Planning Considerations
This appendix is divided into three sections:

These lists are in no way exhaustive, however answers to these and other
questions will help define how many and what types of switches are needed
to implement a PoE configuration.
General Considerations
The following is an example list of considerations during the planning phase
no matter which series of switches are being installed:

General Considerations
Specific Considerations for the 3500yl Switches
Specific Considerations for the 5400zl Switches
How many devices need PoE power?
What devices will need PoE power?
How much power will each device require, in watts?
What is the total of all their wattages?
Will the devices be connected to a 3500yl or to a 5406zl switch?
How many ports are needed?
How many ports are available?
Are the devices to be powered by PoE power supported?
•
The ProCurve Series 5400zl Switches support any products that meet
the IEEE 802.3af PoE standard and some pre-standard PoE devices.
For a current list see the FAQ page for your switch, which can be
found on the ProCurve Web site, www.procurve.com, Technical
Support, FAQs (all).
How many PDs per Switch?
•
The number of PDs supported per switch depends on the power
allocation and how much power each PD uses and how much power
is left. The examples in the following section show the power
consumption in some typical configurations.
