Switch Features
The features of the Switch 2800 Series devices include:
■ 24 or 48 auto-sensing 10/100/1000Base-T RJ-45 ports.
■
four dual-personality ports—either the auto sensing 10/100/1000Base-T
RJ-45 or the mini-GBIC can be used for each port.
■ plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.
■
both switches support an external Redundant Power Supply (RPS).
■ IEEE 802.3ab Auto MDI /MDI-X on all 10/100/1000 twisted-pair ports,
meaning that
all connections can be made using straight-through
twisted-pair cables . Cross-over cables are not required, although they
will also work. The pin operation of each port is automatically adjusted
for the attached device: if the switch detects that another switch or hub
is connected to the port, it configures the port as MDI; if the switch detects
that an end-node device is connected to the port, it configures the port as
MDI-X.
■
automatic learning of the network addresses in each switch’s 8000-
address forwarding table, (with configurable address aging value).
■ automatically negotiated full-duplex operation for all 10/100/1000Base-T
RJ-45 ports when connected to other auto-negotiating devices—the mini-
GBIC ports always operate at full duplex.
■
easy management of the switch 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.
• HP ProCurve Manager —an SNMP based, graphical network
managent tool you can use to manage your entire network. this
product is included with your new switch.
■
support for the Spanning Tree Protocol to eliminate network loops.
■ support for up to 60 IEEE 802.1Q-compliant VLANs so you can divide the
attached end nodes into logical groupings that fit your business needs.
■ support for many advanced features to enhance network performance—
for a description, see the
Management and Configuration Guide, which
is on the Documentation CD-ROM included with the switch.
■ download of new switch software for product enhancements or bug fixes.
