Installation and Maintenance
The information in this section is for qualified service personnel only. Read
the
Read Me First: Safety and Electromagnetic Compatibility
document
included with your kit before using the power supply shuttle.
Caution
Many components within the 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 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-1075
chassis. The
NI PXIe-1075 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 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 ten 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 ten mounting
screws with a Phillips screwdriver.
