Repeat the above steps to install multiple modules. After completion, it is necessary to install filling panels in all empty slots, otherwise it will significantly reduce heat dissipation efficiency and may cause overheating alarms in the chassis.
Power supply and power on process
PXES-2301 has a built-in universal power supply, eliminating the need for manual voltage switching. Correct power on steps:
Connect one end of the random power cord to the C13 power inlet at the back of the chassis;
Insert the other end into a grounded wall socket or PDU (Power Distribution Unit);
Press the power button on the front panel, and the blue Power LED should immediately light up;
Press the power button again when shutting down.
If it needs to be idle for a long time, it is recommended to disconnect the power cord and store it in a dry and clean environment.

Intelligent Monitoring System - ChassisWatch Configuration and Use
PXES-2301 integrates ADLINK ChassisWatch ™ Remote monitoring tool that communicates with the chassis management unit through the SMBus of the system slot to monitor temperature, fan speed, and all DC voltage rails in real-time. The monitoring software can be downloaded and installed from the official ADLINK PXI platform service package. After installation, it is necessary to ensure that the PXI Resource Manager is activated, otherwise the monitoring program cannot run normally.
4.1 Connection and Control Interface
After starting ChassisWatch, the interface is divided into three main areas:
Connect Control: Click "Connect" to occupy SMBus, then click "Start" to initialize communication; After completing the operation, click "Stop" to end the communication, and then click "Disconnect" to release the bus.
Chassis Status Log: supports data recording, can set the log file name (overwrite or append), sampling period (seconds), and optional "Over Threshold Statistics" to record over threshold events.
Save/Load Threshold: You can save all current threshold settings as a file, load existing configurations, and restore default thresholds with just one click.
4.2 Temperature target value and fan mode
The rear of the chassis is equipped with a physical fan switch (HIGH/AUTO):
HIGH: The fan runs at full speed, suitable for high temperature environments or full load testing, but with high noise (60.8 dBA sound pressure level).
AUTO: Dynamically adjust speed based on internal temperature sensor readings. The default fan curve is: when the temperature of all sensors is below 25 ° C, the fan runs at 30% speed; After any sensor exceeds 25 ° C, the speed increases linearly; When the maximum temperature reaches 65 ° C (i.e. "Target Temperature"), the fan reaches 100% speed.
Users can modify the target temperature value (range 25 ° C~65 ° C) in the software, for example, setting it to 55 ° C can make the fan enter full speed earlier, which is suitable for module combinations with higher heat dissipation requirements. After setting, click "Set" to take effect immediately.
4.3 Alarm threshold setting
The monitoring panel can independently set alarm thresholds for the following items:
DC voltage: 5V Standby, 3.3V, 5V, 12V, -12V;
Temperature: Equipped with three sensors T1~T3 (located at the air inlet, middle of the back panel, and air outlet), the default upper temperature limit is 70 ° C;
Fan speed: An abnormality is triggered when it falls below the lower limit of the set speed.
If any parameter exceeds the threshold, the corresponding status light will change to "Abnormal", and the corresponding LED on the front panel (blue power supply, green fan, amber temperature) will flash an alarm.
Practical Guide to Troubleshooting and Maintenance
This section summarizes common on-site fault phenomena and their systematic troubleshooting methods to help engineers quickly locate problems.
5.1 System cannot start
Firstly, confirm:
The power cord should be securely inserted into the chassis and socket, and the socket should have electricity;
The system controller is installed in place and the fixing screws are tightened;
All peripheral modules are fully inserted into the backplane without tilting;
Module type and chassis compatibility (PXI Express/CPCI Express/Hybrid PXI-1);
If all of the above are normal, remove all peripheral modules and only keep the system controller for attempting to start. If successful, insert modules one by one and restart each time to identify the faulty module; You can also try replacing the slot to rule out hardware issues with the slot.
5.2 External monitor without video output
Confirm that the power and signal lines of the monitor are connected properly;
Check the display output settings of the system controller (such as whether to switch to an external graphics card);
Try replacing the monitor or cable to troubleshoot the external device.
5.3 Abnormal LED indicator light
Blue Power LED flashing: indicates power failure or abnormal backplane communication. If it persists after restarting, please contact technical support.
Green Fan LED flashing: The fan may be blocked by foreign objects or the speed may be too low. Firstly, turn off the power and check if there is any dust or cable obstruction at the bottom fan inlet; If the signal is not restored after cleaning, the fan module needs to be replaced (removable, easy to maintain).
