Summary: No problems with this switch, works great. Love not having a fan and it doesn't get hot. The switch I replaced this one with had a fan, I didn't realize how annoying it was to have that fan running all the time until I hooked this one up. I have another switch with a fan in it, so I'm going to get another fanless D-Link and enjoy some additional reduced noise.
Summary: I bought this to go in a rack with other equipment. It serves the purpose in being able to connect all the computers in several racks using only one connection to the outside world. Especially liked the self seaking feature in that it makes no difference which port you use for upstream or downstream connections.
