document included with the kit.
Removal
The NI PXIe-1085 Series power supply is a replacement part for the NI PXIe-1085 Series
chassis. Before attempting to replace the power supply, verify that there is adequate clearance
behind the chassis. Disconnect the power cable from the power supply shuttle on the back of the
chassis. Identify the eight mounting screws for the chassis that attach the power supply shuttle
to the chassis. Refer to Figure 1-2,
Rear View of the NI PXIe-1085 Series Chassis
, for the screw
locations. Using a Phillips screwdriver, remove the screws. Pull on the two rear handles of the
power supply shuttle to remove it from the back of the chassis, as shown in Figure 3-1. About
halfway through removing the shuttle, the shuttle rail safety catches engage to prevent the shuttle
from falling out. Press down on the shuttle rail safety catches to remove the shuttle the rest of
the way, as shown in Figure 3-1.
After removing the shuttle from the chassis, you can access the modular power supply. To
remove the modular power supply, first loosen the four screws that retain it. Refer to Figure 3-1
for the screw locations. After loosening the screws, you can remove the modular power supply
by rotating the handle away from the fans and pulling upward when it is in the upright position,
as shown in Figure 3-2.
