1.7 RAN Chassis and Electronic Modules
The RAN chassis, shown in Figure 6 , is a standard Compact PCI (cPCI) shelf capable of
housing 21 industry standard cPCI circuit cards (called “electronic modules” in this manual).
The backplane supports the basic cPCI functions and it has been extended to allow the routing
of DIF
TM
, reference clocks and I2C signals between I2C modules. The RAN chassis also houses
cooling fans within the Fan Access Panel on the top of the chassis. Table 3 identifies the
electronic modules using the callout reference numbers from Figure 6 .
