System Controller Frame Module Slots
The Encore System Controller Frame has two slots for System Controller
(SCB) modules, and two slots for power supply modules (see
Figure 3 on
page 25).
Note Modules must be completely seated to operate properly. The fan and LEDs
will come on before the Controller module is fully seated. See the Mainte
-
nance Section (To Insert System Controller Modules on page 73) for instruc-
tions on removing and inserting the Controller module.
System Controller (SCB) Module
The SCB has two standard components, the System Controller module
motherboard and a Control Processor sub-module. Additional SIO and
GSC mezzanines are available, which mount one above the other. The mez
-
zanine mounting order does not affect operation. However, because the
SIO mezzanine has user adjustments, if both are installed it is recom
-
mended to install the SIO mezzanine above the GSC mezzanine
(
Figure 16).
