I want to get into fiber optic fusion splicing, but all tutorials I can find use 99% isopropyl alcohol.
Due to my country's laws, I cannot get IPA over the counter. I can only buy denatured alcohol (ketonatus), and pure acetone.
What should I use to clean the gel from gel filled cable, and what should I use to clean the fiber before cleaving?
My brother has a gaming PC based on a gigabyte B550 GAMING X and a RYZEN 5600G.
He wants to upgrade to DDR5 soon, and won't need his mobo/ram anymore.
I also host minecraft servers for him, and due to me not being able to afford high end hardware, the servers do not have great single-thread performance.
He has decided to donate his mobo and ram to the server pool, but wants to keep his case.
I already have a PSU and boot SSD for the server, I only need a case.
The servers are sitting on a sturdy shelf in the garage, laying horizontally on top of each other.
I then need a case that is sturdy enough (doesn't have side glass) with enough airflow to not suffocate the machine.
The other two servers are old business machines, and the stack weighs about 15kg, and I think it would be better to stack them on the new case, as I don't trust the business machines' cases that much.
The only other requirement for the case is that it doesn't break the bank. If that means I am not allowed to stack on top of it, I can live with that. I still don't want breakable glass in a garage.
Thanks!
EDIT: Forgot to add, but the case ofc shouldn't have side fans nor extrusions in the side panel, as that would of course not stack.
Hello, currently I have a unifi USG-3P as my main router. Due to limitations I want to replace it with an opnsense box. Here is my current topology:
u/RepresentativeNeck63's current network topology
We have gigabit internet service. My provider provides internet on one vlan, phone service on another, and another IPTV vlan that I am not using right now.
As the USG-3P does not support multiple WAN vlans, nor ROAS vlan use, the ONT goes through a the smart switch to reach the router, and the voice vlan also splits off to go the server, which has a freePBX VPN that has a second virtual NIC on that vlan. (My provider doesn't want me doing this, but some european countries say you must let a user use their own equipment so I can do this teehee, though they do expect you to use an all-in-one box that has a builtin FXS unit that can directly be bound to that voice vlan, so this trickery is needed)
When getting the Opnsense box, I want to do this more logically. Do I connect the ONT directly to the Opnsense box? The box will have 4 ports, do I set up a LAG group to the smart switch? Do I also hook up the downstairs switch to the Opnsense box directly? (there is no L2 path needed to downstairs)
Some notes:
The smart switch supports VLANs and LAG groups, though no LACP. Most of the network is upstairs, and the downstairs switch supports VLANs though no LAG (though there are only two copper links downstairs, so unless the ONT goes back to switching trickery this is not possible anyway).
I am intending to run IPv6+IPv4 dual stack, and I am intending to run VLANs but am not right now. All devices that need vlan support (APs, Servers, etc) have a vlan capable path back to the router. The dumb switch sort of acts like a "wired access point" and all devices on it will be on one vlan.
Thanks in advance, kind strangers of reddit!
