!Card Cage and Midplane on page 21

!Chassis Versions on page 25

!Power Supplies on page 26

!Power Transition Modules on page 28

!Cooling and Fans on page 29

The chassis is a rack-mountable, 19-inch wide, 13 U high housing that contains the modules, power supplies and fans. The chassis accepts CompactPCI standard modules that conform to dimensions specified in IEEE Standard 1101.1-1998. The use of a midplane as the interconnecting device allows modules to be installed from both the front and rear of the chassis.

See Figure 4 on page 11 and Figure 6 on page 13 for illustrations of the front and rear of a fully populated chassis.
