PMAC PCI Lite Hardware Reference Manual
Hardware Reference Summary 29
J31 – Optional Universal Serial Bus Port (JUSB Port)
This optional port allows communication with PMAC through a standard USB connection.
JS1 – Expansion Ports (JS1 Port)
This port is used only when connecting to optional PMAC accessory boards.
TB1 – Power Supply Terminal Block (JPWR Connector)
This terminal block may be used as an alternative power supply connector if PMAC is not installed in a
PCI-bus.
LED Indicators
D20 and D20A: When these green LEDs are lit, they indicate that power is applied to the +5V input.
D21 and D21A: When these red LEDs are lit, they indicate that the watchdog timer has tripped and shut
down the PMAC.
D15: The PMAC has an interlock circuit that drops out the ±15V supplies to the analog outputs through a
fail-safe relay if any supply on PMAC is lost. In this case, the green LED D15 will be off.
Fuse
The 5V output through the J5 JOPTO connector is protected by F1, which is a 2-Amp fuse of the
following type:
