HP E3800-24G-2SFP+ Installation And Getting Started Manual page 27

Auto MDI/MDI-X on all twisted-pair ports (10/100/1000 and 10GBase-T),
■
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. (See the appendices for recommended or required cabling.)
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 the 10/100/1000 RJ-45
■
ports when connected to other auto-negotiating devices—the SFP/SFP+
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 for out-of-band switch management (through the console
port or Management network ports) or in-band 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 Professional Management Center (PMC)—an SNMP-based,
graphical network management tool that 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 2048 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 E3800 Management and Configuration Guide
at www.hp.com/networking/support.
■ Ability to update the switch software. Software updates are routinely
available from HP.
■ An auxiliary port (USB Type A connector) for processing a USB command
file and updating switch software.
Low power operation:
■
• Ports on a switch or stack member may be set to operate at reduced
power.
• Port status LEDs may be turned off.
RJ-45 ports will operate at reduced power if the port is not connected (link
partner is not detected).
