System Management Module LEDs

The following table describes the SMM LED indicators:

FortiGate-7121F SMM LEDs
LED State Description
Status Off The SMM is powered off or not initialized.
Solid red The SMM is not operating normally either because it is starting up or because it has failed.
Blinking red The active SMM cannot communicate with the passive SMM.
Solid green The SMM has started up and is operating normally.
Blinking green The SMM is passive.
Alarm Off No alarms
Red One or more analog sensors in the chassis or on a module in the chassis (other than PSUs) have surpassed a critical or non-recoverable (NR) threshold causing an alarm. When a critical threshold has been reached, it means that a condition has been detected that has surpassed an operating tolerance. For example, a temperature has increased above the allowed operating temperature range.
Amber One or more analog sensors in the chassis or on a module in the chassis (excluding PSUs) has surpassed a major or critical (CR) threshold. Any sensor, including sensors on PSUs, has generated an alert. Sensor alert criteria is defined per sensor. For analog sensors, alerts usually mean passing an upper critical (UC) or lower critical (LC) threshold. For other sensors, an alert could mean a flag bit is indicating an anomaly.
Temp Solid green All temperature sensors indicated acceptable operating temperatures.
Blinking green At least one temperature sensor is detecting a high temperature outside of the normal operating range. In this case an upper non-critical (UNC) temperature. The SMM increases fan speed to increase cooling and reduce the temperature.
Blinking red At least one temperature sensor is detecting a temperature outside of the acceptable operating range. In this case an upper critical (UC) temperature. The SMM increases fan speed to the maximum level. This also indicates possible problems with the cooling system and could mean that the ambient temperature is too high. Also causes a major or critical (CR) alarm.
Solid red At least one temperature sensor is detecting a temperature outside of the allowed operating range. In this case an upper non-recoverable (UNR) temperature. The SMM increases fan speed to the maximum level. The temperature is high enough to potentially cause physical damage. Also causes a critical or non-recoverable (NR) alarm.
Power Solid green Normal operation.
Blinking green Chassis 12V disabled. This means that the administrator has entered commands into the SMM CLI to power off the PSU main 12V outputs. All fans, FIM and FPM modules are completely powered off but the SMM is still running.
Red Chassis 12V enabled but not OK. This means the SMM has enabled the main 12V outputs for all chassis components, but the power OK (PWOK) signal of at least one PSU has not been sent. When a PSU is powering up, it would be normal for this LED to be red for a second (before PSU outputs are stabilized), but if LED remains red, it indicates a problem (such as a failed PSU). SMM or FIM or FPM module voltage sensors would most likely also trigger alarms if this happens since the PSUs may not be delivering enough power.

FAN (LEDs for each of six fan trays)

Off Fan tachometer sensors disabled. This could happen if the administrator disabled them from the SMM CLI.
Green The fan tray is operating normally.
Red A fan tachometer sensor in this fan tray has registered an alert because a critical or non-recoverable (NR) threshold has been crossed.

PSU

Off The PSU is not installed in the chassis.
Green The PSU is present and operating normally.
Blinking red The PSU module is installed but no power is being delivered (not plugged in).
Red The PSU's sensors have detected an alert condition. The PSU's analog sensors crossed critical or non-recoverable (NR) thresholds, or the PSU Status Failure bit has been set.
Console 1 and 2 Off This console port is not connected or is connected to the SMM SMM CLI.
Green This console port is connected to this module host console in this chassis slot.
Amber This console port is connected to this module's SMC console.
