Wizard startup commissioning is designed to verify that the unit’skey controllable subsystemscan be started, regulated, and protected correctly. Conditions that prevent a subsystem from operating normally will directly cause commissioning failure. If thecondensate pump is stuck, the drainage function cannot be validated and water may accumulate in the drain pan, which is treated as a functional fault during commissioning. Ifindoor fan 2 drive is faulty, the fan system cannot meet airflow requirements or redundancy expectations, so the fan commissioning item fails. If theelectronic expansion valve (EEV) is not opened, refrigerant flow and cooling control cannot be established, so the cooling system commissioning fails because the unit cannot build a stable refrigeration cycle or reach expected operating parameters.

In contrast, thewater leakage ropeis aprotective detection accessoryused for leak sensing and alarming. While it is important for site safety and recommended for operation, its absence typically does not block the unit from completing the functional commissioning steps for fans, cooling, and drainage; it mainly affects leak detection coverage and related alarms rather than the basic startup commissioning pass/fail.

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 lithium battery cabinet alarm design, the MDU indicator and buzzer are coordinated to help O&M personnel immediately judge alarm severity without logging into a management system. Acritical alarmindicates that the battery system may no longer be in a fully safe or supported operating state and requires urgent handling, such as load protection actions, isolation, or immediate inspection. For this highest severity level, the cabinet uses the most prominent visual pattern:red with fast blinking, paired with acontinuous buzzer, to ensure the condition cannot be overlooked in an equipment room environment. Yellow indicators are reserved for lower severities such as warnings or minor/major alarms, where the system remains controllable and the required response can be scheduled. A steady red is typically used to indicate a persistent fault state or stop condition, whereasfast blinking red + continuous buzzeris the clear “critical, urgent” combination that triggers immediate on-site response and rapid fault localization (such as checking protection events, contactor status, temperature/voltage exceptions, and isolation conditions).
