INTRODUCTION

PURPOSE OF THIS REPORT

This document is intended to be used by those designing, building, and equipping new buildings, as well as renovations associated with existing buildings and classrooms. This document includes design guidelines for:

A. Telecommunications connections to each campus.

B. Critical technology space needs, including Main Distribution Frames and Technology Closets.

C. An IP network standard for both wired and wireless networks in each building.

D. Office of Technology Services Structured Cabling Standard.

This report presents pragmatic, step-by-step technology design elements expressed as Technology Standards. Bond Program architects and engineers should carefully review these standards as designs are developed, ensuring these minimum guidelines are included in the program and budget for each building.

TECHNOLOGY SPACES

1.1 Main Distribution Frame (MDF)

Larger buildings that are designated as an IT distribution point (this will be determined by IT per project) and new campuses will require a separate Main Distribution Frame to house local servers, controllers for digital signage, and telecommunications equipment. The construction must conform to the current ANSI/TIA 569 Standard for Commercial Building Telecommunications Pathways and Spaces.

A. The MDF should be at least 250 sq. ft. in size, as geometrically square as possible, and located toward the center or core of the building structure.

B. The room should be placed on the ground floor whenever possible due to equipment access and floor loading considerations. Avoid placing the Main Distribution Frame next to outside walls, elevator shafts, and/or internal fixed building walls.
