    Can these be powered by PoE?

    Also, why not the 9-port switch for $34 instead? $5 cheaper & an express port for uplink. What other differences are there?

      10/100Mbps not Gigabit

      • Pretty sure this was the same question and answer on the last deal 😂

    • TL-SG1005P-PD is a 5 port switch powered by PoE, but don't believe TP-Link do an 8 port

  • Would being placed in the garage which regularly reaches temperatures in the mid 40's during summer be an issue?

    • Operating Temperature: 0–40 ℃

      Yes, it will be an issue according to the official specs.

      • -5

        I think it is unlikely that the device itself would be operating at above 40 degrees temporary or permanently…
        even if you can measure the current room temp as being above 40 degrees..

        also 40 degrees measured is max temp a room might get hot at
        but not sustained temp at 40 degrees
        unless their garage is a boiler room etc.

        • +2

          If the device is in a room that is above 40 degrees, why do you think the device would not also be above 40 degrees?

          They got an evap-cooler in there?

            @Joost:

            If the device is in a room that is above 40 degrees, why do you think the device would not also be above 40 degrees?

            1. the device is not a single block of material..
              Inside there is PCB board, chip, electronics components (like your PC which has different temperature of each pc part)
              and it is enclosed in a metal case which acts like a heatsink..
              which means the device may be lower temp internally than whatever the measure room temp is.

            Also if you look at things like real world example like cupboard is usually more cooler than the measured room temp..

            1. electronics usually have good tolerance for temps that might go above the stated operating temp as long it is not sustained temp.
              e.g. CPUs can reach above the max temp if it is not permanent

            2. 40 degree max temp is different to 40 degrees sustained temp
              As I said, this is not a sustain temp of 40 degrees for 24hrs a day unless the garage is a boiler room.

              enclosed in a metal case which acts like a heatsink..

              You've found the issue here. The electronic device is designed to move towards room temperature as quickly as possible. A cupboard is not.

                You've found the issue here. The electronic device is designed to move towards room temperature as quickly as possible. A cupboard is not.

                What issue? Didn't found anything..

                Also do you have proof that switch with the metal casing will reach room temperature of 40 degrees or above?
                e.g. essentially what you saying is if the room temperature is 45 degrees then electronic device / switch would reach a temp of 45 degrees quickly?

                OR
                would the metal enclosure dissipate the heat so that the switch would reach temp at operating temp of 0-40 degrees despite the room temp being above 40 degrees?

                Note: the room temp that is measured is not the same temp if you measured it at different location in the room..
                the temperature would be different if the thermometer was placed near the garage door, in the middle of the room

                Also where is the switch being placed, is it in a cupboard / cabinet.

                There a shit load of other factors which you didn't consider..

                And then

                1. we don't know what the actual temp is inside enclosed switch unless you got temperature sensor to tell us vs what the room temp is.
                  and even if you do the device is made of difference electronic components (which has tolerance for temp fluctuations)

                2. just for arguments sake and take your argument as being true, why you not address the other points I made?

                Is his garage gonna be at a sustain temperature above 40 degrees or just get that max temp of 40 degrees?
                ie is his garage is a boiler room?

                Many electronic devices and even electronic components (actual electronic parts on the PCB) has tolerances above that operating temp.
                This allows for the devices to function where there is spike temp outside of the operating temp.

                1. I highly doubt this switch would failed from experiencing low to mid 40 temps in his garage
                  which is not a sustained 40 degrees temp for 24 hrs… but just the max temp the day would reach for how many minutes ?
                • @pinkybrain: "e.g. essentially what you saying is if the room temperature is 45 degrees then electronic device / switch would reach a temp of 45 degrees quickly?"

                  Yes, it would reach a higher temperature than ambient.

                  "OR
                  would the metal enclosure dissipate the heat so that the switch would reach temp at operating temp of 0-40 degrees despite the room temp being above 40 degrees?"

                  Dissipate the heat by what means?
                  Metal does not have the property of magically being a lower temperature than its surrounding, it will actually reach the ambient temperature more quickly than most things as it has high thermal conductivity.

                  Heat is transferred from the device processor to the heat sink and enclosure, if the ambient temperature is higher, the heat cannot not radiate away.

                  Even with the device turned off it will reach ambient temperature. With it switched on it will reach the ambient temperature even faster because the device will be actively generating heat.

                  Say the device has a fan, and the ambient temperature is 45 degrees, the fan will only cause it to reach this temperature faster. To use your cupboard example here, if you put a hole in your cupboard with a fan blowing in air from the room, you'll find it will reach equilibrium with the room a lot faster

                    Was not even talking to you.. but
                    OK dude, you can continue arguing if you want..

                    the point of my original reply is in response to first concern

                    "Would being placed in the garage which regularly reaches temperatures in the mid 40's during summer be an issue?"

                    that the device should work fine even if it the room is over 40 degrees temp for x amount of hrs in summer
                    since this is max temp rather than a permanent temp of 40 degrees ie the garage is not a boiler room etc..

                    which is backed up by

                    iDroid comment

                    My garage is often over 40c for many many hours on a >30c day.
                    I have a 4 port one of these in there without issue. I also have an Asus router and my Starlink router in there - so far no problems (over 3 years in there now).

                    END OF DISCUSSION

                    • @pinkybrain: I agree, It likely would work fine as you suggest. They will define the operating temperature with less than ideal conditions in mind, like if the unit is in an enclosed space, and while supplying the full 62W budget to POE devices. There will likely be a healthy margin they include for users to avoid thermal shutdown.

                      I was refuting the idea that the device will somehow be at less than ambient temperature, it is generating heat and that simply can't be the case.

    • Would being placed in the garage which regularly reaches temperatures in the mid 40's during summer be an issue?

      what location is that where a garage regularly reaches mid 40s temp?

      • Thinking worst case scenario. Adelaide in summer. Thermometer reads low 40°'s on the hotter ones.

        Looking at a fttp upgrade, running conduit from outside box through the roofspace and mounting the internal box etc in the garage.

        Does this require a PoE injector? Looking at getting some cameras as well.

        • Thinking worst case scenario. Adelaide in summer. Thermometer reads low 40°'s on the hotter ones.

          if it stays 40 degrees permanently in that room then I think might be more an issue
          than it reaches a max 40 degrees.

          so you get low 40s in your garage
          how hot is it when you measured outside the house?

          Does this require a PoE injector? Looking at getting some cameras as well.

          don't know..
          what is the purpose of that?

          yeah the only reason why people get these POE is to connect cameras..

          what POE cameras you want to get?
          Are you connecting it to the switch and then to a PC or to an NVR?

          Do you need POE switch if we can connect it to NVR?

        • -1

          Does this require a PoE injector?

          It doesn't require a PoE injector. A PoE switch is basically like multiple PoE injectors glued together so its own power supply is way more powerful than a single PoE injector.

          If your FTTP NTD box is in the garage (which is quite common for a new build) then normally there would be another wiring from the garage (NBN) to a room where your router and most of the other network gears reside. That room generally is meant to be cooler and/or has air con.

          40°C is standard computer network equipment recommended operating temperature. The NBN FTTP NTD box's operating temperature recommendation is 0 to 40°C. The PoE switch will most likely work fine at a room temperature a few degrees above 40°C.

            The PoE switch will most likely work fine at a room temperature a few degrees above 40°C.

            also as I said
            the 40 degrees is not a permanent temp due to some internal heat source ie boiler room or heater
            this is max temp due the sun at the hottest time of the day during summer

            The device is not gonna failed because of ambient temp of low to mid 40 degrees for x amount of hrs in summers..

            • -1

              @pinkybrain: It's generally not a good place to place a PoE switch for cameras, unless you have a large garage with a dedicated workshop area. Server rooms generally have air con.

              $37.05 is no big deal, but if it is for cameras, it just doesn't make sense to power them from the garage.

    • worth a try.

      mount the switch vertically so the heat can escape the switch case, drill holes in the case for added ventilation

    • I doubt it. Operating it outside of recommended temperatures might shorten the lifespan a little bit but it's not going to blow up.

  • Do these suffer from security issues like wifi

    • Well if someone can physically access the ports, then yes it's an issue.

    • It's a layer 2 unmanaged (dumb) switch with no configurable options, all plug and play, no settings or logins to worry about, and no security issues other than the aforementioned physical access to the ports

    • It's an unmanaged switch. No such thing as a wifi on that, only physical ports for ethernet cables.

  • Amazon!!

    These TPLink "deals" most of the time cannot be supplied if you in the "wrong" warehouse area.
    This item cannot be shipped to your selected delivery location. Please choose a different delivery location.

    I'm in Vic, so guessing nothing in Melbourne, yet again.

    As for getting 40 degrees, yep I also get that in my large garage tin shed for many months of the year, often hitting 45 or more, so the gear in there is hotter than that.
    Stick with metal - with an inbuilt fan if you can and not cheap plastic units for those locations.

    These are dumb switches, so no not like wifi that may talk back to somewhere….

    • I'm in Melbourne and ordered yesterday, received today.

      • Melbourne delivery working for me.

    • Yep can very rarely buy these anymore. Really really sucks. So many items no longer eligible for delivery. I'm in NSW fwiw.

  • Can I use this to power my UniFi APs? Planning to set up 4 in my house

    • It depends on the particular AP you want to use.

      The TP-Link LS108GP switch has a max total power consumption of 62W for PoE.

      One U6+ AP has a max power consumption of 9W each.
      Four U6+ APs = 36W which is ok.

      One U7 Pro Indoor AP has a max power consumption of 21W each.
      Four U7 Pro Indoor APs = 84W which is too much.

      Four APs might not be necessary. Have you used the Unifi design centre tool?

      • +1

        Thanks Twix
        I’ll check out the design centre tool

        But otherwise, is there any other benefit to me having a UbiquitI POE switch between my router and the APs? Would rather save the few hundred $ if I can

        • +1

          Only if you want the layer 3 options of a ubiquti switch to use things like VLAN's or the ability to switch ports on/off or remotely reboot the AP's if they interface becomes unresponsive.

          If you're just after a simple setup, this would do the trick.

    • I use a similar TPLINK switch to power 2 Unifi APs so I can't see why not

    • Looked into this before and ended up using the lite 8 with 4x Poe.

  • What are these for?

    • +1

      It’s a device that lets you plug in multiple ethernet devices to your network. PoE (power over ethernet) means it can also power devices like security cameras or wifi access points.

  • Friends, does anyone have any suggestions for 16 port?

  • Thanks OP. Ordered one but had to change delivery to my sister's in Sydney because they don't deliver to rural NSW. I can wait though.

  • +1

    Thanks, bought one. Only need regular 8 port switch ATM, but for an extra $15 or so, good to have the POE in case I run security cameras in the future.
