Meeting Power Requirements
Observe the following requirements and precautions for powering your hardware.
Power Supply Requirements
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, we recommend that you plug your system into a
surge suppressor.
