NI PXIe-1065 Power Supply
Shuttle
The NI PXIe-1065 power supply shuttle is a replacement part for the
NI PXIe-1065 chassis.
Caution This power supply is not compatible with any other National Instruments chassis.
Introduction
To minimize downtime caused by a power-supply failure, the
NI PXIe-1065 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.

Installation and Maintenance
The information in this section is for qualified service personnel only. Read
the Read Me First: Safety and Radio-Frequency Interference document
included with your kit before using the power supply shuttle.
Caution Many components within the NI PXIe-1065 chassis under repair are susceptible
to static discharge damage. Service the chassis only in a static-free environment. Observe
standard handling precautions for static-sensitive devices while servicing the chassis.
Always wear a grounded wrist strap, or equivalent, while servicing the chassis.
Caution Always disconnect the AC power cable before cleaning or servicing the chassis.
Caution Never connect the AC power cable to the power supply shuttle until you install it
in a NI PXIe-1065 chassis. Do not use, test, or configure the power supply shuttle outside
of a chassis.
The power supply shuttle is a replacement part for the NI PXIe-1065
chassis. The NI PXIe-1065 User Manual contains all of the most up-to-date
chassis service procedures, including removal and replacement of power
supply shuttles. The chassis includes a hardcopy of the NI PXIe-1065 User
Manual; additionally, you can download a softcopy from ni.com/
support.
Removal
Before attempting to replace the power supply shuttle, verify that there
is adequate clearance behind the chassis. With the chassis powered off,
disconnect the power cable from the power supply shuttle on the back of
the chassis. Identify the eight mounting screws that attach the power supply
shuttle to the chassis. Refer to Figure 1 for the mounting screw locations.
Using a Phillips screwdriver, remove the mounting screws. Pull on the
two rear handles of the power supply shuttle to remove it from the back of
the chassis.
Installation
Ensure that there is no visible damage to the new power supply shuttle.
Verify that the housing and connector on the new power supply shuttle
have no foreign material inside. Remove the protective cap on the
PXI_CLK10 connector. Install the new power supply shuttle into the
opening on the rear of the chassis. Install and tighten the eight mounting
screws with a Phillips screwdriver.

Configuration
The fan-speed selector switch is on the rear panel of the power supply
shuttle. Refer to Figure 1 to locate the fan-speed selector. Select HIGH for
maximum cooling performance (recommended) or AUTO for quieter
operation. When set to AUTO, air-intake temperature determines the fan
speed.
Connecting Safety Ground
Caution The power supply shuttle is designed with a three-position NEMA 5-15
(IEC 60320) jack that connects the ground line to the chassis ground. To minimize
shock hazard, make sure the electrical power outlet you use to power the chassis has
an appropriate earth safety ground.
If your power outlet does not have an appropriate ground connection, you
must connect the premise safety ground to the chassis grounding screw.
Refer to Figure 1 to locate the chassis grounding screw. To connect the
safety ground, complete the following steps:
1. Connect a 16 AWG (1.3 mm) wire to the chassis grounding screw
using a grounding lug. The wire must have green insulation with a
yellow stripe or must be noninsulated (bare).
2. Attach the opposite end of the wire to permanent earth ground using
toothed washers or a toothed lug.
