power switch connector (J4)
The PCM-9550F/FM/L can support an advanced soft power
switch function, if an ATX power supply is used. To enable the
soft power switch function:
1. Get the specially designed ATX-to-EBX power cable
(PCM-9550F/FM/L optional item, part no. 1703200100)
2. Connect the 3-pin plug of the cable to CN5 (ATX feature
connector).
3. Connect the power on/off button to J4. (A momentary button
switch should be used.)
Important: Make sure that the ATX power supply can take at
least a 10 mA load on the 5 V standby lead
(5VSB). If not, you may have difficulty powering
on your system.
