perfect for those cold winter nights!
Not PoE+ so no autonegotiation. I’ll never fuck with passive poe switches again it is such a headache.
Do you really need 48 ports? That things gonna consume a lot of power even while idle.
What is the autonegociation you’re talking about here ? I never owned a POE switch, I, of course, don’t need all the port, it was the cheapest POE switch I could find near me, everything else is like 250€ or more, or 150 for unmanagable. It won’t be ON often for the moment, I just wanted a POE switch to have fun with wifi AP and in the futur IP cameras!
Autonegotiation allows two devices, such as switches or network interface cards, to automatically exchange information about their capabilities and configure the best possible connection settings, like speed and duplex mode. This enables devices to establish a link with optimal settings for both. Without it, this needs to be done manually
Not PoE+ so no autonegotiation
Yeah I already knew what autonego is, but this bit I didn’t understand, why POE/POE+ would affect auto nego ?
If I had to guess, negotiating POE voltage. Some stuff uses nonstandard voltage like some older ubiquiti gear
Oh, yeah okay, well, we’ll see if I encounter this issue!
That switch does it with CDP.
Auto negotiation is not an L2 process. It is a physical layer process that is performed before a CDP or LLDP packet can be transmitted.
He’s not talking about speed/duplex auto negotiation. He’s talking about automatic power negotiation.
Pretty sure it also supports lldp
I wrote a big thing about what I meant but this switch seems to have 802.11af so I may be wrong. Instead here’s a couple links to explain PoE better than I can

In this case the 3750G is a standards based PSE using 802.3af. It should not have any issues powering modern network equipment up to 15.4W
Yess! New community discovered! :)
What do you guys even use these big switches for?
I feel like I have a pretty comprehensive setup but I have 10 ports hooked up of my 12 port switch, 1 for every major room in the house(5), 2 for my office and 2 for the servers and one for input. And honestly I only use 2 room ones so I have 3 that go unused.
I can’t imagine the level of insanity that would require 48 ports for home use.
Those 3750Gs are beasts though! Fully L3 capable, and every feature you could possibly want in a switch from 2008. For my final project in college I actually used one of those as my core switch and pushed it to the max using it for redundancy, routing, etc. and it just shrugged as I was simply using it for what it was built for
They would use 10 ports, and have 38 port redundancy, lol.
No, the real reason would probably be to have like 20 security cameras.
lan party 🎉
Well… I have a few servers, that all have 2 port minimum (they actually all have 5 ethernets) (IPMI and Normal Ethernet) that’s already 10 port, plus my Desktop, plus the link nto the router, plus storage management of a JBOD (2 ports) that’s already 14 ports, and then I want to do stuff with POE Rasberry Pis (or similar) and I also have a few AP that I can now try and have fun with! I won’t use the 48 ports, but 24 ports were more expensives where I live… so, I took this one!
But why?
Homelabbing isn’t about WHY. It’s about WHY NOT. Why is so much of our homelabbing is overkill? Why not marry safe labbing if you love it so much. In fact, why not invent a special safety door that won’t hit you on the butt on the way out, because you are fired.
Lol but seriously though, what you hooking up to 48 ethernet ports? I can barely use 10
See my other comments ahah
That’s awesome! A great switch to use for a home lab and learn IOS.
Yes!! I have many switches! I see this is a Cisco, so you will learn how to run a managed network using Cisco CL. Making that work with the TPLink will be fun and educational. Pretty nice!
Now you can transfer files between computers without the need for an external storage device.
I’d say rip your ears but the G series is far quieter then the E series.
It is pretty quiet yeah, but not fanless I might try to mod it with some small noctua fans, won’t be optimal but it won’t run at 100% all the time, I’ll put the noisy blower back if one day I buy a enclosed rack
What’s a switch for so I can feel slightly more justified when i buy one?
OP can now connect 48 Ethernet devices. So like your desktop, and uh, a sip phone, and, uhhh the other 46 things on your desk that don’t have wifi.
If you find a $100 used server, that server will probably have 2-10 NICs on it. And any time you run a network cable, you should run 2 instead. And nobody wants to connect to a dead port. It all compounds. In a house 48 ports is kinda hard to use, but in a business with 10 people it is easy to fill a 48 port. It’s crazy how network cables multiply like rabbits.
Get two of them and a stack cable and you can have a 96 port switch.
