Extreme Networks BlackDiamond 10808 Installation Manual page 30

When connecting power over Ethernet (PoE) devices to a PoE switch, all connections between the PoE
device and the switch must remain within the same building and use a low-voltage power distribution
system per IEEE 802.3af.
Adhere to the following requirements to operate your Extreme Networks equipment safely:
Ensure that your equipment is placed in an area that accommodates the power consumption and
component heat dissipation specifications.
Ensure that your power supply meets the site power or AC power requirements of the network
equipment.
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 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.
For power specifications for Extreme Networks products, see the Extreme Networks website at:
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
requirements.
