Hi,

You can use the pxi.chassis_led_blink_pattern attribute to control the behavior of the chassis LED. I did not find a way to change the color. I would expect the code to look something like the following:

import nisyscfg
from nisyscfg.pxi.enums import ChassisLedBlinkPattern

with nisyscfg.Session() as session:
    for resource in session.find_hardware():
        # if resource is PXI chassis ...
        resource.pxi.chassis_led_blink_pattern = ChassisLedBlinkPattern.ONE_BLINK
        resource.save_changes()

Hi,

i tried to run the suggested example and not see any visual effect on our chassis PXIe-1092.
i also tried to change the pattern to THREE_BLINK_BLINK_BLINK and all other combinations, but no effect.

please advice.

thanks,
Nahum

Support for the property was added in PXI Platform Services 20.0. You might check that you have the latest software and firmware installed for the chassis.

• PXIe-1092 Firmware and Additional Drivers
• PXI Platform Services

I do not have hardware to check, but I believe there should be an option in NI MAX to configure the LED. If it shows up there, then this Python module should be able to programmatically adjust it. Otherwise, I would recommend reaching out to NI directly or asking your question to the NI Community.
