properly connected. Each computer must be connected from its
DFE-650TXD with a Category 5 cable. Examine the network
cables and ensure that they have not been damaged by having
been walked-on, rolled over by chairs, or closed in doors.
Additionally, make note of and alleviate any possible electromag-

Your network cables can be plugged into any port on your hub
except the "Uplink" port. The "Uplink" port is only used when con-
necting your hub to another hub or switch.
