14 CHAPTER 1: WX SWITCH OVERVIEW
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 switch provide automatic
MDI/MDX, which automatically crosses over the send and receive
signals if required.
A WX4400 switch provides high-bandwidth centralized control of
many indirectly connected MAP access points. The switch does not
have 10/100 Ethernet ports and 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.
Status LEDs The WX switches have LEDs that indicate port, power, and CPU status.
Table 4 lists the LEDs. (For the location of each LED, see Figure 1 and
Figure 2.)
