Excerpt: The zyxel switch pays for itself in six months depending on your VOIP carrier and contract. Why rent equipment when you can own. This model will connect 7 phones to the internet and provide power for four of them (no need to have an AC outlet for your phone)easy to set up just plug and go.
Pros: Easy To Set Up, Easy to Use, Efficient, Reliable
Summary: For what it is, this is a really good switch. There seems to be some confusion about what this actually is though, and some of that is Newegg's fault for the misleading description, while others have only themselves to blame for not doing the research beforehand.
Pros: Others below have covered the overall features much better than I, but this is a really solid 4 port POE (+ 4 ports non-POE) switch. Never had any problems with it so far, and it's been powering several devices non-stop since it was first turned on 6 months ago or so.
Cons: Would have been nice for all the ports to be POE (or even better, POE+), and for gigabit support, but that'd be just wishful thinking for this price range.
Summary: The LAN sockets are now on the front of the unit, together with the indicator lights. The actual unit does not match Newegg's picture anymore (as of 12/26/12). Power cord and master power switch are on the back. There is also a 'IEEE802.3az ON/OFF' button on the front. This activates/deactivates the 'Energy Efficient Ethernet' function. Your POE device has to be compliant to use this feature.
Pros: Simple to setup, EEE compliant, lights and outlets on the front, documentation is well written, auto-negotiating, auto-crossover, 15.4 watts per port.
Cons: I am forced to enter something in the cons box but there are none.
Summary: For some reason when I read the description I thought it had 8 PoE ports but it doesn't, it is a 4x4 switch (4 powered and 4 non-powered). If you look at the pictures closely you can see it is a 4x4 switch but Newegg should try to be a little more clear in the descriptions on these small ticket items but then again a quick Google search would have likely given me that info too.
Pros: Bought this for testing IP phones at my desk, works perfectly. All I needed was an unmanaged switch that passes any tagged VLANs through which was just what I got. Plus it is quiet with no fan, and the power supply is internal so it doesn't take up a lot of power strip real estate! Rack mount tabs/screws, wall mount screws/anchors, and rubber feet all included. It is not tiny but not huge either, my USR modem that gets used two or three year sits on top nicely.
Cons: None, other than it has no Gigabit uplink port, but I knew that when I ordered it.
