4.1 Power-Over-Ethernet (PoE) Switch
The EM35x Development Kit contains a NETGEAR 8-port Power-over-Ethernet (PoE) switch that supplies power to a Debug Adapter
(ISA3) over a standard TIA/EIA-568 category 5 cable. The Debug Adapter (ISA3) can, in turn, supply power to an EM35x Breakout
Board and the Module that is mounted on it. Thus, you can place Breakout Boards wherever an Ethernet cable connection is available.
The dc operating power for data terminal units is fed through unused pairs 7/8 and 4/5. For more information about the NETGEAR
switch, see its online technical specifications.
The NETGEAR PoE Switch that is supplied in the EM35x Development Kit is certified by Silicon Labs. If you wish to use a different PoE
switch, consult Customer Support.
The US-to-Multinational AC Plug Power Adapter Kit, shown in the following figure, is a set of three power adapters for use with the
NETGEAR PoE Switch. These three interchangeable plugs are provided with various port configurations suitable for North America,
Europe, the United Kingdom, and Australia.

tor for connecting power via a USB cable to the USB port of the Debug Adapter (ISA3) or Breakout Board. Five interchangeable snap-in
