correct hardware-related problems in your system.

LED Indications
There are two alarm types, major and minor. Major alarms indicate a critical problem that could lead to
the system being shut down. Minor alarms are for informational purposes only, giving you notice of a
problem that could turn critical if corrective action is not taken.
When the system has an alarm (major or minor), indicating an overtemperature condition, the alarm is
not canceled or any action taken (such as a module reset or shutdown) for 5 minutes. If the temperature
falls 5°C (41°F) below the alarm threshold during this period, the alarm is canceled.
