to 30W per port to power IP phones, wireless access points, indoor web cameras, and more.
For more information, see the HPE Power over Ethernet (PoE/PoE+) Planning and
Implementation Guide, available from http://www.hpe.com/networking/support.
The switches support 802.3af and 802.3at standard devices and some pre-standard PoE
devices. For a list of these devices, see the FAQs (Frequently Asked Questions) for your
switch model. PoE is enabled by default. (For instructions, see the 3810M Management and
Configuration Guide for your switch at http://www.hpe.com/networking/support.
The option to have one or two internal power supplies.
A second power supply supports redundant system power and/or redundant/additional PoE
power. If one of the internal power supplies fails, the second power supply immediately
provides the power necessary to keep the switch running, including PoE+ power on an
allocated basis.
If maximum PoE+ power is used on the 48 port PoE+ switch, the second power supply is
needed for PoE+ power but there is no PoE power redundancy. However, system power is
always maintained. On a power supply failure, the system drops the PoE power on ports
based on user priority, to maintain system power. For more information on Power Supplies,
see Power
Plug-and-play networking—all ports are enabled by default—just connect the network cables
to active network devices and your switched network is operational.
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 64000-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 or in-band switch management.
◦
Web browser interface—An easy to use built-in graphical interface that can be accessed
from common web browsers.
◦
IMC—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 4096 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 3810M Management and Configuration Guide at
support.
Ability to update the switch software. Software updates are routinely available from Hewlett
Packard Enterprise.
