EXPIRED Mellanox SX6036 36ports QSFP €150

Quick question for those that have this switch with ethernet enabled.
I have a 10 gbps SFP DAC connected via a QSA adapter and auto negotiate doesn't work. The switch pulls all of the information from the SFP and knows it's a 10gbps DAC but the link stays down until I manually change it to 10gbps (in web interface or cli). I have confirmed that the auto-negotiate checkbox is checked so I'm not sure if it's a limitation of the switch or something is wrong.

After 4 hours, I think I'm not really used to ltrace either... Could someone give me a hint? Thank you!
I have two SX6036G switches I bought second-hand, but they came with their old configurations and I can't get the old passwords. I have tried the fifteen-second reset button approach without success (looking at the console, it simply reboots the device). I have also tried to enter the boot manager but there is a password there as well, so I cannot initiate a reset via the console.
Is there any other approach I can take, either to flash a new OS with factory defaults or to forcibly reset the device? Happy to open the chassis and poke around if necessary. @cw823 any chance you can lend a helping hand?

I had experienced the same issue with SX6036F last month. For my case, it looks that 15 seconds were not enough.
After struggling for a couple of days, I could reset the admin password by pushing the reset button for a couple of minutes patiently.
I whooped with joy when I was able to login using xmladmin on the switch. Thank you @Veers! Very helpful.
I then put on a podcast, opened a tty console and held down the reset button. about three minutes later I saw in the console that the admin password reset was successful (see screenshot).
I continued to hold the button while the switch finished booting (another four minutes) and was able to sign into the admin account without a password prompt. Only then did I release the reset button, which prompted another restart. 7 minutes later I am able to login using admin, no password prompt.
I love this forum. Thanks again @kaz and @Veers for your quick responses! I've done a longer-form response with screenshots so the next poor soul can benefit.
Has anyone found a solution to the very slow response time / very high CPU utilization in newer OS versions? I'm thinking to revert back to 3.6.5009 or something to alleviate the problem, on 3.6.3004 my CPU utilization was 1-2%, on 3.6.8012 it is constantly 100% (tested more than 1 switch).
Edit: CPU utilization stays high for a long time after upgrading but gradually lowers to an average of ~20% on 3.6.8012 (vs. ~15% on 3.6.3004). The biggest difference comes from enabling ETH upon further inspection, with infiniband it is about 10% on recent versions, around 5% on 3.6.5000 or older.
Edit2: One of my switches responds much slower due to its CPU utilization being near 100%, even after being online for a couple of days..
Edit3: Problem resolved after another factory reset. I had reset prior to upgrading. (in CLI-> 'enable' -> 'config t' -> 'reset factory' -> 'YES')

Another seller got some switches. Not as low in price, but 213 euro is still pretty decent;

“It’s not a lie, if you believe it”You're aware that that is tax fraud, aren't you?
This thread has had a load of useful hints and information that has assisted me with both my EMC OS (now cross-flashed) SX6018 and my native MLNX-OS SX6036. If anyone comes across this and wanted bash CLI access and hasn't figured it out yet here's a guide.
First off get your switch flashed up to the latest version. We'll need to clear the U-Boot password and there's some minimum version required, apparently somewhere around 3.6.6003. Clear the U-Boot password per https://forums.servethehome.com/index.php?threads/mellanox-sx6012-help.9628/#post-192305.
Using the CLI or the web interface, create a new administrative user that will have bash CLI access. I suppose you could use the existing admin or xmladmin accounts, but I am making a dedicated account.
Next up we need to boot into the manufacturing OS using the files and instructions from https://forums.servethehome.com/ind...anox-sx6xxx-on-ebay.10786/page-42#post-287938 and https://forums.servethehome.com/ind...-as-mellanox-sx6xxx-on-ebay.10786/post-288220. I used a CentOS Linux VM for my TFTP server. All of my stuff was in /var/lib/tftpboot/mlnx460ex/.
A few environment variables need to be set to increase the ramdisk size and set the target TFTP server, 10.10.2.51 in my case.
Once in the manufacturing OS we can mount the OS areas, /dev/mtdblock6 and/or /dev/mtdblock7 as well as the config area, /dev/mtdblock8.
The manufacuring OS does have mddbreq, but it seems to be too old or something as it has issues.
Maybe using
While we're here, make a backup of the DB.
And also while we're here, we can take a look at the native MLNX-OS IB SM HA cluster shared secret. This has nothing to do with the license key shared secret. I'm pretty sure this is the same password I have on my luggage.
Check, change, and verify the new value of the shell for the admincli user.
Reboot the system and verify that you can get into the bash CLI. Here I'm just logging into the normal admin account first to make sure the system is fully booted.
Hope this of use to anyone wanting to tweak with their native MLNX-OS equipment. For example, mess with

Mar 7 07:07:58 (none) local7.debug mddbreq[1160]: [mddbreq.DEBUG]: Mddbreq exiting (exec time: 468 ms)--fix-bad-nodes would work for reading, but considering the chroot alternative works without issue I feel it's safer to just go that route. My 3.6.8012 image is on the second OS area, /dev/mtdblock7. I figure both should have a new enough version if you flashed through the supported version upgrade path. Adjust if there is a need to use the first OS area, /dev/mtdblock6.
