Planning and Implementation for the
HP 2910-PoE+ al Switches
Introduction
This chapter discusses the planning process you should follow to successfully
implement PoE+ using an HP 2910-PoE+ al Switch. After understanding what
PoE+ is and its operating rules, the next step to implementation is planning.
See “General Considerations” on page A-1 for an example list of
considerations during the planning phase.
HP 2910-PoE+ al Switches
The HP 2910-48G-PoE+ al Switch (J9148A) has 44 PoE+ integrated, auto-
sensing 10/100/1000Base-T RJ-45 ports with four dual-personality gigabit
uplink ports.
The HP 2910-24G-PoE+ al Switch (J9146A) has 20 PoE+ integrated, auto-
sensing 10/100/1000Base-T RJ-45 ports with four dual-personality gigabit
uplink ports.
These switches also support some pre-standard PoE devices. While HP strives
to support as many non-standard devices as possible, some devices in the
market are designed in ways that are restrictive, or exclusive of the IEEE
standard and thus cannot be supported. For a list of these devices, see the
FAQs for your switch model at www.hp.com/networking/support, and click on
faqs. This feature is enabled by default. It you do not want to use it, you must
disable it by issuing the following command via the switch CLI:
