Fresh Setup ZBOX CI323 nano
-
Hey guys,
It's been a while. I finally found the time to set this up.
If this is the wrong section to post this please move it.
I put 250 Samsung SSD in it and 16gb ram, it came with wifi card but pFsense does not pick it up. Not that it matters to me.
Excuse the cabling mess, it's just a quick work.
Setup is ADSL2+ Modem > pfSense box(Zotac c323) > Switch (TL-SG2210P) < (Wifi AP) < ethernet clients.
Everything is working great with the exception of one thing i cannot figure out..
When i connect my main desktop computer, the switch goes nuts. Shuts it's self off and ac power led on adapter goes into blinking mode. I've tried numerous different cables, ports and it only happens with this desktop. Those same cables work with other desktops.
Luckily i have a WiFi on this motherboard.

Maybe I'm stupid and missed something obvious but if anyone can help me that would be great.

Anyone any idea why the switch shuts off and AC power adapter LED starts blinking when i hook it up to hero alpha motherboard?

Do you have a DVM? Put a probe on the switch chassis (exposed metal) and one on the PC chassis (exposed metal) and put your meter on AC volts. Careful, since I suspect one of them is leaking significant voltage to ground (earth)
In theory, the cat5 spec says that all returns are supposed to be isolated from ground, but I'm betting that's not the case.

hey alphajim
thanks.
sadly no i don't have dvm or mm. bios has an option to turn off esd guard on nic port but it doesnt make difference. system has a custom loop watercooling in it i installed. everything is isolated from case as much possible etc. using silicone/rubber washers between motherboard and tray contacts. will try disconnected all cabling but the vga and nic, see if makes a diff.

Just an update for those wondering. Nothing worked, i pulled out all the cables, except for ethernet, tried different power points in house, different surge protectors. Updated firmware, turned off PoE. Nothing. When TL-SG2210P plugs into Intel i219-v it shuts itself off. For the moment the work around is i plugged the desktop into my WiFI AP ethernet port which is connected to TL-SG2210P. It Works. Should i contact tp-link about this or Asus?

Well i found out what the problem is from TP-Link forums
From one of their forum users
"We worked with TP-Link technical support and discovered that there is an issue that was only able to be resolved by removing the earth connector from the plug on the TP-Link power supply, and voila it works!"
and TP-Link response
"After the testing, we have confirmed the conjecture before, the NIC in the Asus motherboard does not isolate the MDI from the frame ground according to the IEEE802.3 requirement. As we said before the power adapter of the TL-SG2210P does not isolate as well and then the incompatible problem happens when they work together. The adapter of the TL-SG2210P and Asus motherboard are both to be blamed for this problem.
We are deeply sorry for that and we have already begin to apply new energy efficiency power adapter which will solve this problem perfectly. Thanks for your understanding in advance!"

Something to keep in mind if you're buying this switch and have these motherboards brand/gen.
I'm hoping TP-Link will issue a replacement for AC adapter soon.
