5.2 MDF/IDF Room Architecture
A MDF/IDF Room provides a controlled environment to house telecommunications equipment and
connecting hardware. It is also the demarcation point for all Facility, Backbone, Riser and horizontal
cabling. This room is not to be shared with Electrical service, Security, Paging, Video Surveillance or
alarm systems. This room should be located as close to the center of the building as possible.
The minimum dimensions for the MDF/IDF is 6’ x 8’ with a 9’ ceiling and a 36” door opening
outward. This room will support up to 80 City Personnel.
For buildings that house more than 80 people the minimum MDF/IDF size shall increase to 10’ x
10’with a 9’ ceiling and an outward swing 36” door. ITSD should be contacted during the design phase
to determine final room layout.
On buildings requiring a MDF and one or more IDF’S the distance between rooms should be limited to
180 meters.
Within this document there are “rules” and “guidelines”. The rules shall be followed precisely, while
the guidelines should be applied using common sense and improvising where necessary.
5.2.1 Plywood Backboard
One wall in any MDF/IDF will be completely covered with ¾” fire rated plywood with stamps
visible for inspection and if possible placed on a permanent wall and no more than 12” above
