    could this be for lightning protection?

    For the sake of the server, I hope that rest room is for staff only. I can imagine some 13 year old walking in and thinking it may be fun to drip water on the cabinet!

    Well in all fairness, the fiber bridge could be nescesarry if they had some seriously fubar'd ground loops in their network/power setup (Different parts of the network on different power systems with no proper grounding between the different types).

    In a case like that, then the optical link would act as a galvanic gap between the different parts.

    A setup like that, however would be highly dangerous to work with (high voltages on metal parts which should be grounded and most people do not suspect that the chassis of a computer is connected to the live wire on the power... )

    If that is the case, II would not enter that building without wearing large rubber gloves and similar boots etc. and I would not expect the building to be standing any longer as it would be a Disneyland for starting a fire....

    So it is likely just a clueless admin...

    I saw a fiber bridge just like that one time where they were going to split a network into two buildings. They set it up that way to split the network first for testing, then moved one bridge and subnet to the other building without incident.

    Aaah, the picture with the leaky roof in what looks suspicously like a former kitchen brought back memories... not exactly fond ones, though :-(

    No, that would be the 4 to 9 range - the 13 year olds would try to get access to the system for street cred in their hacking circles ;-)

    I've done the copper <-> fiber <-> copper one for lightning protection. Unfortunately, whoever did the one in the picture still fails as they almost certainly don't have enough separation for their power supplies.

  • SuperQ (unregistered) in reply to Marke
    Marke:
    could this be for lightning protection?

    Yup, the box behind it looks a lot like an outdoor wireless enclosure. Similar to stuff I've installed on rooftops before. Although normally you want a bit more separation for the lightning protection to work better.

  • anonymous (unregistered)

    We had a fiber bridge like that for lightning protection on a wireless link to another building. They do have a WTF with the power supplies in that pic.

    So if I understand your comment correctly, There is a serious problem, and rather than fix the problem, They chose to add new equipment to bandaid around the problem. Either way it fails.

    The "we put it like that to test it and are moving it to a different building" makes more sense, except it looks mounted a little more permanently than that.

  • PeterH (unregistered) in reply to frits

    Really, it looks like the right bump could topple the server, rip out whatever the yellow cable is plugged into and unplug the middle transformer brick.

    Stop a moment and take a good long look at that first picture. In fact, make it your wallpaper. That's because you need to understand that at least 99 out of 100 people would find nothing wrong with that.

    That's how much the average luser knows and cares about our precious IT systems. They expect it to be always on "like the electricity in the outlets" and to "just work" yet with no planning, care, design, maintenance, or cost.

    Yes, I hate it, and I'm sure you do to -- but I'm right and you know it.

    What's the solution? Educate the lusers? Isn't that our solution for every chair-keyboard-interface problem? And how has that been working out for you so far?

    So that the overcurrent would stop at the fiber rather than propagate through the wireless link, this that it?

    No worries then. Regular old copper Ethernet (10BaseT, 100BT, and so on) cannot have ground loops. Each node is inductively coupled to the network, so no DC gets through.

    It's actually because of the inductive coupling that PoE is possible. Any DC bias used to provide power is ignored by a standard Ethernet PHY.

  • Mike (unregistered)

    I've seen the fiber link used like this where a repeater was actually needed, but not immediately available. Usually not on 4-pair, though.

    It isn't right next to the sink, but we have the restroom/server room going on in my office. It is in the ladies' room, so it is funny seeing guys in there on the occasion they had to access the rack (almost worth the inconvience of walking to another restroom)

    Thats because HARDWARE needs to be SOLD to the PEOPLE with the MONEY, hence GOOD MARKETING is needed to drive the industry.

    I suspect the folks at the power company think that the expectation that the electricity from the outlets will "just work" is equally simple-minded.

    It wouldn't surprise me if that "Bridging the Gap" thing was security.

    Boss Joe: "We can't have the two networks directly connected together, someone might violate security over the interconnect cable."

    Serf Jack: (after carefully concealed inner sigh) "Ok. How about this. We'll put a fiber bridge in the middle. That will electrically isolate the networks and prevent security violations."

    Boss Joe: (cluelessly) "Great! That'll work."

    People who think they know a lot (but don't) can be both a hindrance and an advantage.

    ...or maybe, y'know, it was because "TrendNet" is clearly "trendy" (just ask the salesman).

  • Sergio Carlos (unregistered)

    On the Ethernet-Fiber bridges pic, it may have been used as a security measure in case there is a big electrical charge to stop the damage from propagating through wire. Seen those when connecting a long range antenna to the local network, in case lightning strikes the antenna

  • Jason (unregistered)

    Every time I see patch-cable spaghetti like that, I love the fact that I now work at a major telco.

    The folks that do the cabling are all ex-field installers, who have practically military parade precision on their cabling. Every one of the rooms I've looked in on has been clean and orderly, no snarls anywhere.

    That is indeed a very effective way of protecting a network, but plugging both units into the same circuit kind of defeats the purpose.

    If a product has to be "driven" that means people don't really want it. If they really wanted it, they'd go find it on their own. Marketdroids are the scum of the earth.

    It isn't that "no one" buys in, but that people who understand what they need and how it will benefit their business buy in, and the ignorant don't, which is the desirable condition. We are where we are today because the ignorant were pushed to "buy in" to something they didn't understand, and now that they have it, they don't realize why they should care to keep it working.

    So, nice troll, because as you see, I felt compelled to respond.

    ??? I don't understand. I go into the ladies' room to access racks all the time. Peer over the stall to charge up then upload a torrent to maintain anonymity. Full access to rack.

    Is the problem that you're doing something wrong, or that you don't know how to do it correctly?

    On a more serious note, I think the desirable condition is money in the bank. People who don't know any better often still have money and are even more easily convinced to give it to our employers. And then we get some. Without marketing, you might not have a job, either, as the market would be so crowded and HR still wouldn't be any good at picking candidates (as you likely consider yourself an exceptional candidate in reality, although maybe not ostensibly to a hiring manager). Would that be A Good Thing (TM)?

    Or, for me, it's monkey in the butt. Now that's a Good Thing (TantricMonkey).

    Don't bother calling me perverted. I get enough of that from my mom. While revisiting the first pussy I ever fucked. Only then it was with my whole body. OH YEAH!
