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 PXI-1042 Series 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 an NI PXI-1042 Series 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 PXI-1042 Series
chassis. The NI PXI-1042 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 PXI-1042 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. Set the power switch on the front
panel to the Off (nonrecessed) position and disconnect the power cable
from the power supply shuttle on the back of the chassis. Identify the eight
captive mounting screws that attach the power supply shuttle to the chassis.
Refer to Figure 1 for the mounting screw locations. Using a Phillips
screwdriver, loosen the captive 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. Tighten the eight captive mounting
screws with a Phillips screwdriver.
