FX II Hardware Introduction 
GCA39-824 Rev 2, Issue 4/02  Page 20  Printed in the USA 
FX II 18 Slot System (Fiber Expansion) 
This configuration is similar to the 18 slot SCSI expansion. The difference is the expansion kits 
used listed in bold below. Fiber Expansion allows for extended distance between the Main 
Cabinet (A) and Expansion Cabinets B and D. Use this configuration when installing the 
expansion cabinets up to a mile away from the main cabinet in a campus environment or high-
rise building. 
There are 18 universal slots in a 3 cabinet configuration. 
All board slots are 32 bit and accept either line or station boards. Using T1 or E1 line boards, as 
well as the IMIST Module, can maximize the 32 bit slot capabilities.
