OVERVIEW
The PoE L2 Managed 10/100 Switch is an ideal choice for your
large, managed enterprise network. It packs 24 autosensing
10/100 Ethernet ports into a compact chassis that takes only 1U
of rack space. Two dual-media ports function as 10/100 Ethernet
ports or as SFP slots for fiber uplinks.

The switch features full SNMP management plus manage-
ment over any IP network using your Web browser. And when
you add the versatility of Power over Ethernet, you have a truly
versatile switch that grows with your network.

Power over Ethernet.
The switch acts as a PoE power source device, enabling you
to supply power to PoE end devices such as wireless access
points, CCTV cameras, and VoIP phones on your 10-/100-Mbps
network. By using PoE, you free yourself from restrictions
imposed by limited AC outlets and you can centralize your
power distribution and backup power.

network. By using PoE, you free yourself from restrictions
imposed by limited AC outlets and you can centralize your
power distribution and backup power.
The 24 autonegotiating PoE ports provide up to 15.4 watts
for 12 ports or 7.7 watts each for all ports, up to a total of
185 watts. The switch 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 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-Mbps copper Ethernet port or you can
use it to plug in an SFP to create a fiber uplink.

use it to plug in an SFP to create a fiber uplink.
Choose 1250-Mbps SFPs for Gigabit Ethernet; choose
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 inte-
grate into any managed network. Built-in Web management
enables you to manage the switch using a 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.

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.

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.
