EPYC Motherboard

EPYC Motherboard Questions

Setting up to access the BMC so I can see more stuff and maybe turn up the cpu cooler fan.

I keep getting an "unable to access" when I put in the static IP address for BMC into my Foxfire browser.

I just added the default gateway IP and still no luck.

What am I missing?

How did you set the BMC to a

How did you set the BMC to a static address?  Normally, you just let your router serve it a DHPC address.

What does the browser input box show?  Does it have a lock symbol? The BMC port is a http connection and most browsers default to https nowadays.  You will have to acknowledge the warning message and ovveride the connection and tell it to connect knowing it is http.

Are you using the default BMC passwords? Is your motherboard a California delivered board?  Check the box for the password key printed on the box.

Is the static IP that you

Is the static IP that you picked for the BMC on the same subnet as your normal network? Did you pick an IP address outside the range of DHCP of your router to avoid any IP conflicts? 
 

for example my home network is on 192.168.1.0. I have the DHCP range set from 1-99. So anything over 192.168.1.100 is my static range. 
 

But I haven’t gone to the trouble to pick a static IP for my BMCs. I just let it get whatever from DHCP and note what it got (I look it up by cross referencing the device MAC address with the ARP table in my router). The IP almost never changes. You can also see what IP it got by watching the display on the POST screen, it will be listed.

Thank you Keith.

The Firefox browser was defaulting the https://  so tried it with http://  still no luck but I completely missed the https://

I went back and "cleared" all the address stuff and eventually re-created the "no BMC" message appearing during boot. 

I believe that is because I am running the monitor through a GPU.

Previously when I was running with no gpus and using the MB video port it would display the BMC address.  Probably 192.168.0.10 

Neither the static address I set it to 192.168.0.49 nor the 192.168.0.10 appear to be working.

I have had trouble forcing the use with the MB gpu when I have discrete gpu's installed.  It display all the POST but then stops displaying after the operating system boots...

Mummble.

The box label does say "California" on it.  New Egg usually ships from California. There is no recognizable password on the label on the box.

You can set the static address under the Bios Server Management menu.

I see all of the BMC

I see all of the BMC messaging on my monitors connected through a discrete gpu just fine.

You normally should just let the BMC defaults be.  Though I toggled the boot without full BMC initialization to speed up the boot a bit.

I only mentioned the California bit because of its privacy laws.  Forced motherboard makers to not ship products with the standard admin:admin login to the BMC.

My EPYCD8-2T board I got from Newegg had a unique BMC password printed on the product label.

I had to use that password to log into the BMC and change it to my easier to remember password.

this doesn't matter. I get the POST screen and all my systems are hooked up through the GPU. which GPU (which slot on the MB) are you using to hook up to the monitor? did you change the default VGA slot in the BIOS?

but is your router at 192.168.0.1? if your router is at 192.168.1.1 for example, using the '0' subnet wont work.  

what is your DHCP range? very possible that 49 and 10 are already taken by another device on the network, which is why it wont work. you need to constrain the DHCP range to something smaller than the full domain [1-254]. then choose a static IP outside of that smaller range. for example, set DHCP to 1-99, and set use the static IP ending in .100 for your BMC address.

As Ian mentions, it shows the BMC IP address during boot.  Or you can simply login to your router management and see what IP address it handed out to your host BMC.

Then use that IP address as the URL in your browser to login into the BMC management web server screens.

The default gateway address on the EPYC and the 3950x (WiFi) are both showing 192.168.0.1

I haven't noticed a "default slot".  There is an internal/external setting.  And I THINK the internal GPU setting causes the operating system to fail to display after it displays the POST info.

I am going to check that next by forcing the internal GPU setting, shutting down the system, switching to the VGA jack on the MB and starting it up again.

Apparently I misremembered, it gets to the OS boot and stalls after cleaning the HDD.  The "Ubuntu OS" first displays with the rotating/spinner.  Then the spinner goes away.  And nothing happens.

Waited 2 minutes or so....

Since I am running on the KVM switch I plugged the Discrete gpu back in on another "button", reset the internal/external from internal to auto.  It promptly booted up (still with no BMC address/message).

The only other idea I have is to switch the bios to "external" and see if the screen displays the ALL the POST that I have been missing.  Then back to the missing BMC address hunt.

And that answers Ian's question about the GPU slot. I apparently haven't used "external" GPU in a very long time.  "auto" was "working" to select the external GPU.

The slot is set to "7" which apparently works once the POST gets to the do you want to jump into "setup" just like it does from "auto".  No early BMC messages like internal displays.

The GPU I am using is sitting in the slot next to the CPU. 

I need to go find a slot# listing.

I am presuming that is slot 7. 

Yup that is slot 7 from the manual.

I am going to scratch my head more on this tomorrow.  I need to get more of the U@H test I am running done (U@H website messages).
