The front panel of an EX3200 switch has three LEDs on the far right side of the panel,
next to the LCD panel (see Figure 9 on page 19).

Table 5 on page 19 describes the chassis status LEDs in an EX3200 switch, their colors
and states, and the status they indicate. You can view the colors of the three LEDs
remotely through the CLI by issuing the operational mode command

A major alarm (red) indicates a critical error condition that requires immediate action.
A minor alarm (amber) indicates a noncritical condition that requires monitoring or
maintenance. A minor alarm that is left unchecked might cause interruption in service or
performance degradation.
NOTE: The amber glow of the Alarm LED that indicates a minor alarm closely resembles
the red glow that indicates a major alarm.
All three LEDs can be lit simultaneously.
