3Com's 10/100 Switching... Wallplate

An anonymous reader wrote in to say "Tom's hardware has an exclusive review of the new 3Com Network Jack. This is a 4-port 10/100 switch that fits in a standard-sized wallplate." Alright, thats a good idea (he says while accidentally kicking the switch hidden under his desk). Having run more then my share of ethernet drops in the past, I gotta say I dig this idea.

    The wall-ports at my work each have 6 ethernet connections, one BNC, and two telephone jacks.
    6 you may ask? Well, since ethernet only uses four of the eight wires in the cat5 cable, so you can send two connections down one cable (and out one wall jack), although you need a splitter cable (easy to make) if you want to get the second connection out of it of course :)
    Then, all the ports are wired up via the walls to a central switchboard where you can use short pieces of cable to connect the network any way you like. It's brilliant :)

      No... It is just fine. I have a number of runs where I use two connections, also ones where I have the ethernet and telephone using the same wire, and there is no significant difference in performance. This was the INTENDED purpose of using 8 wire configuration [one ethernet+one line POTS]. In fact, you'll notice that ethernet uses wires 1,2,3,6? If you wire up the center wires correctly, you should be able to plug a standard 6 conductor phone in the RJ45 [a 4 conductor connection will fit, but may jiggle], and the middle two wires [4,5] will work just fine. Plus if some moron plugs in a phone to the wrong jack it won't harm the ethernet.

      Crosstalk in decent [Cat 5 and higher] cable is basically a non-issue. Since all the pairs are twisted, they have very good immunity to inductive interference [take a e-mag course]. Unless you do something stupid, like wrap it around your Tesla coil or something, it probably won't be a problem.

      The only reasonable argument against using two connections over one wire is if one wire goes bad [a kink or break in the line], you can switch to another pair.

A new tenant moved in, and wanted ethernet connectivity for 3 computers, but we had only run one drop to each office, and we weren't interested in running an additional 200' drop, especially with the 3" of workspace above the ceiling panels.

      In order to set them up (and have them pay for only one connection), we had to run the live wire out of the wall, into one computer that's running NAT, then from a second NIC in that computer to a hub, then two cables from the hub back into the wall jack, then running over to the second jack (in an adjacent room of the same suite).

      If we had had a hub/switch integrated into the walljack (and especially if it had NAT capability, *wink* *wink* 3com), this would have made the job one hell of a lot cleaner. I'd even consider replacing our current setup with this, if just to try the thing out.

    Other than that, I somewhat agree with you. If you're working with a cabling architecture that you want to be flexible enough to be able to do other things than plain old ethernet, it's probably not a good choice for you.

    But on the other hand, if you just need 4 network ports at a location, it could be very useful. It's one less box sitting around on or under your desk. And just because you have 4 devices that need network, doesn't mean they're computers. 1 computer, 1 networked printer, 1 wireless access point, and perhaps your cable modem/DSL/whatever. Yes, sure, there are other solutions to do this (like the Linksys cable/DSL router with a 4-port hub and a WAP that I have on my desk right now), but the point is that this is another option. And it might offer a certain kind of flexibility depending on the situation. I'd actually consider it to be more useful as a home device, rather than an office device. Though it would be nice if they had the ability to power it from behind the wall.

    So it's no use to you. Doesn't mean that it's no use to everyone.

    There would be substantial cost savings when you have to pull cable. Rather than pulling four cables along, you pull just one. Also, at your floor drop, you only have one cable there and you will only be using one port. In your situation, your 4 Cat5 ports at the cubicle are using 4 Cat5 ports at your drop.


    Call me crazy, but if you were going to be setting up a new area, this would be a pretty nifty item to have. You just pull one cable. Power over Ethernet (PoE) is not THAT expensive. You're talking in the ball park of $100 or so.


    I see this product as something for new installations, not to replace what you've already got. If what's already there works, why change it? Going with these network jacks adds all kinds of room to grow. You get PoE and VoIP, as well as a four-port switch in every cubicle. That sounds pretty tasty, doesn't it?


    I also don't know what you're talking about as far as using cable testing equipment and downtime. When's the last time you had a cable go bad? Or a switch? If all four of your devices go out - it's either the uplink from that jack (one cable) or the jack itself. Consider if you have four lines and one of those goes out. Is it the cable to the panel? Is it the cable from the panel to floor drop?

    But what happens when you have a single location that needs more Ethernet? That's the target market here. Instead of getting the premise wiring guys back on site to haul more cable, you just use this jack to fan-out more ports.

Then he has the mystical `gigabit switch port' row.

I don't have many 4 year old hubs that haven't either died or got some blown ports. Lots of lightning around here. Its especially hard on hubs and NICs because of the ground surge differential on close strikes.

    I see no indication of either the extra cost for powered ethernet devices or the electrical work to power the 3com devices.

    The traditional wiring is costed for the worst case, where 4 ports are really active. Needing 4 ports available everywhere is not the same as needing 4 ports active everywhere. I routinely run four times the copper that I will need and activate ports as needed.

    An even better comparison would have been to compare the 3com wall jack hub to a free standing hub. But then the 3com would not have looked so good.
