The power supplies are rated to output up to 650 W (AC power supplies) or up to 930 W (DC power supplies),
but the switch requires less than those amounts of power from the power supply. To operate the switch, you
must provision enough power from the power source to cover the requirements of both the switch and a power
supply. Typically, this switch and a power supply require about 232 W of power input from the power source,
but you must provision as much as 455 W power input from the power source to cover peak demand.
Some of the power supply modules have Underwriter Labs (UL) rating capabilities that exceed the switch
requirements. When calculating your power requirements, use the switch requirements to determine the amount
of power that is required for the power supplies.
Note
To minimize the possibility of circuit failure, make sure that each power-source circuit that is used by the
switch is dedicated to the switch.
For AC input application, please refer to the following statement:
Note
Statement 1005—
Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the
protective devices are rated not greater than 20A (North America), 16A (Europe), and 13A (UK).
Warning
For DC input application, please refer to the following statement:
Note
Statement 1005—
Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent) protection.
• Ensure that the protective devices are rated not greater than 40A when the switch is powered with regular
DC power supplies (rated 48-60VDC).
• Ensure that the protective devices are rated not greater than 10A when the switch is powered with HVDC
power supplies (rated 240-350VDC).
Warning
For the power cables to use with the power supplies, see
