NOTE: After powering on an EX3200 or EX4200 switch, wait for at least 60 seconds

before powering it off. After powering off an EX3200 or EX4200 switch, wait for at

least 60 seconds before powering it back on.

After an EX3200 or EX4200 switch has been powered on, it can take up to 60 seconds

for status indicators—such as LEDs on the power supply, show chassis command

output, and messages on the LCD—to indicate that the power supply is functioning

normally. Ignore error indicators that appear during the first 60 seconds.
