Power Switch LED Indicators
The chassis has two LEDs next to the power switch. The system power
LED indicates the power status for the chassis. The SCXI power LED,
when lit, indicates that power is available to the SCXI subsystem. The
system power LED indicates one of three different conditions.
1. If the system power LED is steady green (not flashing), the chassis is
powered on and operating normally.
Caution Operating the PXI system outside of the specified temperature range can result in
loss of data, reduction of chassis life, or damage to equipment.
2. If the system power LED is flashing green, the air-intake temperature
has exceeded the chassis operating range. Complete the following
steps:
a. Power off the system.
b. Unplug the AC power cable.
c. Inspect the chassis for ventilation obstructions and clear them.
d. If the condition persists, contact NI using the information in the
front of this manual.
Caution Power supply output voltages out of regulation can result in equipment
malfunction, incorrect data, or failure of system to boot.
3. If the system power LED is flashing red, the PXI power supply
outputs are not within voltage regulation requirements. Complete
the following steps:
a. Power off the system.
b. Unplug the AC power cable.
c. Inspect the chassis for physical damage.
d. Verify that the there is no issue with the AC supply feed to the
PXI-1052 chassis.
