WARNING!
This equipment is intended for intra-building. Intra-building connections are defined as cable runs that are located
in the same building as the unit.
This equipment can be connected between buildings if one of the following requirements are met:
●
Cable runs less then 140ft between buildings
●
Cable runs between buildings are directly buried.
●
Cable runs between buildings are in an underground conduit, where a continuous metallic cable
shield or a continuous metallic conduit containing the cable is bonded to each building grounding
electrode system.
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 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:
●
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, AC power, or DC power requirements of the
network equipment.
●
Ensure that DC connections are made by an on-site electrician.
●
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.
