SC6-TANGO • CompactPC® Serial • Intel® Atom™ E39xx Processor (APL-I SoC)
Peripheral Slot Operation
Beyond the typical role as system slot card, the SC6-TANGO is operable in periphery slots as well.
In this case it acts as a satellite system, linked to other (processor-) boards by its backplane
Ethernet connections. The other resources associated with the backplane like PCI Express, SATA
or USB are not usable in this situation.
Some of the following, system slot dedicated control signals get an altered function or will be
disconnected from the backplane:
<
PWRBTN#will be disconnected
<
PWR_FAIL# becomes GA1
<
PRST# becomes RST# and may be disconnected
<
WAKE# will be disconnected
<
SGPIO will be disconnected
One result of that is, that a SC6-TANGO plugged into a peripheral slot will not get a reset even if
the system controller forces the reset signal on the backplane to an active state.
Board Hot-Plug
Hot-plug of the SC6-TANGO is not supported, no matter whether it is working as a system
controller or satellite board. But it is possible for the SC6-TANGO to detect and handle hot-plug
events of periphery boards. This feature is supported on all interfaces fed to the CompactPCI Serial
backplane, i.e.
<
PCI Express 2.0
<
USB 2.0
<
Gigabit Ethernet
