PoE+ and Cisco UPOE Port Connections

PoE+ and Cisco UPOE Port Connections
The 10/100/1000 PoE+ and Cisco UPOE ports have the same autonegotiation settings and cabling requirements
that are described in the
Cisco UPOE inline power.
PoE inline power supports devices compliant with the IEEE 802.3af standard, as well as prestandard Cisco
IP Phones and Cisco Aironet Access Points. Each port can deliver up to 15.4 W of PoE. PoE+ inline power
supports devices compliant with the IEEE 802.3at standard, by delivering up to 30 W of PoE+ power per port
to all switch ports.
See Power Supply Modules
on 24- and 48-port switches.
Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections
are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such
interconnection methods, unless the exposed metal parts are located within a restricted access location
and users and service people who are authorized within the restricted access location are made aware of
the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key
or other means of security. Statement 1072
Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is disrupted.
Warning
After power is restored, you might have to reset or reconfigure equipment to regain access to VoIP and
the emergency calling service. In the USA, this emergency number is 911. You need to be aware of the
emergency number in your country. Statement 371
Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to
Caution
a suitable and safe earth ground before connecting them to the switch or other devices.
Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling
