Introducing the Switch
Switch Features
1-14
Power over Ethernet (PoE/PoE+) operation—the E2620-PoE+ Switches
■
are IEEE 802.3at compliant and provide up to 30W per port to power IP
phones, wireless access points, web cameras, and more. For more
information, see the HP Power over Ethernet (PoE/PoE+) Planning and
Implementation Guide, which is on the HP Web site at
networking/support.
■ The E2620-PoE+ Switches support some pre-standard PoE devices.
However, the use of a cross-over cable may be required. For a current list
see the FAQ page for the E2620-PoE+ Switch, which can be found on the
HP Web site, www.hp.com/networking/support.
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, 10/100 and 10/100/1000, 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 and
10/100/1000 RJ-45 ports when connected to other auto-negotiating
devices—the mini-GBIC ports always operate at full duplex, unless a
100-FX SFP transceiver is installed. The 100-FX SFP transceiver can
operate at half duplex.
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 512 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.
Variable-speed fans to maintain cooling.
■
Support for many advanced features to enhance network performance—
