Power Over Ethernet (PoE+) Operation
Planning and Implementing a PoE Configuration
Planning and Implementing a PoE
Configuration
This section provides an overview of some considerations for planning a PoE
application. For additional information on this topic, refer to the ProCurve
PoE Planning and Implementation Guide
which is available on the ProCurve
Networking web site at www.procurve.com. (Click on Customer Care, then
Manuals).
Some of the elements you may want to consider for a PoE installation include:
■ Port assignments to VLANs
■ Use of security features
■ Power requirements
This section can help you to plan your PoE installation. If you use multiple
VLANs in your network, or if you have concerns about network security, you
should read the first two topics. If your PoE installation comes close to (or is
likely to exceed) the system’s ability to supply power to all devices that may
request it, then you should also read the third topic. (If it is unlikely that your
installation will even approach a full utilization of the PoE power available,
then you may find it unnecessary to spend much time on calculating PoE
power scenarios.)
Assigning PoE Ports to VLANs
If your network includes VLANs, you may want to assign various PoE ports
to specific VLANs. For example, if you are using PoE telephones in your
network, you may want to assign ports used for telephone access to a VLAN
reserved for telephone traffic.
Applying Security Features to PoE Configurations
You can utilize security features built into the switch to control device or user
access to the network through PoE ports in the same way as non-PoE ports.
