The wiring closets at Mount Holyoke will include all of the following:
While room for all of these system should be considered, there may be a need for additional wiring closets in a building if the Cat 5 specification is exceeded. The specification calls for data ports to be no more than 100 meters from the patch panel in the wiring closet to the end station (computer). Because of this we require that the length of the wire run from the patch panel in the wire closet to the data drop, be no more than 85 meters. This allows us to use a longer patch cable in an office if necessary.
The walls of the wire closet should be fully lined with plywood and most of the components in it should be wall mounted on that plywood. The mounting plywood should be from two feet off the floor to seven feet off the floor. All Data components should be placed in a 19 inch rack and not on the wall.
|Our present color code is as follows:|
|Data = Gray||Phone = Blue||HVAC = Green||Door Access = Yellow|
|This is an view of a wiring closet. Telephone and access control equipment are on the left, video cables are on the far left, a fiber optic panel is straight ahead, and a piece of the data rack is on the right.|
|Here are the front and back views of a data rack. There is no UPS for this equipment, but a UPS could be placed next to the rack. This rack holds 7x24 data ports. Normally we would recommend limiting a rack to 6x24 data ports and installing a second rack if there are more.|
