Front Panel Handle Microswitch Header P-FPH

The jumper P-FPH is used for attachment of an external SPDT switch. By default, P-FPH is connected
across a short cable harness to a microswitch, which is integrated into the SC2-PRESTO front panel
handle (ejector lever). The switch performs a power button event (e.g. system shutdown) by short-
circuiting the pins 1 and 3 of P-FPH when activated (hold unlock button of front panel handle
depressed momentarily).

PLD Programming Header P-ISP

The SC2-PRESTO is provided with a powerful PLD (in-System Programmable Logic Device) which
replaces legacy glue logic. The programming header P-ISP is not stuffed (in use for manufacturing
only). Its footprint is situated at the bottom side of the board.
