Planning and Implementation for the Series
3500yl Switches
This chapter discusses the planning process a user should follow to
successfully implement PoE using a Series 3500yl Switch. After understanding
what PoE is and its operating rules, the next step to implementation is
planning. See “Specific Considerations for the 3500yl Switches” page A-2, for
an example list of considerations during the planning phase.
Planning Your PoE Configuration
This section assists you in building a PoE configuration. Using the following
examples you can plan, build, and connect PoE devices quickly and easily.
There are four configurations:
■ ProCurve Switch 3500yl-24G-PWR
■ ProCurve Switch 3500yl-24G-PWR connecting an external power supply.
■ ProCurve Switch 3500yl-48G-PWR
■ ProCurve Switch 3500yl-48G-PWR connecting an external power supply.
Each example shows a complete configuration. A table shows the PoE power
available to connected PoE devices when using just the switch.
Once you have selected your specific configuration and the PoE power
provided, you then add up the maximum amount of power each device
requires (use maximum power in watts, usually found on a product’s data
sheet). Adjust this total maximum power figure by adding 15% to account for
possible line loss. This value must be less than the maximum power available
shown in the table for your configuration.
