Summary: I purchased this to replace an aging 3COm unmanaged switch, and this was out of the box, much better in quality, and once I powered up the HP JE009A#ABA V19110-48G, I noticed how much quieter this was compared to the 3COM.
Summary: The reviews a mixed on it because of the routing issues. I've used lots of the 10/100s at customers with no problems. This is the 10/100/1000 successor. Now I've experienced the problem first hand. I was switching out an old switch with this one during their break time. I pulled the old one and mounted this in its place and started it up.
Summary: Only the light indicator positions are not very well designed. When installed along with other routers/switches on the rack, they are hidden behind the patch cables and you have to dig in order to see their statuses. It fits better for a non-rack, small network.
Summary: Love these switches - we have deployed dozens of them at many clients. They are reliable, simple, inexpensive (compared to competition) and are well made. We used netgears - but they would fail. Cisco is great, but expensive. HP seems to be right on for the small to medium sized networks. They have all the right features, run cool, flexible configuration options.
