ADLINK PXES-2314T Chassis Deployment and Troubleshooting Guide

BIOS/System Settings: Some laptops require Thunderbolt support to be enabled in the BIOS and the "Security Level" to be turned off or set to "Not Encrypt" to allow unauthorized devices.

5.2 Pressing the power button cannot shut down

This is a normal protection mechanism. When the host is connected via Thunderbolt and the chassis is powered on, the power button is locked to prevent accidental data loss. Correct operation: First, shut down the host operating system, disconnect the Thunderbolt cable, and then press the power button to shut down. If a forced shutdown is urgently needed, the DC power input can be disconnected.

5.3 Blue Power LED flashing

Indicates that the voltage rail exceeds the threshold or there is a short circuit. All peripheral modules should be disconnected first, leaving only the empty chassis powered on, and observing whether the LED is normally on. If it is constantly on, install each module one by one and investigate which module is causing overcurrent. If the empty chassis still flashes, it may be a power module failure and technical support needs to be contacted.

5.4 Green Fan LED flashing

Indicates that the fan speed is below the set threshold (default 800 RPM). First, check if there are any foreign objects blocking the rear fan inlet or if the cables are entangled. If it still flashes after cleaning, you can check the actual speed in ChassisWatch. If the speed is too low, the fan bearing may be aging and the fan module (detachable design) needs to be replaced.

5.5 Amber Temperature LED Flashing

Firstly, confirm whether the heat dissipation gap on both sides is ≥ 101.6 mm and whether all filling panels are installed.

Sensing the exhaust temperature (on the right side) with your hand, if it is noticeably hot, it may indicate that the ambient temperature is too high or the module power consumption exceeds the limit.

If the exhaust air temperature is normal (below 70 ° C) but the LED flashes, it may be that the threshold setting is too sensitive, and the high temperature alarm threshold can be adjusted in ChassisWatch.

If the temperature is indeed too high, you can temporarily turn the fan switch to "High" to force full speed cooling, and check if there are any individual modules that are abnormally heating up.

5.6 Analysis and Solution of Windows Blue Screen (BSOD)

Blue screens are usually caused by hot swapping operations or drivers that do not support dynamic resource allocation. Troubleshooting steps:

Enable Windows full memory dump and reproduce the issue to generate dump files.

Use MongoDB to analyze dump and locate the driver module that triggered the blue screen.

However, it should be noted that the trigger point may not necessarily be the root cause - often a certain driver crashes first when resources conflict. The correct approach is to fully comply with the standard power on and off sequence and avoid any hot swapping behavior.

If a specific module must be used and its driver is known to have compatibility issues, you can contact the manufacturer for updates or use compatibility mode.

Maintenance and long-term reliability recommendations

6.1 Cleaning and Inspection

After turning off the power, use a dry soft cloth to wipe the outside of the chassis, focusing on cleaning the dust accumulation on the left air inlet and right air outlet. If there is a lot of dust in the environment, you can regularly (every 3 months) open the top cover of the chassis (using professional tools) and blow the fan and heat sink with compressed air, but be careful not to touch the backplane connector.

6.2 Handling and Storage

When moving, be sure to use the top handle, which is structurally reinforced to withstand the weight of the entire machine. The storage environment has a temperature range of -40 ° C to 71 ° C and a humidity of 10% to 90% (without condensation), which is much wider than the operating conditions, but should be avoided from being placed in high humidity or corrosive gas environments for a long time.

6.3 Firmware and software updates

Regularly visit the ADLINK official website to download the latest PXI Platform Services and MAPS Core versions, which may include Thunderbolt compatibility improvements, fan control algorithm optimizations, and new fault diagnosis features. Back up the ChassisWatch threshold configuration file before updating to quickly restore personalized settings.

Performance validation and reference data

To assist users in evaluating the system status, the following key test indicators are listed:

Thunderbolt effective bandwidth: When using PCIe Gen3 x4 links, the theoretical unidirectional bandwidth is about 3.94 GB/s, and the measured sustainable transmission is ≥ 3.5 GB/s (affected by the host and cable).

Temperature linearity: The temperature difference between the three sensors (inlet, middle plate, and outlet) is usually within 5-10 ° C. If the outlet sensor is higher than the inlet by more than 15 ° C, it indicates that the module power consumption is too high or the air duct is blocked.

Noise level: 35.7 dBA in Auto mode and 52.8 dBA in High mode, suitable for laboratory environments; If sensitive to noise, try to use Auto mode and maintain an ambient temperature of ≤ 25 ° C.
