Network Interfaces

10/100 Ethernet ports—A WXR100 switch has two 10/100BASE-TX
Ethernet ports. A WX1200 switch has eight 10/100BASE-TX Ethernet
ports. Each port has a standard RJ-45 connector and uses Category 5
(Cat 5) cable based on the EIA/TIA-586 standard.
On the WXR100, port 2 can be configured for MAP access points and
can support Power over Ethernet (PoE). Port 1 is an uplink port only
and does not support PoE.
On the WX1200, ports 1 through 6 can be configured for MAP access
points and can support PoE. Ports 7 and 8 on the WX1200 switch are
uplink ports only and do not support PoE.
The 10/100 Ethernet ports on the WX1200, WX2200, and WXR100
switches provide automatic MDI/MDX, which automatically crosses
over the send and receive signals if required.
The WX4400 and WX2200 switches provide high-bandwidth
centralized control of many indirectly connected MAP access points.
The WX4400 switch does not have 10/100 Ethernet ports and does
not provide PoE. The WX2200 has one 10/100 Ethernet port (port 3);
this port does not provide PoE.
Gigabit interface converter (GBIC) slots (WX4400 only)—A WX4400
switch has four ports. Each port has a slot for a 1000BASE-SX or
1000BASE-LX fiber-optic GBIC, and a built-in 1000BASE-TX copper
interface with an RJ-45 connector. Only one interface, copper or fiber,
can be active on a port. The GBIC interface is active by default.
Miniature Gigabit interface converter (mini-GBIC) slots (WX2200
only)—A WX2200 switch has two slots allowing insertion of small
form-factor pluggable (SFP) 1000Base-SX, 1000Base-LX, 1000Base-T,
or 1000Base-LH fiber-optic mini-GBICs to provide gigabit Ethernet
interfaces to the network.
The mini-GBICs have standard SC Duplex connectors and use either
single-mode fiber (SMF) for LX or multimode fiber (MMF) for SX.
Mini-GBICs are available separately and are not included with the
switch.
The gigabit Ethernet ports operate at 1000 Mbps only. They do not
change speed to match 10-Mbps or 100-Mbps links.
