Power Over Ethernet (PoE) Operation for the Series 5300xl Switches

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.

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-config-

ured 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.
