The 2910al-PoE+ Switches also support Power over E (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.hp.com/go/procurve/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.hp.com/go/procurve/manuals .
HP ProCurve Redundant/External Power Supplies (RPS/EPS) can be
connected to the 2910al Switches for redundant 12 V system power (RPS) and
to provide for additional PoE+ provisioning. For RPS power, the 2910al
Switches can be connected to either an HP ProCurve 620 RPS/EPS or HP
ProCurve 630 Redundant and/or External Power Supply. But, for additional
PoE+ EPS power, only the HP ProCurve 630 RPS/EPS can be used. The 620
does not provide 54 V for PoE+, only 50 V for PoE, and the 2910al Switches do
not support connections to the 620 for EPS.
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.
