You have a user complaining that their PC only connects at 100Mbps, even though both the PC and the switch support 1Gbps. Run the WDT test.
A standard enterprise switch might enter thermal shutdown at 70°C. A Huawei WDT-certified switch can operate at 85°C ambient air temperature without performance throttling. Similarly, at -40°C, many electronics suffer from latch-up (uncontrolled semiconductor conduction) or solder joint embrittlement. WDT devices undergo rigorous thermal cycling—thousands of transitions from extreme cold to extreme hot—to verify solder joint integrity and electrical performance.
Huawei’s internal testing reports that WDT components reduce thermal-related field failures by over 80% compared to commercial-grade alternatives in the same hostile environments.
WDT is not magic. While the electronics function at -40°C to +85°C, ancillary items like LCD screens, batteries (especially Li-ion), or mechanical connectors may have narrower ranges. Huawei addresses this by segregating sensitive components into protected zones within the device. Additionally, WDT devices are generally heavier and more expensive than standard indoor equivalents due to the robust thermal management hardware.
