Resetting the AC Mains Circuit Breaker

In the event that your VXI-1500 encounters an over-current condition,
the circuit breaker located on the rear panel will trip to prevent damage to
the mainframe. Complete the following steps to reset the circuit breaker:

1.  Turn the front panel power switch to the Off (0) position.

2.  Depress the circuit breaker to reset it.

3.  Turn the front panel power switch to the On (1) position.

If the circuit breaker trips again, complete the following steps:

1.  Disconnect the mainframe from the AC mains power source.

2.  Turn the front panel power switch to the Off position.

3.  Remove all VXIbus modules from the mainframe.

4.  Complete the test procedure described in the Connecting to AC

Mains Power and Testing Power Up section in Chapter 2,
Installation and Configuration.

5.  If any voltages are outside the acceptable limits, contact National

Instruments.

6.  If all voltages are within the acceptable limits, verify that the power

requirements of your VXIbus modules can be met by your
VXI-1500. Overloading the chassis can cause the breaker to trip.
Refer to Appendix A, Specifications.

7.  The over-current condition that caused your VXI-1500 circuit

breaker to trip may be due to a faulty VXIbus module. Refer to the
documentation that was supplied with your VXIbus modules for
troubleshooting your modules.

Troubleshooting the VXI-1500

Refer to Table 3-1 to troubleshoot the VXI-1500 mainframe. The table
lists possible causes why the power does not come on and gives
recommendations for correcting the problem.
