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
PC7-FESTIVAL 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).
