Site or Satellite Closets
When determining the site or satellite closets, use the following information as a guide.
Indicate the locations on the floor plan.
a.
b.
c.
d.
Keep the number of locations to a minimum.
To minimize the station wiring distances, centrally locate the site or satellite
closets among the information outlets.
Site or satellite closets should be easily accessible and contain sufficient ac power
outlets. Terminals equipped with adjuncts that require power can be remotely
powered from a site or satellite location as well as from the main equipment room
or at information outlets. The distance between the power supply and the terminal
cannot exceed 250 feet (76.2 m) using 24-gauge wire.
Locks should be provided for the site or satellite closet to prevent tampering.
Cabling Facilities
The method of riser cable distribution between the main equipment room and the site or
satellite closets is usually determined by the type of cabling facilities (riser closets, conduit
size, cabling shafts, etc.) placed during construction of the building (Figure 1-5).
a.
The preferred arrangement is to have individual cables supply each site or satellite
closet.
b.
A second method is to have one or two large cables supply all the site or satellite
closets. This method requires smaller cables to be installed between the main riser
cable and the site or satellite closet. These smaller cables are spliced into the main
cable.
Determine the type of cabling required and mark the type and routing on the blueprint or
floor plan. Also indicate any additional cabling facilities required for riser and terminal
cabling.
