Chapter 2 Installation and Configuration
Connecting Safety Ground
Warning T h e PXI-101 1 chassis is designed with a three-position NEMA 15-5 style plug
that connects the ground line to the chassis ground. To minimize shock hazard, make sure
your electrical power outlet has an appropriate earth safety ground that is connected
whenever you power on the chassis.
I f your power outlet does not have an appropriate ground connection, you must connect the
premise safety ground to the chassis grounding screw located on the rear panel. Refer to
Figure 1-2,
Rear View of the PXI-1011 Chassis,
for a diagram locating 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 toothed
grounding lug. The wire must have green insulation with a yellow stripe or must be
non-insulated (bare).
2. A t t a c h the opposite end of the wire to permanent earth ground using toothed washers
or a toothed lug.
Installation
Follow these steps to install the PXI-1011 chassis:
1. P l a c e the PXI chassis on a sturdy, level surface. Leave at least 10 cm
(4 in.) of space behind the chassis for adequate air circulation.
2. T u r n off the system power switch.
3. I n s e r t the female end of your power cable into the power-entry module.
4. I n s e r t the male end of your power cable into the wall outlet.
5. I n s t a l l the SCXI and PXI modules into the chassis (see the appropriate
sections later in this chapter).
6. I n s t a l l any front and rear filler panels (see the appropriate sections later
in this chapter).
7. T u r n on the system power switch.
The system power indicator LED should be lit now, which indicates
that system power is available to both the PXI and SCXI subsystems.
The PXI subsystem remains powered as long as the system power is
on. The SCXI subsystem power, however, can be controlled using the
SCXI subsystem power switch on the rear panel.
8. I f the SCXI subsystem power indicator LED is lit, then the SCXI
subsystem power is on. If not, turn the SCXI subsystem power switch
on the rear panel to the On position. The SCXI subsystem power
switch can be used to turn the SCXI subsystem on and off only when
the system power is on.
