Forgive me if I am wrong, but isn't that what the link and status lights on the patron's network device is for? I know what you mean though. I've seen a number of phone cords, crossover cables, and CAT 3 cables not work on our network. Aside from that, we got a catalog once for a 3com Intellijack switch NJ220 That appears to have the link and traffic indicators right on the ports. http://www.3com.com/products/en_US/detail.jsp?tab=features&pathtype=purc hase&sku=WEBBNCNJ220SYS -----Original Message----- From: MSU Network Administrators Group [mailto:[log in to unmask]] On Behalf Of Bosman, Don Sent: Wednesday, June 30, 2004 2:02 PM To: [log in to unmask] Subject: [MSUNAG] Wanted: Cat-5 jack with indicator light I've done a casual search and not found any. In the library we have a number of faculty and grad student carrels. They all have netlink connections. Occasionally a faculty member complains up and down the various chains of pass the complaint that the carrel connections are not working. We test them and invariably find the patron has a bad cable or has not registered their notebook or laptop with the DHCP server. We end up - mutely - on the receiving end of "well it worked from home so it must be your fault" arguments. So, I'm seeking Cat-5, or better, jacks with indicator lights showing when the connection is live. Has anyone seen such a thing? Thanks.
