NI PXI-1042 Series
Power Supply Shuttle

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

Introduction

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

Unpacking

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.
