Table 120: Chassis Status LEDs on an EX4300 Switch (continued)
LED Label Color
MST (Primary) Green
A major alarm (red) indicates a critical error condition that requires immediate action.
A minor alarm (yellow or 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.

LEDs on EX4300 Switches
Each 10/100/1000BASE-T network port, SFP network port, SFP+ uplink port, SFP+ uplink module port,
built-in QSFP+ port, and QSFP+ uplink module port on an EX4300 switch has two LEDs that show the
link activity and status of the port.
The following figures in this topic shows the location of those LEDs:
