Key
PPC/CPCI-690
The only key available at the front panel is the mechanical reset key.
If the board is installed into a peripheral slot of a standard CompactPCI
system or a node slot of a PSB backplane using the CompactPCI bus, the re-
set key instantaneously affects the board by generating a main reset when
enabled and toggled. If the board is installed into a system slot, the main re-
set additionally generates a CompactPCI reset, i.e. a reset of the whole sys-
tem.
If a board is installed into a PSB backplane that does not use the Compact-
PCI bus, pressing the reset key results in a board reset.
When the reset key is pressed, all on-board I/O devices and the CPU are re-
set. Reset is held active until the key is released.
For information on how to disable the key, see Table 7 "Switch Settings"
page 2-14. For information on performing a reset via PowerBoot, refer to
"Reset" page 4-47.
