Unifi Switch 48 PoE - Fixing my power issues

- I was running out of PoE power in my office, so it was time to upgrade to the USW-48-POE switch.

This is pretty cool. I'm thinking about starting a home lab in the new year as I near completion of my master's degree - partially to run a Spark cluster for ML, partially for hosting containerized apps, and mostly just for playing with. Not sure I'll do PoE, but this is fun to look at. Also, back to liking your teaching style - good use of music, fast forward, annotations / overlays, mixture of face and screen, and links to other videos. Keep being you, my friend.
Awww thanks Matt. I love doing these videos too! Sounds like you have quite a plan for your lab. I would recommend getting PoE switches, as more and more devices can be powered by it.
@@LarsKlintTech baby steps. I'm first converting an old desktop into a server. A 4U rack chassis is coming next week, which will fit the graphics card as well as the ATX motherboard and give me plenty of room for drive bays.
@@MattEland Toddler steps?
Great video Lars, I love your videos! I use the TP-link TL-SG116E semi managed 16 port switch for my 60-90m3 flat in Tokyo. It doesn't have POE but it is cheap and fan less and supports vlans. I can't imagine ever needing 48 ports. That being sad this is an impressive device especially due to the fact that it is silent. Also in my opinion 1gigabit is probably going to be plenty for the foreseeable future. Hav en god dag nede i Australien!
Thanks Anders for the kind words. You absolutely should use what suits your location, and sounds like you have it covered for the moment.
And yes, it is a really impressive device. Now I just need 32 more things to connect to it 😏
Og i lige måde. Jeg har aldrig været i Japan, men det kommer nok.
Yey now you can add more stuff ! :-)
A LOT more stuff 😂
Jumbo frames are a networking feature that allows the transmission of larger-than-standard data packets over a network. Unlike regular frames, which have a maximum size (MTU) of 1500 bytes, jumbo frames can be as large as 9000 to 9216 bytes or more, depending on the hardware and configuration. The primary benefit of jumbo frames lies in their ability to reduce overhead and improve network efficiency, as larger data payloads can be sent in fewer frames, leading to lower CPU utilization and enhanced throughput. They are commonly used in data centers, storage area networks (SANs), and high-performance computing (HPC) environments to optimize data transfers and boost inter-node communication. However, to leverage jumbo frames effectively, all devices along the network path must support and be configured to use them.
Awesome, thanks for sharing 😊
Top video Lars!,
Nice to see how the Unifi port diagram looks & thanks for showing how to manage the port labels too, really useful, hoping to save up for a Unifi home lab at some point soon, running TP-Link for now (on a budget), though the Unifi defo wins over on the spec & usability.
(re rack size & space - had that more than once, some models of switches either change or have a compact or full size for PoE), can be dangerous to get a "bigger rack", I often put more things into it!
Haha, I am totally with you there Andrew. Now I _need_ to fill the rest of the ports 😂
The Unifi port manager is really handy. It makes it really easy to check what is connected where. You could also use the AR solution, which is kinda fun, but not as quick.
@@LarsKlintTech I learnt an important lesson a few years back re data centre regulations, processes & proceeduresl
The DC site manager, always asked for a pre site survey before any works, the list of any/all kit, power load & network connections etc, before an install was allowed, part of this was to ensure each rack if new or existing, had the physical space & power for the task, as if you overload a rack, it can trip out the power & head for the DC, plus physical space does not exactly always make sense vs what kit you think re install vs actual space/dimensions etc, the simple rule was more power focused, he had an overall requirement of his job to ensure each rack had the right load, for BCP & DR - not a common issue, though each rack had A&B power - primary & backup... an important lesson to remember I guess, each cable had to tagged & labelled at each end (network & power), might sound OCD... tho critical, he was a top guy though firm & fair, good chap to know, I learnt a lot), at the end, he'd check each rack from top to bottom, to make sure not one item was missed or cable added, he was ex military & really knew his stuff, kept all his rack mount nuts & screws in a Cadbury's roses choc box!
@@andrewmccallum5699 The labelling is crucial in some scenarios too, and luckily there are a lot of tools (like the AR mode in the network app) that can help in retrofitting them. I have learnt as I went along, so my later installs are way cleaner than the first ones. Thanks for sharing 😊
Ohhh a teaser for the next video 😁

ohhhh i saw that little flash at the end!

Like the Fight Club esk frame insert
Hahaha, I didn't think of that, but I'll take it! 😂
Nice
Great video! I find myself in pretty much the exact same situation as you did, and looking at the USW-Pro-48-POE to replace my USW-16-PoE. My only concern is noise level. I seem to have requirements around 40-50W on the POE, and was wondering how you found the switch's noise level at reasonable loads? I've read the "near silent cooling" marketing line is fairly misleading?
Hi Dom. Thanks for watching 😊 You are referencing the _pro_ 48 port, which isn't fanless, but has "silent cooling" whatever that means. I can't find an official dB measurement for it. The USW-48-POE _is_ fanless so essentially completely quiet. If it makes any noise I can't hear it over the HDD noise from my NVR.
I would have thought those SFP's would be 10Gb
Yeah, I kinda did too, but they are 1Gb.
There’s a pro variant which does, looks like this might be the standard with the 1G SFP. Still a great switch though!
@@gavlewis I suspect it is to keep it fanless somehow. Or just to give me an excuse to get the Pro....
Can this be used as a standalone switch? Or does it require other equipment to work?
You can use UniFi switches in any network, but it is highly recommended to have a UniFi network controller, such as a Dream Machine SE. This will give you access to all the features of the switch.
I'm also looking to buy something like this but I really would like some 2,5 gb ports and SFP+ to be future-proof...
The Pro version of the 24 and 48 PoE switches have 10Gb SFP+ ports, but to get 2.5Gb ports you have to get the Enterprise series of switches.
A video for the PTZ camera? 👀 That needs some power i think
I'd love to get my greasy little hands on that beauty 🤓
If I remeember corecly Jubo incrise MTU 1500 to even 9000 then packets sending packets ar bigger bot on bouth sites You mast set the same MTU snder - resiver to work corecly normaly You don't need that iff Your network is slower then 10G
Thanks mate. I definitely don't need it then with my network 😂
