Dynex DX-E401 User Manual

These precautions explain how to safely operate your new router, preventing 
injury to you or to others, or damage to the router.
Warning - read this carefully before proceeding.

• Do not open the router or attempt to disassemble or modify it.
• Do not insert fingers or foreign objects into the router.
• Do not expose the router to rain, use it near water or in damp or wet 

conditions, or place containers on it that contain liquids which might spill 
into openings.

• Follow  the  Installation Guide and this User Guide carefully. Follow the 

correct procedures when setting up the router.

A router is a device that forwards data packets from a source to a destination using 
IP addresses, not MAC addresses. A router forwards data from the Internet to a 
particular computer on your network.
The information that makes up the Internet gets moved around using routers. 
When you click on a link on a Web page, you send a request to a server to show 
you the next page. The information that is sent and received from your computer 
is moved from your computer to the server using routers. A router also determines 
the best route that your information should follow to ensure that the information 
is delivered correctly.
A router controls the amount of data that is sent through your network by 
eliminating information that should not be there. This provides security for the 
computers connected to your router, because computers from the outside cannot 
access or send information directly to any computer on your network. The router 
determines which computer the information should be forwarded to, then sends 
it. If the information is not intended for any computer on your network, the data is 
discarded. This keeps unwanted or harmful information from accessing or 
damaging your network.
