LEDs

Check your device's QuickStart guide for specific LED information: FortiGate QuickStart Guides.

The following faceplates show examples of where the LEDs are typically found on FortiGate models:

The following tables list the possible LED states and their meanings. Not all devices include every LED or support every state.

Alarm levels

Minor alarm

Also called an IPMI non-critical (NC) alarm, it indicates a temperature or power level outside of the normal operating range that is not considered a problem. For a minor temperature alarm, the system could respond by increasing the fan speed. A non-critical threshold can be an upper non-critical (UNC) threshold (for example, a high temperature or a high power level) or a lower non-critical (LNC) threshold (for example, a low power level).

Major alarm

Also called an IPMI critical or critical recoverable (CR) alarm, it indicates that the system is unable to correct the cause of the alarm, and that intervention is required. For example, the cooling system cannot provide enough cooling to reduce the temperature. It can also mean that the conditions are approaching the outside limit of the allowed operating range. A critical threshold can also be an upper critical (UC) threshold (such as a high temperature or high power level) or a lower critical (LC) threshold (such as a low power level).

Critical alarm

Also called an IPMI non-recoverable (NR) alarm, it indicates that the system has detected a temperature or power level that is outside of the allowed operating range and physical damage is possible.
