NI PXI-1042 SeriesPower Supply Shuttle

The NI PXI-1042 Series power supply shuttle is a replacement part for the

NIPXI-1042 Series chassis.

To minimize downtime caused by a power-supply failure, the

NIP XI-1042 Series chassis has a modular power supply shuttle. This

power supply shuttle includes the chassis power supply, cooling fans, and

fan-control circuitry. Key features of the power supply shuttle include:

• Universal AC input with automatic voltage and frequency ranging

• Over-current protection via push-reset circuit breaker

• Remote power monitoring and inhibit via a rear-panel connector

• Temperature-sensing module that can adjust fan speed based on

air-intake temperature to minimize audible noise

• Circuitry to control a front-panel LED that indicates power supply

failure

Carefully inspect the shipping container and the power supply shuttle for

damage. Check for visible damage to the metal work. Check to make sure

all handles, hardware, and switches are undamaged. Visually inspect the

inside of the shuttle for any possible damage, debris, or detached

components. If damage appears to have been caused during shipment, file

a claim with the carrier. Retain the packing material for possible inspection

and/or reshipment.
