AKING ETWORK
Note: Power over Ethernet connections work with all existing Category 3,
4, 5, 5e or 6 network cabling, including patch cables and
patch-panels, outlets, and other connecting hardware, without
requiring modification.
The SMC6824MPE switch delivers power to a device using the two unused
wire pairs in UTP or STP cable (RJ-45 pins 4, 5, 7, and 8). The switch can
provide up to 15.4 W of power continuously on each 10/100 Mbps port.
However, taking into account some power loss over the cable run, the
amount of power that can be delivered to a terminal device is 12.95 W. If a
device draws more than 15.4 W, from a port, an overload condition occurs
and the port turns off the power.
The switch controls the power and data on a port independently. Power can
be requested from a device that already has a data link to the switch. Also, the
switch can supply power to a device even if the port's data connection has
been disabled. The power on a port is continuously monitored by the switch
and it will be turned off as soon as a device connection is removed.

Cabling Guidelines

The RJ-45 ports on the SMC6824MPE switch support automatic MDI/
MDI-X pinout configuration, so you can use standard straight-through
twisted-pair cables to connect to any other network device (PCs, servers,
switches, routers, or hubs).
See Appendix B for further information on cabling.

ONNECTIONS
Do not plug a phone jack connector into an RJ-45 port. This will
damage the switch. Use only twisted-pair cables with RJ-45
connectors that conform to FCC standards.
