Site Preparation
For more information about the power specifications of the Extreme Networks family of switches, see
Appendix B, “Switch Technical Specifications”.
Power Supply Requirements
Adhere to the following requirements in order to operate your Extreme Networks equipment safely:
• Make sure your equipment is placed in an area that accommodates the power consumption and
component heat dissipation specifications.
• Make sure your power supply meets the site power, AC power, or DC power requirements of the
network equipment.
• Make sure DC connections are made by an on-site electrician.
NOTE
For power specifications for Extreme Networks products, see the Extreme Networks website at
http://www.extremenetworks.com.
• When connecting power to installed equipment, avoid connecting through an extension cord or
power strip.
• If your switch includes more than one power supply, connect each power supply to different,
independent power sources. If a power source fails, it will only affect 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.
AC Power Cable Requirements
Use an AC power cable appropriate for your country. Check your local electrical codes and regulatory
agencies for power cable requirements. The countries listed in Table 7 and Table 8 have the additional
requirements.
NOTE
When using dual power supplies, make sure that each AC power supply attaches to an independent
power source.
