ADLINK DLAP-5200 series AI engine deployment and optimization

Fix the heat sink screws with a torque controlled between 0.4~0.6 N · m to prevent cracking of the GPU die.

Common problem: GPU cannot recognize after booting up. Check if the MxM connector is in place and if the power cord (if there is an auxiliary power supply) is securely plugged in; Check if 'Primary Display' is set to PEG in BIOS (if necessary for GPU output).

Practical deployment of network and TSN configuration

DLAP-5200-6DP integrates Intel I225-IT controller, providing 6 2.5GbE ports, all of which support Time Sensitive Networking (TSN). TSN is crucial in industrial real-time Ethernet (such as EtherCAT, Profinet over TSN).

4.1 Hardware Port Mapping

Ports 0-2 may be bound to the first I225 controller, while ports 3-5 may be bound to the second controller (depending on hardware design).

Under Linux, each controller can be identified through lspci nn | grep 225, and driver information can be viewed using ethtool - i ethX.

4.2 TSN Enabling Steps (Ubuntu 22.04)

Install Linux tools common and Intel i225 tsn drivers (to be downloaded from Intel's official website).

Load the IGC driver (I225 uses the IGC module) and enable TSN Qbv/Qbu functionality:

bash

sudo modprobe igc

sudo ethtool --set-tsn eth0 on

Use tsntool (provided by Intel) to configure the gating list and cycle.

Attention: All TSN devices need to synchronize their clocks (PTP) and install ptp4l and phc2sys to achieve precise time synchronization.

4.3 Troubleshooting

Unstable network connection: Check if the network cable supports Cat6 or above; 2.5G speed requires high-quality cables. If the cable is poor, the speed can be reduced to 1G (ethtool-s eth0 speed 1000 duplex full).

TSN gate control not effective: Confirm that the kernel version is ≥ 5.15 and options such as VNet NET_SCH_CTF have been configured.

GPU module driver and performance tuning

The MxM module (A4500/A2000) uses NVIDIA official drivers. Installation steps:

Download the driver for Ubuntu 22.04 (version ≥ 525).

Disable Nouveau: Create/etc/modprobe. d/blacklist nouveau. conf, add blacklist nouveau, and update initramfs.

Run sh NVIDIA Linux - *. run -- no opengl files (to avoid conflicts with the desktop).

Perform Nvidia SMI verification after installation.

Performance tuning:

Set persistent mode: nvidia smi pm 1.

Adjust GPU frequency and power upper limit (root required): Nvidia smi pl 60 (limit of 60W).

If used for AI inference, it is recommended to enable MIG (only supported by A4500, not supported by A2000) and split the GPU into multiple instances.

Common faults:

GPU fan not running (if the GPU comes with a built-in fan): Check the hardware connection or manually set the speed through Nvidia smi ac (but in a fanless design, the GPU relies on system cooling and no independent fan is normal).

GPU overheating and frequency reduction: Monitor temperature (nvidia smi -- query gpu=temperature. gpu), if it exceeds 85 ℃, increase external airflow.

BIOS key settings (based on R680E chipset)

The BIOS (AMI UEFI) of DLAP-5200 can be accessed by pressing DEL during startup. The following key items must be checked:

6.1 Memory Configuration

XMP: If using high-frequency DDR5 (such as 4800), XMP Profile needs to be enabled in "Memory Overclocking", otherwise it defaults to running at the base frequency (4400 or lower).

Memory Remap: Enable (default) to ensure that 64 bit systems can use all memory.

6.2 Processor Power Consumption Limitations

Go to "CPU Configuration" → "Power Limit 1"/"Power Limit 2":

Set PL1=35W and PL2=45W (short-term) for 35W CPU.

Set PL1=65W and PL2=90W for the 65W CPU (but ensure sufficient heat dissipation).

Turbo Mode: It is recommended to enable it, but if the temperature is too high, Turbo can be disabled to reduce peak power consumption.

6.3 Display output priority

The 'Primary Display' option can be either 'Auto' (Priority PEG) or 'IGFX' (Ensemble Display). If using GPU output and requiring BIOS graphics, PEG should be selected.

Multi monitor: DLAP-5200 provides 2 x HDMI (one from MxM and one from integrated display) and 3 x DP (from MxM), and requires "Multi Monitor" support to be enabled in the BIOS.

6.4 TSN and Network Wake up

In "PCH-IO" → "PCI Express Configuration", ensure that each PCIe Root Port (corresponding to I225 controller) is enabled.

If WOL is required, enable "Wake on LAN" and set "Power On by PCIe".

6.5 Serial port mode

DLAP provides 2 RS-232/422/485 configurable serial ports (COM1/COM2). In the "Super IO Configuration", set the modes (RS-232/422/485) separately, and note that automatic direction control (usually handled by the driver) needs to be set for RS-485 half duplex.

6.6 Watchdog

Built in hardware watchdog, which can set a timeout value (in seconds) in "WatchDog". If the system times out and does not feed the dog, it will automatically reset. It is recommended to set the production environment to 120 seconds.
