Power Supply in EX3300 Switches
The power supply in EX3300 switches is built in along the rear panel of the chassis, with
an AC power cord inlet or DC power terminal block on the rear panel to connect power
to the switch.
NOTE: After powering on the switch, wait for at least 60 seconds before
powering it off. After powering off the switch, wait for at least 60 seconds
before powering it back on.
After the switch has been powered on, it can take up to 60 seconds for status
indicators—suchasshow chassis command output and messages on the LCD
panel—to indicate that the power supply is functioning normally. Ignore error
indicators that appear during the first 60 seconds.
Table 13 on page 21 lists the power consumed by each EX3300 switch model. The
maximum power available on a PoE+ port is 15.4 W.
