There are four categories required for room selection. They are given below:

Location

1. Room Obstructions - The area must be free of obstructions that may interfere with the installation of the cable and infrastructure needed to manage the cabling and equipment.
2. Cable Chases - The room must be within 10 of an existing telecommunications closet or major network cabling chase or have an area designated for chase space.
3. Ceiling Obstructions - The rooms ceiling or the ceiling around the room cannot be obstructed by air conditioning ducts or electrical conduit unless such space has been determined to be allowable.
4. Cable Distance - The furthest telecommunications outlet must be within 285ft of the designated telecommunications room area.
5. Electrical Devices/Panels - Electrical devices must not be located within or near the selected telecommunications area unless it is at least 10 way from any cable paths or racks.
6. Service Closets - The designated telecommunications area must be near service closets and chases so the cost of extending those services is not excessive.

Size

1. Acceptable Size - Adequate space must be present in the room for racks, UPS power, air-flow, and hardware installation space.
2. Size Determination - The telecommunications space shall be sized according to the number of outlets serviced by the designated location and the type of networking hardware required including UPS.
3. Additional Space - Extra space shall be designated for special services such as security and other planned devices.
4. Distance Around Equipment - A minimum or three feet is required around telecommunications equipment and racks.

 Environment

1. Lighting - adequate lighting is required around racks and punch down boards.
2. Air conditioning - The room should have a controlled air environment which does not allow the room to exhibit temperature extremes.
3. Airflow - Constant 24 hour air-flow is required in the room so the temperature values are not exceeded in the equipment.
4. Security - The area designated for a telecommunications room must be able to be secured either with a lock or a card reader system.

 Electrical Power

1. Power Circuits- Dedicated power is required for both UPS and non-UPS equipment. Separate circuits shall be installed for both types.
2. Power Locations - The UPS power circuit must be within six feet of the designated location of the UPS system within the room.
