In Huawei smart module commissioning, the ECC800-Pro controller provides a dedicated management access path through its WAN ports. For on-site startup commissioning, technicians typically connect a laptop directly toWAN1and place the laptop IP address in the same subnet as the controller so they can open the WebUI and complete initial settings (time, network, device discovery, alarm checks, linkage tests, and parameter commissioning). Thefactory default IP address for WAN1 is 192.168.8.10, which is used as the initial access point before the address is planned and changed to match the customer’s management network. This default design supports quick “point-to-point” commissioning without depending on upstream switches, DHCP services, or enterprise IP planning at the very beginning of deployment. After login, Huawei commissioning practice is to harden access (password/authentication completion), then update network parameters and integrate the ECC800-Pro into the site monitoring network to enable continuous O&M, remote alarm reporting, and device management.

In Huawei data center facility equipment (such as precision cooling units and related controllers), alarm presentation follows a clear severity-based design so technicians can recognize urgency immediately without entering detailed menus. Acritical alarmrepresents the highest severity level and is treated as a condition that may impact safe operation, cooling continuity, or equipment protection. For this reason, the LCD controller uses the most prominent visual and audible indications: theindicator turns redto show critical severity, and thebuzzer sounds continuouslyto ensure the alarm cannot be overlooked in a noisy equipment-room environment. This behavior supports rapid response: O&M personnel can quickly identify that immediate action is required, then open the alarm list to locate the root cause, confirm whether the unit has derated or stopped, and execute the prescribed troubleshooting steps (for example, checking power status, sensor readings, fan/compressor status, water flow/pressure, and protection interlocks). Therefore, the statement correctly describes the standard critical-alarm indication method on the LCD controller.
