Switch Features
The features of the 2520G-PoE switches include:
■ 8, or 24 auto-sensing 10/100/1000Base-T RJ-45 ports with Auto-MDIX.
■ Two, or four dual-personality uplink ports (1000Base-T RJ-45 or mini-
GBIC).
■ Power over Ethernet (PoE) operation—the switches are IEEE 802.3af
compliant and provide up to 15.4W per port to power IP phones, wireless
access points, Web cameras, and more. For more information, see the PoE
Planning and Implementation Guide, which is on the ProCurve Web site
at www.hp.com/go/procurve/manuals.
■ The switches support some pre-standard PoE devices. However, the use
of a cross-over cable may be required.
■ Plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.
■ Auto-MDIX on all twisted-pair ports, meaning that all twisted-pair
connections can be made using straight-through cables. Cross-over cables
are not required, although they will also work.
■ Automatic learning of the hardware addresses in each switch’s 8000-
address forwarding table, (with configurable address aging value).
■ Automatically negotiated full-duplex operation for the 10/100/1000 RJ-45
ports when connected to other auto-negotiating devices.
■ a “Save Power” mode option that keeps port LEDs turned off except for
when the LED Mode select button is pressed.
■ an automatic low-power mode for ports when a link is not present.
■ Easy management of the switches through several available interfaces:
• console interface—a full featured, easy to use, VT-100 terminal
interface that is especially good for out-of-band switch management
or for Telnet access to the switch.
• Web browser interface—an easy to use built-in graphical interface
that can be accessed from common Web browsers.
• ProCurve Manager—an SNMP-based, graphical network
management tool that you can use to manage your entire network.
■ Support for the Spanning Tree Protocol to eliminate network loops
■ Support for up to 256 IEEE 802.1Q-compliant VLANs so you can divide
the attached end nodes into logical groupings that fit your business needs.
■ Download of new switch software for product enhancements or bug fixes.
