Introducing the Switch
Introducing the Switch
The 2910al-24G Switch and 2910al-48G Switch have respectively, 24 or 48,
auto-sensing 10/100/1000Base-T RJ-45 ports, four dual-personality ports—
either auto-sensing 10/100/1000Base-T RJ-45 or mini-GBIC, and two slots are
provided in the back of the device to support expansion modules:
■2-port (two fixed CX4 ports) 10 Gigabit per second Ethernet (10-GbE)
module.
■2-port 10-GbE SFP+ (Small Form Factor Pluggable) module. The specifi-
cation for SFP+ defines the physical and electrical characteristics of this
form-factor (size and shape). The form-factor is identical to SFP, but the
SFP+ is a 10-Gigabit Ethernet transceiver.
■1-port 10-GbE interconnect module.
Table 1-1. These products support optional network connectivity with the
following speeds and technologies:

Introducing the Switch
Introducing the Switch
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 802.3atstandard. For alist 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.

Network Ports
■24 or 48 auto-sensing 10/100/1000Base-T ports.
All these ports have the “Auto MDIX” feature, which means you can use
either straight-through or crossover twisted-pair cables to connect any
network devices to the switch.
■On the 2910al devices there are four dual-personality ports. Use either the
10/100/1000Base-T RJ-45 connector, or install a supported ProCurve mini-
GBIC (SFP) for fiber-optic connections.
The RJ-45 connectors support the “Auto MDIX” feature, which means you
can use either straight-through or crossover twisted-pair cables to
connect any network device to the switch.
Dual-Personality Port Operation. By default, the RJ-45 connectors are
enabled. If a mini-GBIC is installed in a slot, it is enabled and the associ-
ated RJ-45 connector is disabled and cannot be used. If the mini-GBIC is
removed, the associated RJ-45 port is automatically re-enabled.
The RJ-45 connector also supplies PoE+ power until a mini-GBIC is
installed. The PoE+ power is turned off when a mini-GBIC is plugged in.
■Two expansion slots. These switches provide two slots in the back of the
device that can accept any of the al modules. The module provides port
connectivity for 10 gigabit speed. The module ports provide connectivity
through either copper or fiber optic media.

■The PoE+ switches have an additional mode, PoE. In PoE mode, the Link
LED indicates the PoE configuration for the port:
• On if PoE is enabled on the port
• Off if PoE is disabled on the port.
■Each port has a Link LED. If it is lit, the port has a link. If the Link LED is
Flashing, the port has failed its self test. The Fault and Self Test LEDs will
be Flashing simultaneously.
■If the Activity (Act) indicator LED is lit, each port LED displays activity
information for the associated port—it flickers as network traffic is
received and transmitted through the port.
■If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those
ports that are operating in full duplex.
■If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows
to indicate the connection speed for the port:
• Off = 10 Mbps
• Flashing = 100 Mbps (the Flashing behavior is a repeated on/off cycle
once every 0.8 sec.)
• On = 1000 Mbps
