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).

    HYSICAL EATURES The numbers in this diagram refer to numbered sections in the text. Front Panel 1 24 RJ-45 10/100 Ports WARNING: These are shielded RJ-45 data sockets. They cannot be used as standard traditional telephone sockets, or to connect the unit to a traditional PBX or public telephone network.
  • Page 3 In such a configuration, you may notice some degradation of network performance (see “Troubleshooting“ on page 6). 3Com recommends that you use devices that are capable of auto-negotiation (and that you ensure that auto-negotiation is enabled, if it is a configurable option).

    A PoE-compliant device that has its power supplied over its Ethernet cable no longer requires a separate power supply. If, for example, the Switch is used to connect the 3Com 11 Mbps Wireless LAN Access Point 8500 to the network, then only a network cable is required to provide both power and network connectivity.

    If the SFP transceiver is faulty, it will not operate within the Switch. See “Troubleshooting“ on page 6. Use of non-3Com SFPs is not recommended. If the SFP transceiver is invalid, it will not be recognized by the Switch.
  • Page 7 The fiber cable is in good condition. The SFP transceiver is correctly inserted. A 3Com SFP transceiver is being used. Refer to “Approved SFP Transceivers“ on page 5 for details. The equipment at the other end is installed and correctly configured.
