VP 300 HARDWARE INSTALLATION

System physical installation begins by connecting the printer to the VP 300, applying power and observing
the VP 300 selftest.

Connect the VP 300 power cord to the dedicated power circuit and turn the cabinet
power switch to ON.
The LEDs on each circuit board are ON or OFF according to the following sequence
after powering up or reset:
1. Diagnostic Phase (red LED ON, green LED OFF)
After powering up or reset, each circuit board executes its diagnostic selftest. While
the selftest is being performed, the red LED is ON and the green LED is OFF. A
diagnostic selftest can take up to five minutes.
2. Software Download Phase (red LED ON, green LED ON)
If a circuit board's diagnostic selftest is successful, the green LED is turned ON. If
the green LED does not come on within five minutes after powering up or reset,
replace the circuit board.
3. Operational Phase (red LED OFF, green LED ON)
The downloaded operational software turns OFF the red LED, indicating that the
circuit board is operational.
4. Activity LED (yellow LED ON or OFF)
The yellow LED indicates activity. The meaning of the yellow LED is circuit board
dependent.
The AC and DC wiring is pre-wired to connectors that automatically engage when
the power supply is installed. There are no power supply adjustments. Use a digital
voltmeter to measure the system DC voltages at the voltage test points at the front
edge of the CPU board. Measure between Test Point 1, ground (use common probe
lead), and other test points to determine if voltages are in range (see Table 3-6). If
any voltage is out of range, replace the power supply.
