Extreme Networks VSP 4900 Series User Manual

To prevent RF interference, avoid the following situations:
• Attaching UTP cable to AC power cables
• Routing UTP cable near antennas, such as a ham radio antenna
• Routing UTP cable near equipment that could exhibit RF interference, such as ARC
welding equipment
• Routing UTP cable near electrical motors that contain coils
• Routing UTP cable near air conditioner units
• Routing UTP cable near electrical transformers
In areas or applications where these situations cannot be avoided, use ber optic
cabling or shielded twisted pair cabling.
Meet 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 specications.
• 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.
For detailed power specications for your equipment, see "Technical Specications."
