5.5.1.2 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.
Figure 10: MTUSB-1 with Cables
The MTUSB adapter comes with three cables, but has only two connections for cables. One cable
is an I2C cable with DB9 female connectors on both ends. One cable is a I2C cable with DB9
female connector to RJ45 male. Use the cable that matches your switch. The other is a USB cable
with one type A host connection to be connected to the server or PC and a type B connection to be
connected to the MTUSB adapter.
The I2C connector should only be used when the firmware cannot be updated in-band.
