• Network switch

    From Stuart@21:1/5 to All on Fri Jun 19 16:11:26 2020
    Following a power outage yesterday, neither of my W7 computers would
    access the internet. The cause was eventually traced to a network switch
    that one of them was connected to, the XP-box connected to the same switch
    did not suffer from the same issue. (Note that I do not normally use the
    XP box on the net, it was just a brief test.)

    The affected switch is a TPLink TL-SG108E, which is a managed switch. To replace will cost £39.29. I see similar switches varying in price from
    £17.26 upwards (TP-Link LS1008). These are unmanaged switches but
    otherwise appear to be pretty much the same.

    Question. What is "Managed switch" and do I need one?

    This normally connects to:
    My XP box,
    My W7 box,
    My ARMX6
    A Lacie "Networkspace2" NAS
    An Epson WF-7515 Printer,
    My Kinetic, though this is currently "out of use" as it's space is
    occupied by my BBC Master

    All one line.

    I would say you do not need a managed switch for your use. But I do
    suggest you try and get a GB capable one

    I personally have a 24 port unmanaged switch GB supported one here from TP-Link. Works well.

    I have an 8-port gigabit switch from TPLink - a TL-SG1008D
    and it has served me well for over 2 years now.

    Dunno! The one I refer to above isn't "managed". It's as
    near to plug and go as you might wish.

    A managed switch is programmable which suggests that it's configuration
    could be corrupted by a power outage so would need to be reset and then connected to a PC for reconfiguring (see its instruction manual). It's
    possible that the configuration for just some of the 8 ports has changed
    so try plugging your devices into different ports to see if any of them
    work.

    HOWEVER according to the TP-Link website the TL-SG108E is unmanaged: https://www.tp-link.com/uk/business-networking/unmanaged-pro-switch/tl-sg108e/ so it looks like it is kaput and you will need a new one.

    I suspect not.

    I have a couple of TPLink TL-SF-1005D switches in different
    parts of the house. Only four ports, but only costs a few
    quid. One is daisy-chained off the router. I have had this
    for quite some time and I feel certain that I paid £4 or £5.
    The other I got when the three port powerline plug I had the
    backup machines plugged into died. Rather than spend £50 odd
    on a new powerline plug when I had a single socket one spare
    I found I could get by with a second SF-1005D, though I
    think I had to pay £7 this time.

    Simply plug in and they work.

    It's unlikely you would need a managed switch for your setup, but before replacing the current one, it might be worth trying a reset.

    According to the manual there is a reset button on the back of the switch
    or it can be done via the switches web interface.

    It's branded as an 'Easy Smart Switch'. A managed switch is typically something you'd use in a business, with lots of enterprise configuration features (Spanning Tree, a command interface etc). This switch isn't like that, it just has slightly more software than a barebones switch enabling
    basic features like VLANs and quality of service, with a web interface to control it. On the first version there was no web interface and you needed
    a Java app supplied for Windows (I think I got it to work on Mac, but it was
    a bit painful).

    That said, it is possible to get it confused - if you manage to mess up the VLAN configuration for example you might find ports can't talk to each other. So doing a reset (hold down the reset button for 5 seconds) could be worth a go.

    Thanks to everyone who responded. I have now ordered a TP-Link LS108G,
    £18.82 inclusive.

    I did try the reset button a couple of times, holding down till the LEDs
    went out and then came back on again but there was no change.

    Having removed it, I noticed on the underside an IP addrss 192.168.0.1,
    which happens to be the same address as my router. (How does that avoid conflicts then if I try to access the router through the switch?)

    I connected it directly to a computer and logged on. I got a page
    declaring it to be the switch but non of the clickable "links" did
    anything and subsequently I could not even get that page.

    It doesn't. That's why you need to configure one or the other to not be on 192.168.0.1.
