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.
