The pocket size Ethernet switch can be placed on desk top or be mounted on the wall based on the needs of network 
environment.  First, connect copper or fiber cable from computers or network segments to the TX/FX ports on the units.  
Then assemble the power adaptor if necessary.  The supplied universal power adaptor comes with multiple connectors that 
can be deployed worldwide.  Depends on your power outlet, use either the original two prongs plug or select the 
appropriate adaptor to attach on the housing unit as shown in diagram 1 below.  Plug DC connector into the DC jack at the 
rear of the switch (figure 2), then attach AC connector into the power outlet.  Please be noted that as with any electronic 
device, you should place the switch where it will not be subject to extreme temperatures, humidity, or electromagnetic 
interference.
