patch panel and wire manager.
The Data equipment can now follow with wire manager above and below each piece of
equipment.
A rack mounted UPS shall be installed in the bottom of the data cabinet.
Small standalone devices are not to be placed on the floor, or stacked on top of each other

5.4 Cable Management
This section outlines the rules for routing all cable and wire within all MDF/IDF rooms.
A. All cables originating on the front of a patch panel or device, or connecting within a rack or
between racks shall be routed through whatever rings, brackets, or Velcro straps are provided on either
side of the rack. If no such rings or brackets are present, they shall be added.
B. The cables shall be routed symmetrically. That is, cables originating on the right half of the cabinet
shall be routed through the rings or brackets on the right side of the cabinet, those originating on the
left half shall be routed on the left side of the rack.
C. Upon completing a circuit disconnect, the jumper/patch cord shall be removed to eliminate the
possibility of snagging and as a positive indication the port is unused. This does not apply at locations
with dedicated port assignments.
