Huawei H20-923_V1.0 Exam - Topic 9 Question 19 Discussion

On Huawei UPS systems (such as the UPS5000 series), the MDU LCD panel includes status indicators designed to provide an immediate visual understanding of the UPS operating condition and alarm severity. The indicator system uses three standard colors: green, yellow, and red. Green indicates the UPS is operating normally and the power supply path is healthy. Yellow is used to show abnormal conditions that require attention, such as warnings or non-critical alarms, where the UPS can typically continue supplying power but O&M personnel should inspect and handle the issue within the required timeframe. Red indicates serious or critical conditions, such as major faults or alarms that may threaten continuous power supply or require urgent action according to operating procedures. These three colors align with the common Huawei alarm severity presentation logic on the UPS display and help technicians quickly judge whether the situation is normal, warning-level, or critical-level without entering deeper menus. Orange is not used as an MDU indicator color in this context.
