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 SC3-LARGO 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).
