I work for a company which is currently using a T1 line as their main network connection. They have just installed a metro ethernet line via AT&T. AT&T set up a white box which I'm guessing houses the modem and from there a pair of fiber cables come out and run into a cisco switch. I've tried using hyperterminal to get into the interface of the switch, but it looks like AT&T might have already set it up because it asks for a username and password which I do not have. My job is to reroute part of the building to use this new metro e line to free up bandwidth on the other T1 line. It looks like the first port on the switch is the only active/open one because when I try to plug an ethernet cable into any of the other ports, I get no response and no lights. However, when I plug an ethernet cable into the first working port and then into my laptop, the adapter says "connected", but it says limited or no network connectivity and thus, I am unable to get on the internet. I am here to ask for help as to what to do because I will need to get a connection working in order to reroute users. Do I need to add additional hardware? Configure other stuff? Does AT&T have additional work to do? Please help. Thanks in advance.
