HP ProCurve 2910al Series Installation And Getting Started Manual page 11

The 2910al-PoE+ Switches also support Power over Ethernet+ (PoE+)
technology. PoE+ offers a higher wattage per port than the previous PoE
offering, 30 watts per port instead of 15. The switches support 802.3af standard
devices and some pre-standard PoE devices. It also supports the draft version
of the 802.3at standard. For a list of these devices, see the FAQs for your switch
model. This feature is the default and you must disable it if you do not want
to use it. Refer to the Management and Configuration Guide which is on the
ProCurve Web site at www.procurve.com/manuals.
The dual-personality ports have either auto-sensing 10/100/1000Base-T RJ-45,
or mini-GBIC (SFP) connectivity. The mini-GBIC ports do not support PoE. If
any of the mini-GBIC ports are used the corresponding RJ-45 port will not be
supplied with PoE power and will be disabled. For more information regarding
the PoE capabilities of the 2910al Switches, see the ProCurve PoE (Power over
Ethernet) Devices Planning and Implementation Guide, which is on the
ProCurve Web site at www.procurve.com/manuals.
The 2910al Switches can be connected to a ProCurve Redundant/External
Power Supply, RPS/EPS (the ProCurve 620 Redundant and External Power
Supply, J8696A) for redundant power only. If the internal power supply in the
switch fails, the RPS/EPS unit will immediately provide all the power
necessary to keep the switch running. However, the 2910al switches do not
support EPS (PoE+) power from the 620 RPS/EPS. The ProCurve 630
Redundant and External Power Supply (to be released in the future) will
support these switches with EPS (PoE+) power.
These switches are designed to be used primarily as a high-density wiring
closet or desktop switch. These switches can directly connect computers,
printers, and servers to provide dedicated bandwidth to those devices, and
can build a switched network infrastructure by connecting the switch to hubs,
other switches, or routers. In addition, the 2910al Switches offer full network
management capabilities.
