Common Questions
My chassis worked fine until I inadvertently removed and reinserted a
module while the chassis was on. Now my chassis does not power on.
What can I do?
SCXI modules are not hot swapable, so you may have blown a fuse. Refer
to Chapter 2,
Configuring and Installing the SCXI Chassis
, for information
on fuse replacement. If replacing the fuse does not correct the problem, you
may have damaged the digital bus circuitry or the SCXI module. Please
contact NI Technical Support at
ni.com/support
for assistance.
My chassis power is on, my modules are configured for multiplexed
mode, and I am not getting good data. All the channels read the same
voltage even though I know I am putting different voltages into each
channel. What is causing this problem?
The SCXI chassis has backplane fuses. One or both of these fuses could be
blown. Refer to the
Replacing and Checking Backplane Fuses on the
, for fuse replacement information.
Can I programmatically detect whether or not my chassis is
powered on?
Not exactly. You can determine whether or not you can communicate with
configured modules through
SCXI_ModuleID_Read
in NI-DAQ or using
a LabVIEW VI that you can obtain from
ni.com/express
by entering the
info code
rdtscp
.
My chassis will not power on. What should I check?
Check the to make sure the power cord is attached and connected to a power
source. Look at the voltage selection tumbler above the power cord
receptacle and make sure it is set to the correct voltage. Make sure the
power switch is powered on. Verify that the main power fuse is good.
