CAUTION: You must use the correct power supply cover panel to ensure
airflow of the power supplies installed in the switch.
NOTE: If you are upgrading your EX6200 switch from 2500 W AC power
supplies to the 5000 W AC power supplies, you must order the 5000 W AC
power supply cover panels separately.
Each power supply has its own fan and is cooled by its own internal cooling system. The
airflow is from the front of the power supply to the back. Hot air exhausts from the rear
of the chassis.
We recommend an N+1 redundancy configuration for normal operation of EX6200
switches. In an N+1 redundancy configuration, if one power supply fails or is removed,
the remaining power supplies (N) continue to supply power for the switch without
interruption.
You can determine the minimum number of power supplies needed (N) for a switch and
then install an additional power supply to meet the required N+1 redundancy configuration.
For details about different switch configurations, see
on page 7 .
Table 27 on page 44 lists the N+1 power requirements of EX6210 switch configurations
that use 2500 W AC and 5000 W AC power supplies.
