Deployment and troubleshooting of ADLINK GIE64+PoE acquisition card

Use PTP testing tools (such as ptp4l, which can be used with vendor tools on Linux and Windows) to verify the synchronization status.

3.3 Common Problems

Large synchronization jitter: Check if the network switch supports PTP (preferably directly connected to the GIE64+port to avoid passing through non PTP switches); Update the firmware of the network card.

Unable to lock master clock: Confirm that all cameras and the PTP version of GIE64+are consistent (v2); Check if the firewall is blocking PTP packets (UDP 319/320).

Link Aggregation

GIE64+supports IEEE 802.3ad link aggregation, which can bundle two or more ports into a single logical link for load balancing and redundancy. The total bandwidth can reach 2Gbps or 4Gbps (depending on the number of ports in the aggregation group).

4.1 Applicable Scenarios

A single GigE bandwidth is insufficient to carry the data streams of high-resolution, high frame rate cameras (such as...) 4K@60fps ）.

Redundant links are required to enhance system reliability.

4.2 Configuration Method

In the operating system, ports 1&2 or 3&4 can be combined into "groups" through the Intel PROSet or NIC Teaming feature.

Note: After aggregation, the camera's IP needs to be configured on the virtual interface of the aggregation group.

Some cameras do not support multiplexing, and it is necessary to confirm whether the camera is compatible with Link Aggregation (usually requiring the camera to support multiple streams or use splitters).

4.3 Performance considerations

The actual throughput is limited by PCIe bandwidth (PCIe x1 2.5GT/s is approximately 250MB/s unidirectional, but GIE64+is x4, theoretically up to 1GB/s, enough for 4 channels of gigabit full speed).

If using link aggregation, it is recommended to enable Jumbo Frame (9KB) at the same time to reduce CPU interrupt load.

Diagnosis and troubleshooting of indicator lights

GIE64+provides rich LED status indicators to quickly locate problems.

5.1 Front panel PoE status LED (yellow, 4)

Always on: The corresponding port PoE power supply is normal.

Extinguish: PoE is not powered (possible reasons: camera not connected, camera power insufficient, overcurrent protection triggered, software shutdown).

5.2 Onboard LEDs (Rear, 9 in total, see Figure 1-7)

LEDs 1-4 (corresponding to data streams from ports 0-3):

Flashing: The downstream function of the PCIe switch chip is normal.

Extinguished: Abnormal (possibly PCIe link not established, driver not loaded).

LEDs 5-8 (corresponding to port data activity):

Always on or flashing: normal.

Extinguish: Abnormal (possibly not recognized by PHY).

LED 9 (global error):

Extinguished: Normal.

Always on: An unexpected error occurred with the PCIe switch chip (possibly due to hardware failure).

Attention: If all LEDs 1-4 are off and LED 9 remains on, it indicates abnormal PCIe connection. Try unplugging the card or replacing the slot; If only a few port LEDs are abnormal, check the physical connection of that port.

5.3 Common Fault Quick Check Table

Possible causes and solutions for the fault phenomenon

The system cannot recognize poor contact in the GIE64+PCIe slot; Driver not installed; BIOS has not enabled the slot to reinsert the card; Install Intel 82574L driver; Check PCIe settings in BIOS

The PoE port has no voltage output and the total load exceeds 20W without connecting to an external power source; Software turns off PoE; PD is not compatible with external 12V power supply connection; Activate API call; Check if the camera complies with 802.3af

The camera cannot obtain IP and the network is not connected; Firewall interception; DHCP failed to check the network cable; Disable firewall; Manually set static IP on the same subnet

Severe network congestion due to image frame loss; CPU overload; Not enabling macro frames, enabling macro frames (9KB); Use link aggregation; Optimize the priority of collection threads

IEEE1588 asynchronous switches do not support PTP; Wrong master-slave settings using direct or PTP switches; Configure the main clock role on the camera end

Link aggregation without bandwidth enhancement. The camera does not support multiple streams; Confirm that the aggregation mode does not match the switch and that the switch supports LACP; Use static aggregation (if supported)

Onboard LED 9 is constantly on, PCIe switch chip error restarts host; If the fault persists, replace the card or contact technical support

After PoE overcurrent, if the fuse is blown and cannot be restored (hardware replacement is required) or if the self recovery fuse is not reset, disconnect all loads and wait for a few minutes; If it still doesn't work, power off and restart the host

Advanced Configuration and Optimization Techniques

6.1 Jumbo Frame

Enabling method: In the Intel PROSet advanced settings, set the "Jumbo Packet" to 9014 bytes.

Requirement: All network ports, switches, and cameras support macro frames, otherwise communication may fail or performance may decrease.

6.2 Disruption of Affinity

In multi-core CPU systems, interrupts from different ports can be bound to different CPU cores to enhance parallel processing capabilities (through task managers or SetIrqAffinity tools).
