Chapter 2 Switch Installation
Connecting Devices to the Ethernet Ports
Connecting to the 10/100 PoE Ports
The Cisco IE-3010-16S-8PC switch 10/100 PoE ports have the same autonegotiation settings and
cabling requirements as those in the
“Connecting to the 10/100 and 10/100/1000 Ports” section on
page 2-25. These ports provide PoE power.
See the “PoE Ports” section on page 1-3 for information on the cables and connectors.
The ports provide PoE support for devices compliant with IEEE 802.3af and also provide Cisco
prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
On a per-port basis, you can control whether or not a port automatically provides power to a connected
IP
phone or an access point.
To access an advanced PoE planning tool, use the Cisco Power Calculator on Cisco.com:
http://tools.cisco.com/cpc/launch.jsp
You can use this application to calculate the power supply requirements for a specific PoE configuration.
The results show output current, output power, and heat dissipation.
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
Caution Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables
to a suitable and safe earth ground before connecting them to the switch or other devices.
