Installing and Connecting an MP-372
21
Cat 5 cable with straight-through signaling must be installed at the site before you
install an MP access point. A single connection requires one cable. A dual-homed
connection requires two cables.
Table 3 lists the pin signals for 10/100 Ethernet straight-through wiring. Pins 4, 5,
7, and 8 are used when Trapeze Power over Ethernet (PoE) is enabled on the port.
RD means Receive Data and TD means Transmit Data.
Mounting an MP access point on a solid surface requires Cat 5 cable that does not
have strain relief. For installation on all other surfaces, you can use Cat 5 cable
with or without strain relief.
(For more information about cables, see “Cable Ports” on page 9.)
