Michael,
Thanks....no blinky lights. I plugged into another network outlet, and the
network came up. Now for the spooky part.....
I have two cables (red, blue) and 2 network connections (A, B) in the wall
going back to the router/switch and 2 computers (D260, 1520).
A --red-->D260 = no blinky lights and no network connection
A --red-->1520 = blinky lights and network connection
B --blue-->D260 = blinky lights and network connection
B --blue-->1520 = blinky lights and network connection
I tried a third cable from A to D260 and got blinky lights and network. I
think there is something wrong with the red cable. Do you agree?
Mark
