We just purchased this switch (50 ports) and hooked it up to our network.
We took out all connection from our excisting gigabit switch and connected them to the cisco.
About half of these came up fine and the others were showing down. We took the ones that were down and put them back into the other switch and everyhting was fine. Took them again into the cisco switch and no light and still shwoing they are down.
Also, few users complained that when they came back from lunch, their connection was down. We swtched them from the cisco to the old switch and they were up and running fine.
What might causing the cisco to act like this?
