Troubleshooting
1. Why can´t I share my Internet connection to multiple computers when using my D-Link DES-1108 switch?
If you are connecting directly to a Cable or DSL modem, you will need a router to “share” your Internet connection or
a computer using ICS (Internet Connection Sharing) or Proxy. Switches and hubs do not allow you to share a single
IP address to multiple computers.
Another alternative is to contact your ISP and purchase extra IP addresses for each additional computer.
2. Does the DES-1108 switch have an uplink port?
The DES-1108 has Auto-MDI ports which automatically sense the type of cable being used (e.g. Straight-through or
Crossover) and adjust themselves accordingly to pass data over the network.
3. What is the maximum length of Category 3, 4 or 5 twisted pair cable that can be used between the DES-1108
and other devices such as routers, switches, computers, etc.?
The maximum length of Category 3, 4 or 5 twisted pair cable that can be used between computers and other devices
on a network is 100 meters or about 328 feet. Keep in mind that this is a theoretical limit. Usually, you will want to keep
the distance between devices well below the limit.
4. What is Store-and-Forward switching?
Store-and-Forward switching will wait until the entire frame has arrived prior to forwarding it. This method stores the
entire frame in memory. Once the frame is in memory, the switch checks the destination address, source address,
and the CRC. If no errors are present, the frame is forwarded to the appropriate port. This process ensures that the
destination network is not affected by corrupted or truncated frames.
