/dev/mst/SW_MT48438_lid-0x0003
Identify the switch you want to update according to its description or its LID.
in the examples below we will use SW_MT48438_lid-0x0003 as our target switch.
Query the switch to determine the current firmware version:
[root@mymach]> flint -d /dev/mst/SW_MT48438_lid-0x0003 q

4.3.2.2 Reprogramming the Switch Through The I2C Port
This interface is for Debug and Troubleshooting only. This interface is for FAEs and advanced
users only.
Use the MTUSB-1 adapter (available from Mellanox) to reprogram the switch firmware using a
server or PC running MFT.
The I2C connector should only be used when the firmware cannot be updated in-band.
