3.2 Mounting limitations within a cabinet
The following mounting limitations within a cabinet exist for Series 8:
• The Power System pr24 VDC power to compatible assemblies through the header board on top of
one or more cabinets.
• The top connector of the topmost drop cable plugs into a connector on the header board. Use this cable to
connect to all the Series 8 IOTAs. These have three kinds of dimensions: six-inches (152 mm), nine inches
(229 mm) and 12 inches (305 mm).
• An extension cable is used to extend the I/O link to another cabinet side. It can plug into taps on a header
board, at the end of a header board, or at the bottom of a drop cable (although this is not normally done).
Extension cables are normally used to extend a header board to another cabinet side in a complex.
