Installation Requirements and Recommendations 27
The WX1200 supports 10/100 Ethernet connections. Table 8 lists the link
type and properties of the supported connections.
10/100 Ethernet Cable Wiring Connections on the 10/100 ports
require Category
5 (Cat 5) cable based on the EIA/TIA-586 standard. For
direct connection to a MAP access point, a router, or an end station such
as a PC, printer, or server, use a straight-through cable. For direct
connection to another switch, use a crossover cable. (The 10/100
Ethernet ports on the WX1200 switch provide automatic MDI/MDX,
which automatically crosses over the send and receive signals if required.)
Table 9 on page 28 lists the pin signals for 10/100 Ethernet
straight-through wiring. Pins 4, 5, 7, and 8 are used only when Power
over Ethernet (PoE) is enabled on the port. RD means Receive Data and
TD means Transmit Data.
