M10i HCM Alarm LEDs
Two alarm LEDs are located on the right of the HCM (see M10i HCM LEDs). The circular red LED lights to indicate a critical condition that can result in a system shutdown. The triangular yellow LED lights to indicate a less severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously.
To deactivate red and yellow alarms, you must clear the condition that caused the alarm.
Table 1 describes the alarm LEDs in more detail.
