We recommend that you occupy all power supply slots of the switch with power supplies. In case a power
module fails, it is recommended to retain the failed power module in its slot until it is replaced with a new
power module. This recommendation ensures that the system airflow is not impacted adversely, which may
then result in the overheating of the switch and its components.
Note
A dual pole breaker is needed for installation. For determining the recommended breaker size, please adhere
to local and national rules and regulations. The breaker size is based on the specifications of the product for
the current drawn and the specified voltage level.
Note
