last week, i bought a POE Extender because in our workplace, we only have one I/O Ethernet port in every cubicle. so in order for me to use a 2nd PC (we had plenty of spare PCs since we upgraded some of the 'not so old PCs') which is still good and didn't have any hardware or software problem.


i was very excited to received the POE Extender. however, when i connect a patch cord from the live I/O Ethernet port to the input of the POE Extender, it doesn't lit it's light (it has 2 small led lights). i was confuse as to why the led lights doesn't glow. i thought that i have connect the patch cord in the wrong port of the POE Extender so i connect it on any of the 4 ethernet ports but still all the led lights didn't blink.


then i was thinking maybe it only needs the output port connected to the PC in order for complete cycle of connection from I/O Ethernet port-POE Extender-PC but gush, still no such big or small thing happens.


what must be wrong? is there a tester for such device (or device test, if any)?


i bought the POE Extender since i don't like a device that has a charger because i don't like bulk of things underneath my cubicle.


now, i don't know what to do with this dumb thing as i'm just planning to buy an 8 port hub.
 
You didn't say whether or not you were supplying POE from your switch to begin with.

If not, then what you are looking for is a POE Injector, not a POE Extender.

Or, on my desk at work, I have a cute little 8 port switch that has 4 POE ports on it.


Just my $.02

... and I also have to ask why you need POE for a second PC? A PC doesn't run on POE...

An IP phone or camera may run on POE...

In order to connect multiple PCs to a singe Ethernet port, you can buy a simple, cheap, unmanaged switch.

thanks @gbaughma for the enlightenment [thumbsup2]


i just want to use the device to connect to another PC. i mean at the start of these thread, i stated that there is only 1 ethernet port in our cubicle. and since at the moment we have plenty of spare PCs at work, i get another PC for me to play on.


i just thought that a POE Extender will be just fine. any way, i already returned that device.


after, returning that device ... i bought this two (2) other devices which (hopefully) i think will work this time:

Passive Power over Ethernet PoE Adapter Injector

Ethernet Switch, Mini 5 Port Desktop Ethernet Network Switch (100Mbps LAN Hub/Small and Smart/Plug and Play)



will the Passive PoE Adapter Injector "B" function if it's inserted to Mini 5 Port Desktop Ethernet Network Switch?


thanks .. cheers!



P.S. thanks also @2ffat [thumbsup]

It's really going to depend on the switch. I would check with the manufacturer to verify.

Once again.... you do NOT need POE to simply attach another PC.

A PC doesn't run on POE.

All you need is a simple hub/switch.

I agree with everyone above, you DO NOT need POE. Nothing you mentioned required POE. You should NOT be getting anything with POE.

I have only one Ethernet port in my cube, but I have three devices in it. I have a simple four port HUB. It works perfectly.

 
well, i can say that i'm now more convince that i really need not a POE device.

so in view of this, may i know if this gadget (below) works just fine:

sg105_3_zpsrwn2eyzg.png



though the device is China-made but perhaps it's realiable and cheaper as well, that hoping this are all good for the spare PC that i have [wink]
 
That will work fine.
