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.
Both LEDs can be lit simultaneously.
You can view the colors of the two LEDs remotely through the CLI by issuing the

Network Port and Uplink Port LEDs in EX2200 Switches
Each network port and uplink port on the front panel of an EX2200 switch has two LEDs
that indicate link/activity and port status. Each dual-purpose uplink port in an EX2200-C
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 Figure 9 on page 14,
Figure 10 on page 15, and Figure 11 on page 15.
