Table 33: SYS, ALM, and MST Chassis Status LEDs on EX4400 Switches (Connued)
LED Label Color State and Descripon
In a Virtual Chassis conguraon:
• On steadily—The switch is the primary switch in the
Virtual Chassis conguraon.
• Blinking—The switch is funconing as the backup
switch in the Virtual Chassis conguraon.
• O—The switch is a linecard member in the Virtual
Chassis conguraon or the switch is halted.
NOTE: Issuing request system power-off doesn't power-o the SYS LED, which connues to blink. It
is because this command will power-o only the CPU board. As CPU board asserts plaorm
reset during shutdown process, it will trigger SYS LED to enter default state of blinking. This is
expected behavior.
LEDs on the Management Port on EX4400 Switches
The management port—labeled MGMT—has two LEDs that indicate link acvity and status of the port
(see Figure 45 on page 65 and Figure 46 on page 66). The management port is on the rear panel of
EX4400 switch models except the EX4400-24X model. The management port is on the front panel of
the EX4400-24X model.
