The 3Com
Baseline Switch 2226-PWR Plus is a versatile,
easy-to-use 10/100 layer 2 switch with full Power over Ethernet
(PoE) capabilities. It is ideal for small-to-medium businesses that
want to:
Simplify convergence of data, voice, and wireless networks
today, using existing wiring infrastructure.
Prepare their networks for future expansion from existing
wired LAN to wireless and Voice over IP (VoIP).
The Switch can be used as any other 10/100 L2 switch. But unlike
other switches, its PoE support on all ports enables it to supply
power to IP phones and access points and, at the same time,
connect them to other wired network devices. This PoE capability
removes the need for additional power supplies for your IP
phones and access points.
The Switch has 24 shielded RJ-45, 10/100 Mbps auto-negotiating
ports and two 10/100/1000BASE-T ports. These ports operate in
conjunction with two Small Form Factor Pluggable (SFP)
transceiver slots on the front panel for easy, flexible connection to
fiber-based Gigabit media. All 10/100 Mbps ports are PoE-ready
and IEEE 802.3af compliant. Each port is capable of providing up
to 15.4 watts.
The 10/100 Mbps ports can automatically determine the speed
and duplex mode of the connected equipment and provide a
suitable switched connection. The 1000BASE-T ports also support
automatic 10/100/1000 Mbps speed detection. The 10/100 Mbps
connections on these 1000BASE-T ports operate in half-duplex or
full-duplex mode, while the 1000 Mbps connections operate in
full-duplex mode. The two SFP ports support fiber Gigabit
Ethernet shortwave (SX) and longwave (LX) SFP transceivers in any
combination. This offers you the flexibility of using SFP
transceivers to provide connectivity between the Switch and a
1000 Mbps core network. When an SFP port is in operation, the
corresponding 10/100/1000BASE-T port is disabled.
The Switch is suitable for office use where it can be free-standing
or rack-mounted (in a wiring closet or equipment room).
