Follow these recommendations when you plan power supply connections for your equipment:
Place the equipment in an area that accommodates the power consumption and component heat dissipation specifications.
Be sure that your power supply meets the site DC power or AC power requirements of the network equipment.
When you connect power to installed equipment, do not make this connection through an extension cord or power strip.
If your switch includes more than one power supply, connect each power supply to a different, independent power source.
If a power source fails, it will affect only the switch power supply to which it is connected. If all switch power supplies are connected to a single power source, the entire switch is vulnerable to a power source failure.
In regions that are susceptible to electrical storms, the best practice is to plug your system into a surge suppressor.
