NI PXI-1045 Power Supply Shuttle

This document explains the installation and maintenance of the 

NI PXI-1045 power supply shuttle. The NI PXI-1045 power supply shuttle 

is a replacement part for the PXI-1045 chassis.

Introduction

To minimize downtime caused by a power supply failure, the PXI-1045 

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 through push-reset circuit breaker

•

Remote voltage monitoring and inhibit through 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.
