Fire Protection. Fire Protection guidelines for unoccupied
telecommunications spaces will be in accordance with UFC 3-600-01, Design:
Fire Protection and Engineering for Facilities. Based on the NMCI Contract
Administrators, these spaces are network distribution areas, are not considered
"critical facilities", and are not required to comply with NFPA 75, Standard for
Protection of Information Technology Equipment or NFPA 76, Recommended
Practice for Fire Protection of Telecommunications Facilities. However, these
spaces must be designed and constructed for a 1-hour fire rating.
Although regional server farms are not covered by this UFC (UFC
3-580-10,) they are the first level of infrastructure that are considered critical
facilities by the NMCI Contractor (in concurrence with the NMCI Contract
administrators), and therefore only the regional server farms and NOCs are
required to comply with NFPA 75 Standard for Protection of Information
Technology Equipment.
