PXI-1042 Chassis power switch LED is steady red
When attempting to turn on the PXI-1042 Chassis, the power switch LED turns steady green for ~2 seconds, and then turns steady red and remains in this state. All modules were removed (PXI-8330, PXI-6704, PXI-5411, LeCroy PXD 1021 digitizer) with the AC plug removed, and when powering up the chassis again with the AC plug re-inserted, the LED went through the same process, remaining at steady red. This issue arose after our building underwent a power outage, and during this outage the chassis was in standby mode, the AC power plug was still attached to the chassis, but the power to the surge protector (to which the other end of the AC power plug was attached) was turned off. To my knowledge, there were no surges when power to the building was restored. Does anyone know what could be causing this problem (possible power surge?), and can it be remedied/repaired? Thanks.
Thanks for the advice. I contacted NI but they were unable to offer a cheap replacement fan, nor is our part still under warranty, but I was able to get in touch with the fan manufacturer to get the identical one (Mechatronics P/N: E9225X12B1FSR). It actually runs on 12 VDC and has a tachometer output, which I'm assuming the chassis reads to determine whether or not to power up all of the attached devices.

How to connect to PXI 1042 chassis from PC
I bought PXI 1042 with two RF switches and now I am trying to connect from my PC in order to manage it.
I am not shure, that I have connection with my PXI 1042, how can I verify connection?
PXI 1042 has two RF switches in slots 2,3 and I cann't see them from Measurement & Automation Explorer.
Could you help me?
ThanksYou would require a MXI link to do that.
Read about it here -
I have a CD-ROM with file chassis.sys that came with the PXI-1042. How is that file used/installed?
Hi,
The "chassis.ini" file contains information which is used to generate a "pxisys.ini" file, which describes a unique combination of PXI chassis and controller. If you are using a National Instruments PXI controller, you will not need to use this "chassis.ini" file, because our Measurement and Automation Explorer (MAX) configuration software already contains the necessary information embedded. Instead, you simply need to setup your configuration in MAX.

PXI 1010 Chassis power failed.
Now one PXI 1010 backplane power failed on PXI section, but SCXI side can power on.I ever checked nad reset circuit breaker, no help. I need your help! Who will give me a kind hand?
Roger,
If you have already checked the circuit breaker and have verified that it is not tripped, more than likely there is a power failure with the PXI portion of the power supply. I would create a phone service request at www.ni.com/ask. We can only handle returns through our phone support. At that point, if you indicate that you have a damaged product, we can work with you to get it fixed.

Hi
I'm trusting my specs appear in my sig ......
I'm not sure how to procede as the PSU would appear OK but the mobo is not replying "power up !"
TIA
SteveIs the power switch of your case (power button) properly connected to the board's JFP1 pin header?
If yes, take the board out of the case and put in on a non-conducting surface. Try barebone configuration for testing:
- CPU (reseat CPU and heatsink)
- video card (make sure it is in the slot closest to the CPU)
- one stick of RAM in slot 1 (try the other one as well)
- Keyboard
- power connectors
- power-on switch (case)
Remove everything (unplug from both, PSU and mainboard): hard drives, optical drives, X-FI card, USB Front panel connectors, all other devices.
Make sure the board's strap jumpers (JB1/JB2) are properly jumpered to 200 MHz FSB clock speed.
After unplugging devices and before your next start-up attempt, make sure you clear CMOS with main A/C power cable removed from PSU. >>Clear CMOS Guide<<
The 24-Pin ATX connector of your PSU has a removeable 2x2-Pin part. Make sure you have not confused that part with the +12V-CPU connector in the right picture. I am saying that because this happened to someone the other day. The symptoms were similar.
Also, your PSU only has a 4-Pin +12V CPU plug (picture on the right). The board's 8-Pin connector can be used with 4-Pin Plugs. Just make it is plugged into that part of the connector that is not covered by a plastic cap on the following picture:

PXI Chassis Power LED Flashing Red: What to do?
My NI PXI-1042 keeps blinking red the Power LED. I know it means the voltage is out of the specs. What to do?
FilipeTaveiros wrote:
But it is not continuously red.. It is blinking red.. Thanks for your help. Anyone?
This is copied right out of the manual:
The chassis power switch has an integrated LED. This LED indicates one
of three different conditions:
• If the power switch LED is steady green (not flashing), the chassis is
powered on and operating normally.
• If the power switch LED is flashing green, the air-intake temperature
has exceeded the chassis operating range.
• If the power switch LED is flashing red, the power supply outputs are
not within voltage regulation requirements.
You either have a power supply problem, or you are loading it down with too many modules. Try running it empty and see what the light does.

PXIe-1075 Power switch will not turn off chassis
Hi,
I think I am having trouble turning my PXIe-1075 chassis off with the front mounted power switch. When I press the power switch, the green LED will ficker and the PWR LED on my PXIe-8360 MXI card will flicker from green to red and then back to green. I have a PXI-1042 chassis as well that seems to turn off properly. The switch on my PXI-1042 chassis has two positions, but the switch on my PXIe-1075 only seems to have one position. I am in a spot where I will need to power off my chassis to move it occasionally. Does it sound like my PXIe-1075 chassis has an issue? Am I missing something? I also tried holding the power switch. This will cause all the installed modules active light to turn off, but the PWR light on the switch and the PWR light on the MIX card will stay the same.Hello,
The 1075 has two modes for shutdown. You can select between the modes with the 'inhibit' switch on the back of the chassis. When this switch is in the default position, the chassis will power down when you shut down the controller in the chassis (I'm not sure if it will automatically power down with the MXI connection when you shutdown the PC- I do not believe it will). When the switch is in the manual position, the chassis does not shut down with the controller and you must use the Inhibit signal on pin 5 of the Remote Inhibit and Voltage Monitoring connector. I believe your chassis is in 'Manual' mode. More information on this is available in the manual on page 2-12:
http://www.ni.com/pdf/manuals/372537b.pdf
I do not think that the power button on the front can be used to power off the chassis.

845 Ultra Ver.1 (N1996) Power Switch Pin & Led
Hi to all,
I appreciate if u could help me regarding my main board problem. I bought this main board way back year 1997, if i’m not mistaken. My PC still running & work perfectly w/ OS windows 7 ultimate. Unfortunately my Power Supply spoilt & change w/ new one. My problem is, i can’t find my Manual & i don’t where did i take out the power supply switch & power light on the main board, due to no caption on board. Is there any web site that I can down load? I really appreciate if could help me to identify where can i plug the power switch & led.
Thanks & CheersNot too much info on which model 845 ultra you have as there are some OEM versions of that board
also, but here MSIs manual:

Bonjour, Suite à une coupure de courant nous avons eu des soucis avec l'alimentation de notre PXI-1042 (led d'alimentation qui été verte quelques secondes puis clignote rouge ainsi de suite).Suite a ceci nous avons voulu vérifier le fusible et avons tiré la languette (a l'arrière du châssis "circuit breaker 10A"), elle est désormais en position ou l'on peut voir un élément blanc. Le problème est qu'elle ne reste plus en position initiale (partie noir seulement visible).Pourriez vous me donner plus d'information à ce sujet? Ainsi qu'au sujet de la led rouge? Merci d'avance de toute réponse me permettant de faire progresser mon problème.
Tiré du USER MANUAL :
Resetting the AC Mains Circuit Breaker
If the PXI-1045 is connected to an AC source and encounters an
over-current condition, the circuit breaker on the rear panel will trip to
prevent damage to the chassis. Complete the following steps to reset the
circuit breaker.
1. Set the front-panel power switch to the Off (nonrecessed) position.
2. Disconnect the AC power cable.
3. Depress the circuit breaker to reset it.
4. Reconnect the AC power cable.
5. Set the power switch to the On (recessed) position.
If the circuit breaker trips again, complete the following steps.
1. Press the front-panel power switch to the Off (nonrecessed) position.
2. Disconnect the AC power cable.
3. Remove all modules from the chassis.
4. Complete the procedure described in the Connecting to Power Source
section of Chapter 2, Installation and Configuration. If the power
switch LED is not a steady green, contact National Instruments.
5. Verify that the PXI-1045 can meet the power requirements of your
CompactPCI or PXI modules. Overloading the chassis can cause the
breaker to trip. Refer to Appendix A, Specifications.
6. The over-current condition that caused the circuit breaker to trip may
be due to a faulty CompactPCI or PXI module. Refer to the
documentation supplied with the modules for troubleshooting

Hello!I have a NI PXI 1042 chassis.I want to make a voltage diagnose via serial port in the back of the chassis. Can I use Adlink chassis remote mon. application and as a cable to use serial to usb (Wenglor AB-USB01) converter?Do you know this Adlink application is compatible to NI PXI 1042 chassis?Also this cable I use it's ok, or I must have necessary RS-232 port on my laptop and use only standard RS232 cable?
You really should read the manual (NI PXI-1042 Series User Manual). That is NOT a serial port. It is a connector that will allow you to measure the backplane voltages and apply a power supply inhibit (ie remotely turn off the chassis) using a relay.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Fix for PXIe-1075 Chassis 3.V V Drift?
I have a PXIe-1075 chassis which is exhibiting the type of voltage drift behavior described in Document ID 52DD5OL3. The serial number matches with the numbers described in the document as one of a series which should be returned to NI for repair.
As I'm on quite a tight budget, and the unit was purchased used (on Ebay), I'm wondering if anyone out there has any familiarity with this problem, and the manner of repair required. I'm assuming that warranties are way out on this one. I might attempt the repair myself.
The KnowledgeBase document suggests that the problem is related to a connector problem on the PXIe-1075 chassis power shuttle. Can anyone suggest more specifically which connector is the problem, and how it might be corrected by a capable, enthusiastic, and adventurous engineer?
Thanks!
JonHello Grandmaster_P!
The unit's S/N: V08X16632
Once again, this unit was purchased second-hand. Can I still get warranty work on it? It was originally a part of NI's RF road show, but ended up on ebay a few years back, where I purchased it from a freight recovery warehouse in Salt Lake City, UT.
If it was not covered, have you any idea what this sort of repair might cost?
Thanks!

I have several modules in a PXI-1042 chassis that I am tring to route the same trigger to [on the PXI-Trig0 line]. I am using the VISA Map Trigger VI, but I cannot seem to get it to work without error. I am trying to use the front panel trigger from the PXI-8501 module [resource name PXI11::13::INSTR] as the souce and the PXI-Trig0 as the destination.
Since the VISA Map Trigger does not accept VISA sessions of class INSTR, how do you map a trigger from an instrument to the backplane?
Thanks.
