Planning and Implementation for the HP 2520
and HP 2520G Switches
Introduction
This chapter discusses the planning process you should follow to successfully
implement PoE using an HP 2520 or HP 2520G Switch. See “General
Considerations” on page A-1 for an example list of considerations during the
planning phase.
HP 2520-PoE Switches
The HP 2520-8-PoE Switch (J9137A), has 8 PoE-integrated auto-sensing 10/
100Base-TX RJ-45 ports with two dual-personality gigabit uplink ports.
The HP 2520-24-PoE Switch (J9138A), has 24 PoE-integrated auto-sensing 10/
100Base-TX RJ-45 ports and two 10/100/1000Base-T uplink ports, with two
dual-personality gigabit uplink ports.
These switches also support some pre-standard PoE devices. For a list of these
devices, see the FAQs for your switch model. This feature is enabled by
default.
The dual-personality ports have either auto-sensing 10/100/1000Base-T
RJ-45 or SFP connectivity. The dual-personality ports do not support PoE.
