ADLINK PXES-2314T Chassis Deployment and Troubleshooting Guide

Strict sequence of power on and off (key)

Due to PXES-2314T communicating with the host via Thunderbolt 3, which involves PCIe hot swapping and power negotiation, a specific power on/off sequence must be followed, otherwise it may result in host blue screen (BSOD), resource conflicts, or device recognition failures.

Correct power on sequence:

Connect the PXES-2314T to the Thunderbolt 3 port of the host PC/laptop using a certified Thunderbolt 3 cable (it is recommended to prioritize connecting to the first Thunderbolt port of the host to ensure system resource reservation).

If necessary, connect other Thunderbolt peripherals (such as storage devices) to another Thunderbolt port of PXES-2314T (supporting daisy chain).

Connect the AC-DC power adapter to the chassis DC input.

Press the power button on the panel, and the blue Power LED will light up.

Open the host PC and start Windows 10.

Open the Thunderbolt control center of the host and set PXES-2314T as an authorized device that is "always connected" to ensure automatic recognition each time.

Correct power-off sequence:

Shut down the host PC/laptop normally.

Disconnect Thunderbolt 3 cables from both ends of the host and chassis.

Press the power button on the front panel of the chassis to turn off the chassis.

It is strictly prohibited to hot plug Thunderbolt cables or replace modules while the system is powered on. Even though the Thunderbolt protocol itself supports hot plug, many PXI module drivers have not been optimized for dynamic resource allocation, and hot plug can easily cause kernel crashes or device unavailability. In addition, when the host is connected to the chassis through Thunderbolt and the chassis is powered on, the front panel power button will be locked and cannot be directly turned off - this is designed to prevent accidental disconnection, and the host must be turned off and the Thunderbolt cable disconnected before the button can be unlocked.

Intelligent monitoring and ChassisWatch configuration

PXES-2314T integrates ChassisWatch ™ The monitoring tool (included in the ADLINK PXI Platform Services software package) communicates with the chassis management unit through Thunderbolt links to monitor three temperature sensors (T1~T3, located as shown in the backplane diagram), two fan speeds, and all DC voltage rails in real-time.

4.1 Status Monitoring Interface

After starting ChassisWatch, the main interface displays:

DC Voltage: Current readings and status (normal/abnormal) of+5V,+3.3V,+5V,+12V, and -12V.

Chassis Temperature: Three sensors provide real-time temperature, with a default alarm threshold of 70 ° C (adjustable).

Fan Speed: Rear fan speed (RPM), default low threshold is 800 RPM.

If any parameter exceeds the threshold, the corresponding LED (temperature amber, fan green, power blue) on the front panel will flash, and specific alarm items can be viewed in the software.

4.2 Smart Fan and Target Temperature Setting

The front panel is equipped with a fan switch (High/Auto):

High: Disable intelligent control, fan fixed maximum speed (noise 52.8 dBA).

Auto: Enable intelligent speed regulation and dynamically adjust based on sensor temperature.

In Auto mode, the default fan curve is:

When all temperature readings are below 25 ° C, the fan runs at 40% speed;

When any temperature exceeds 25 ° C, the speed begins to increase linearly;

When the maximum temperature reaches the target temperature, the fan reaches 100% speed.

Users can modify the target temperature value in ChassisWatch (default 70 ° C, adjustable range 25 ° C~70 ° C). If the system load is high or the ambient temperature is too hot, the target temperature can be lowered (e.g. 55 ° C) to allow the fan to run at full speed earlier, but the noise acceptance needs to be balanced.

4.3 Triggering I/O and Bus Configuration

The front panel provides SMB trigger I/O ports, which can be programmed through software to route external trigger signals to the backplane trigger bus (8 trigger lines) or output in reverse. Supports four modes:

Select trigger line → SMB output

Input from SMB → Select trigger line

Software trigger → Select trigger line

Software trigger → SMB output

This feature is very useful when synchronizing multiple instruments or triggering external events, and the related API is provided by the PXI Trigger Management service.

Common troubleshooting and practical solutions

This chapter summarizes the most commonly encountered problems and systematic troubleshooting methods in on-site use, all based on the FAQ and troubleshooting table in the manual.

5.1 The system cannot recognize the chassis or peripherals

Check Thunderbolt Connection: Confirm that the cable is a certified Type-C Thunderbolt cable (with ⚡ Insert the Thunderbolt port into the host (instead of a regular USB-C port). You can check if PXES-2314T is detected in the Thunderbolt control center of the host.

Check power supply: Is the DC input voltage within the range of 9-32V? Does the adapter output sufficient power? If the input voltage is below 9V, the chassis cannot start.

Check driver installation: Has ADLINK PXI Platform Services been installed? This software includes necessary Thunderbolt bridge drivers and resource managers.
