Hi. I am designing a new home network based on Unify. See diagram. Is this the best way to connect everthing?

The problem is: Core switch only has 2 x SFP10 ports so I cannot "star configure" both 24-port switches via SFP10 DAC cables.

Is it okay to daisy chain from the CORE switch --> Pro HD 24 PoE --> Pro HD 24 (as in diagram)? The alternative is "star configuration" (pink arrow) but I would have to use an Ethernet cable (not SFP DAC) from Pro HD 24 back to the Core switch. I heard this introduces latency compared to DAC. Which way is better?

The ProXG 10 POE out in garage will have to connect to the Core via 10G ethernet since its far away with CAT6 already in a buried conduit.

I can’t find a clear answer for best practice for network design for two questions.

1. Should all crestron NVX devices and Crestron Control devices (CP4, wired touchscreens , tsr310, Infinet gateway etc) share the same VLAN , or two different ?

I will be using Ubiquity Unifi and all these devices should share one level 3 switch (Pro XGS 24 port Poe). I would think they could share the same VLAN as the igmp multicast should prevent the control devices from being flooded, when properly configured ??

2. Cameras and 2N intercom. Unfortunately when using RAVA:Crestron for sip calling from 2N intercom, the 2N intercom has to be on the same subnet as your crestron touchscreens (ex 192.168.2.XX). I will have a bunch of IP cameras and NVR on their own VLAN. How can I get the 2N to stream continuous RTSP video stream to an NVR (VLAN 1) and still be able to do SIP calls to Crestron control tsw1060 touchscreen (VLAN2). Would I just have to create special firewall rules to allow the intercom to communicate to the camera vlan (that would otherwise be private/isolated).

What is the hardware difference between Crestron CP4R v1 (end of life) and V2?

Why does crestron home not update V1 based systems anymore ?

Will customers who invested $3000 in a CP4R V1 processor last year lose all future feature additions and bug fixes?

Currentl have Telus Fiber 1gbps service with the Intertek (Nokia) 4009203 white ONT box, and T3200M modem in bridge mode with my existing IT hardware. All of my legacy Optik boxes (which I want to keep- do not want the cloud versions) plug into the T3200. My home phone (x2 lines) plug into the ONT POTS1 and POTS2 ports.

I am renewing my term contract with 1.5 gbps service (same price). Apparently, I need two separate service visits: one to upgrade the internet, and when done, a second to upgrade the home phone to "fiber". They assured me my two land-lines (including a traditional fax) will still work. Apparently, two different appointments are required as the internet tech cannot do the home phone (which seems ridiculous/wrong?!).

3 questions:

1. Just wondering what hardware to expect? Will both the ONT and modem be replaced, and if so, with what devices?

2. Will the new modem still support bridge mode (I have my own router and harware setup).

3. Why does the home phone service need an "upgrade"? Right now there is RJ11 into the ONT POTS1/2- is this typical setup not supported with 1.5G service? What will change?

Thanks

In Edmonton. Just ran out on my 2 year residentail contract.

I have multi product - 1G internet fiber (happy with), 2 telephone land lines, Optik TV with almost every theme pack. Do NOT need mobile.

DM me for loyalty discussion. Happy with Telus and want to make this work for another 2 years.

Any suggestions for shops in Edmonton who will repair very small dings on your car doors , such as a 0.5 cm dent from someone’s car door dinging yours?
I heard there is paintless dent removal process that can fix this.

Anyone know if this can still be repaired without removing xpel matte paint protection film ? There is a small tear in mine where things dings occur.

Can someone help me troubleshoot why my core switch gets thousands of oversize frame errors per minute on my home network ?

The errors are only seen on 2 lan ports of my core network switch (in the port status page). These 2 ports are trunk ports for a VLAN that carries my Axis IP cameras (only).

The vlan for my cameras consists of Axis s2208 NVR appliance, which has a built in POE switch to which 4 cameras directly attach. The other 4 cameras are attached to a separate managed switch out in my garage (on the same VLAN carrier on a trunk port to the core switch).

The axis appliance actually has 2 lan port options - I am plugged into the port associated with the Poe switch. There is another lan port on the “motherboard” side of the nvr.

If I remove the axis nvr from my network, the oversize frame errors go away. However if I disable all the cameras on the nvr, the errors are still there.
Similarly if I turn off the garage switch (or all 4 cameras), the errors go away.

I tried setting the MTU on all switches to 9216 (from 1522 ) but it made no difference.

I suspect the axis nvr or my camera VLAN is the issue. What’s the best practice to set these up if you’re using a dedicated VLAN for all cameras?

I’m new to this and back into pc gaming. I have a 5080 and LG 39 gx950b which is amazing. Watched some of the YouTube HDR 8k + demos which are mind blowing (too bad hardly any are 21:9).

Any votes for what games showcase this monitor with a 5080 (I am okay using dlss) in terms of 2025-26 era AAA games , FPS or free world adventure type ?

Couple questions about loop flow rate / resistance :

1. Is it considered bad practice to have a 90’ fitting right at the outlet of your pump (in my case DDR 4.2)? I have heard the 90’ reduces flow when it’s right at pump and adds wear. But then I read that it takes like 30+ x 90’ fittings to significantly impede a loop! Is there a hydraulic reason why a 90’ fittings is bad right at the pump outlet, but not further along the loop?

2. Alphacool Core GPU block (5080). Is it normal to have flow drop on my ddc from 10L/min (when nothing connected to loop) to 4 L/min (when only the GPU block connected , not even a radiator )? Could my gpu block be obstructed, or is this degree of flow reduction normal ? For example , adding a single radiator by itself only drops flow from 10 to 6.5 L/min.
