Chassis

This section discusses the following characteristics of the G10 CMTS chassis components:

! Physical Characteristics on page 20

! 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.
