You need to issue a few commands via CLI!Is there anything we need to do after plugging in the breakout cable?
I think the original psu is also made by Delta. I inserted two Delta DPS-750XB-A in the switche and finally those power supplys can be recognized.After the SN2700 DC power supply is replaced with a Liteon AC power supply, Power Supply 1/2 is unresponsive. How can I read/modify the i2c/pmbus information of the power supply?
I've been wondering about this too, so I went poking... this looks interesting, but requires xxd:After the SN2700 DC power supply is replaced with a Liteon AC power supply, Power Supply 1/2 is unresponsive. How can I read/modify the i2c/pmbus information of the power supply?

If the password admin doesn't work you can reset the BIOS back to default without knowing the password by doing the followingAfter you have the above files, you will be able to replace the SSD on the device at will, but the non-original SSD will not make the SSD health report take effect.
Please also be careful not to try to use UEFI boot to install these on the SN2××× device, the system will think that the DMI information is incorrect, and then try to update the BIOS to restart continuously, although ONIE and the system itself support UEFI.
UEFI booting may be available on newer devices, but I haven't tried it.
The way to enter the BIOS settings is to press Ctrl+B during booting. If you are prompted to ask for a password, it may be admin.

why that specific ONIE version? this one Index of /onie looks to be version 2020.11-5.3.0005-115200Recovery ISO image used is ONIE v2019.11-5.2.0020 – 115200
That version seemed to let me operate at 115.2 baud from BIOS to web gui.why that specific ONIE version? this one Index of /onie looks to be version 2020.11-5.3.0005-115200

Looks like PSU fan speed control is available via PMBus: OpenNetworkLinux/driver-hwmon-pmbus-dni_dps460.patch at master · opencomputeproject/OpenNetworkLinuxI'm looking into where the firmware for the PSUs might live. It would be nice to pull it off of a legitimate Mellanox PSU and try flashing it on to a replacement OEM Delta PSU. That might address the fan speed issue referenced elsewhere in this thread.

Nope.I have an SB7700, I believe I need a license to get 100gb EDR instead of the 56gb FDR correct?
