• On steadily—Junos OS for EX Series switches
has been loaded on the switch.
• Blinking—The switch is boong.
• O—The switch is powered o or is halted.
ALM Red There is a major alarm.
NOTE: When you connect power to the switch, the
alarm LED (ALM) glows red. This behavior is
normal. Plugging an acve Ethernet cable into the
management port (MGMT) on the switch completes
the network link and turns o the ALM LED. (See
Connect a Device to a Network for Out-of-Band
Management .)
Connecng the switch to a dedicated management
console instead of a network does not aect the
ALM LED. The LED remains red unl the switch is
connected to a network.
Yellow There is a minor alarm.
NOTE: The ALM LED glows yellow if you commit a
conguraon to make it acve on the switch
without creang a rescue conguraon to back it
up. To save the most recently commied
conguraon as the rescue conguraon, enter the
operaonal mode command request system
configuration rescue save.
Unlit There is no alarm or the switch is halted.
