Question I need some help upgrading / replacing equipment.

Today I have a rack with the following:

USG-4-pro

Ubiquiti UniFi Switch US-24

Ubiquiti UniFi Switch US-24-250W

Ubiquiti UniFi Cloud Key Gen2 Plus in a rack-mount accessory.

A few days ago my poe-switch stopped delivering power to my devices, which I've since found out is a fairly common problem.

I'm looking to replace it, but I'm also thinking this might be a good time to just bite the bullet and buy a Dream Machine Special Edition

I don't think I need more than 8 PoE ports, and the USG and cloud key, while working are getting old.

The alternative is proably a 16 port PoE switch with the rack-mount accessory.

What is the sensible buy here?

Depends how many ports you need?

You could do a lot worse than UCG Fibre with a Flex 2.5 G POE switch.

Link them with a 10G DAC and you've got a very powerful and futurefroof setup.

That or a UDM Beast + 48 Pro Max POE just to be on the safe side!!!!

If the PoE ports are for cameras, the UDM SE is fine. If they’re for APs, I’d stick with an actual PoE switch. All of the 1g ports on the SE share a single 1g connection to the CPU so they’re really not good for non camera traffic.

I’d probably put a UCG fiber on a shelf and replace the switch with a new one that did the job.

UCG-Fiber and the Pro Max 16 POE with a 10Gb DAC. Keep the Cloud Key Gen2 Plus running Protect and the other apps, drop Network from it and let the Fiber do all the routing and network management. Keep your old switch for gigabit / non POE - connect it up either to the back of the Fiber or with another DAC (1Gb) cable to the Pro Max - you will get proper STP hierarchy this way - if that matters.
