OVERVIEW
The PoE L2 Managed Gigabit Switch provides power plus
high-speed Gigabit throughput to your network devices.
It’s an ideal choice for bandwidth-sensitive applications such as
VoIP and video. And with 12 autosensing 10-/100-/1000-Mbps
Ethernet ports, two SFP slots for Gigabit uplinks, plus a full array
of management features in a 1U rackmount chassis, it packs a
lot of performance into a small package.
What’s more, management is easy with full SNMP
management capabilities, plus you can manage the switch
over any IP network using your Web browser.
Power over Ethernet.
Power over Ethernet (PoE) sends power across the unused
pairs in CAT5 (or better) UTP cable. By using PoE, you can
centralize power distribution without the need for additional
infrastructure to supply power—no need for a nearby power
outlet. The switch provides a total of 135 watts of power to the
12 PoE ports, which support end devices such as CCTV cameras
and VoIP phones. It autodetects device and consumption levels,
supports per-port consumption monitoring, and prevents power
on one port from interfering with the other ports.
Dual-media SFP ports for extra versatility.
Two ports on each switch are dual-media ports with two
connectors each—one RJ-45 Ethernet and one SFP. You can
use a dual-media port as an ordinary 10-/100-/1000-Mbps copper
Ethernet port or you can use it to plug in an SFP to create a
fiber uplink.
Choose 1250-Mbps SFPs for Gigabit Ethernet; use 155-Mbps
SFPs for 10- or 100-Mbps Ethernet. All SFPs report SFP type,
length of fiber link, wavelength, and bit rate. Models with
extended diagnostics also report information such as
temperature, TX and RX power, voltage, and bias current.
A full range of management and security features.
SNMP v1 and v2 support makes the switch easy to
integrate into any managed network. Built-in Web
management enables you to manage the switch using
a standard Web browser over any IP network—even the
Internet.
Port mirroring helps to track network errors and abnormal
packet transmission by forwarding a copy of each incoming
and outgoing packet to another switch port where you can
examine it with a protocol analyzer.
MAC-based 802.3ad LACP link aggregation enables you
to combine six Gigabit ports for 12-Gbps bandwidth on a
single trunk. In all, the switch supports up to six trunking
groups. Automatic failover ensures that data isn’t sent to
failed ports, but will instead go to remaining active ports.
802.1x Access Control provides user authentication. Port
security enables you to limit the number of MAC addresses
per port. You can also define static MAC addresses for each
port so only registered devices can access those ports.
QoS and VLAN, too!
The switch supports QoS with two internal priority
queues, enabling you to provide prioritization where it’s
required, making it particularly ideal for switching packets
in real-time VoIP applications. The switch classifies packets
to one of two priorities using Layer 4 TCP/UDP port and
ToS classification.
The switch supports port- or tag-based VLAN with up to
256 active VLANs. 802.1ad (Q-in-Q) VLAN stacking or double-
tagging provides user isolation and service identification
so multisite enterprises can create and maintain private
VLANs for separate departments within the structure of
their corporate wide-area VLAN.

Twisted-pair Ethernet cable, in addition to carrying data,
can also provide electrical power to low-wattage electrical
devices through a method called Power over Ethernet (PoE).
PoE delivers low-level power—roughly 13 watts at 48 VDC—
over CAT5 or higher copper Ethernet cable to PoE-enabled
devices such as IP telephones, wireless access points, Web
cameras, and audio speakers.
How PoE works.
Ethernet cable that meets CAT5 (or better) standards consists
of four twisted pairs of cable, and PoE sends power over these
pairs to PoE-enabled devices.
In PoE mode A, power and data are sent over the same pair.
Because electricity and data function at opposite ends of the
frequency spectrum, their transmissions don’t interfere with
each other. Electricity has a low frequency of 60 Hz or less,
and data transmissions have frequencies that can range from
10 million to 100 million Hz. This method injects both power
and data on pairs 3 and 6 and pairs 1 and 2.
In PoE mode B, two wire pairs are used to transmit data,
and the remaining two pairs are used for power. This method
can be used for 10BASE-T and 100BASE-TX which transmit data
on two pairs, but cannot be used with Gigabit Ethernet which
uses all four pairs for data transmission.
Basic structure.
There are two types of devices involved in PoE
configurations: Powered Devices (PD) and Power Sourcing
Equipment (PSE).
PDs are devices such as surveillance cameras, sensors,
and wireless access points that operate on PoE.
PSEs provide power to PDs over the Ethernet cable.
PSEs include mid-span and end-span devices. A mid-span
device (often called a power injector) goes between a
network switch and a PD and puts power onto the Ethernet
cable. An end-span device is often a PoE-enabled network
switch that’s designed to supply power directly to the cable
from each port, eliminating the need for a separate switch
and power injector.
PSEs provide power in either PoE mode A or B. PDs accept
power in either mode.
PoE applications.
Power over Ethernet is ideal for providing power to low-
wattage network devices such as surveillance cameras, wireless
access points, and VoIP phones. Most VoIP phones made today
support PoE, enabling them to receive uninterrupted power
through the network without the need for an AC outlet for
each phone. With the addition of network backup power,
VoIP phones will continue to function even during a blackout.
