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

performance degradation.
Both LEDs can be lit simultaneously.
You can view the colors of the two LEDs remotely through the CLI by issuing the
operational mode command show chassis led.

switch has two pairs of LEDs that indicate the link/activity status, one pair for each of
the two ports that constitute the dual-purpose uplink port. See
