Summary: I bought one of these in 2012 when the power supply in my CISCO 24 Port unit died. I rack mounted the unit with the included ears and pluged it into my 4000 W UPS. I am using 12 active ports and have an additional 12 wired to wall jacks through my house. Its still in service.
Summary: I just plug this in about three weeks ago and it is running very well. Have no problems plugging in eight computers and of course the cable wire. I would recommend this for a small net set up.
