To avoid electrical injury, follow instructions in “Installing a Power Supply in an
EX-series Switch” on page 107 and “Removing a Power Supply from an EX-series
Switch” on page 108 carefully.
NOTE: After powering on an EX-series switch, wait for at least 60 seconds before
powering it off. After powering off an EX-series switch, wait for at least 60 seconds
before powering it back on.
After an EX-series 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.
