Uninterruptible Power Supply Requirements
PoE Devices
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 must use a low-voltage power
distribution system per IEEE 802.3af.
Power Supply Requirements
Adhere to the following requirements to operate your Extreme Networks equipment safely:
●
Be sure that your equipment is placed in an area that accommodates the power consumption and
component heat dissipation specifications.
●
Be sure 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.
