the equipment room, so as to ensure that the equipment room can meet the requirements for normal installation and operation of the IPTV headend equipment.

There is a corresponding survey report template for the survey of the IPTV headend equipment room, which mainly includes:

• Equipment room name and location

• Temperature and humidity of the equipment room

• Cabling mode of the equipment room: overhead cabling, underfloor cabling, hybrid cabling

• Height of anti-static floor

• Type of cable tray: single-layer, double-layer, other types

• Height and width of cable tray

• Cable routing mode of cable tray: layered routing, same-layer routing

• Cabling convention: communication cables on the upper layer and power cables on the lower layer; communication cables on the right and power cables on the left

• Installation positions of newly added cabinets and equipment: marked on the equipment room floor plan, with row and column numbers

• Type, size and quantity of newly added cabinets

• Whether there are obstacles under the anti-static floor at the installation positions of newly added cabinets: obstacles need to be cleared in advance; if they cannot be removed, the installation positions shall be changed

• Type, specification and quantity of matching bases for newly added cabinets

• Whether new cable trays are required: Yes / No

• Specification, quantity and installation positions of newly added cable trays: marked on the equipment room floor plan, with row, column and height information

• Whether new ODF racks are required: Yes / No

• Specification, quantity and installation positions of newly added ODF racks: marked on the equipment room floor plan, with row and column numbers

• Locations of existing ODF racks in the equipment room, positions of interconnected ODF terminals and types of ODF terminals: marked on the equipment room floor plan, with row, column and quantity information

• Type, quantity and length of interconnected pigtails

• Locations of existing -48V power supplies in the equipment room, positions of interconnected power terminals and types of interconnected power terminals: marked on the equipment room floor plan, with row, column and quantity information

• Specification, quantity and length of -48V power cables from existing -48V power supplies in the equipment room to the newly built PDF cabinet

• Specification, quantity and length of -48V power cables from newly built equipment cabinets to the newly built PDF cabinet

• Locations of existing equipment requiring direct interconnection in the equipment room: marked on the equipment room floor plan, with row and column numbers

• Type of connectors, type, quantity and length of interconnection cables for existing equipment requiring direct interconnection in the equipment room

All other survey items in this on-site survey went smoothly, except that the -48V power supply was 25 meters away from the newly built PDF cabinet matching the IPTV headend equipment, far exceeding the conventional distance of 10 meters.

There are 9 equipment cabinets in total for this IPTV headend equipment site, with a designed maximum power consumption of 3000W per cabinet and a total designed maximum power consumption of 27000W. The designed maximum current is 27000W / 48V = 562.5A. Considering the voltage drop over the 25-meter distance, it was determined after communication with the customer that two 120mm² -48V power cables shall be used as the input power cables for the newly built PDF cabinet to ensure power supply safety.

After being reviewed and approved by both parties, the survey report was uploaded to the system to guide equipment production and stock preparation.
