Serial CPU Board
Peripheral Slot Operation
Beyond the typical role as system slot card, the SC5-FESTIVAL 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# (Connector P1 Pin C3) will be disconnected
<
PWR_FAIL# (Connector P1 Pin F3) becomes GA1
<
PRST# (Connector P1 Pin H2) becomes RST# and may be disconnected
<
WAKE# (Connector P1 Pin I2) will be disconnected
<
SGPIO (Connector P1 Pins G3/H3/J3/K3) will be disconnected
One result of that is, that a SC5-FESTIVAL 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 SC5-FESTIVAL is not supported, no matter whether it is working as a system controller
or satellite board. But it is possible for the SC5-FESTIVAL 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 3.0
<
SATA 3.0
<
USB 2.0/3.0
<
Gigabit Ethernet
Except of PCI Express hot-plug is enabled on all interfaces by default. For PCI Express the UEFI/BIOS
(Build #138 or later) setup of the SC5-FESTIVAL provides settings to switch on or off the hot-plug
feature, for Fat Pipe or Standard peripheral slots on different menu places:
