There is an “I2C”interface on the front panel.

Figure 4: I2C RJ-45 Interface

The I2C connection provides access to Flash and EEPROMs. The I2C connector is used to update firmware should in-band firmware update not work. You will need to order an RJ-45 to DB9 I2C adapter to make use of the I2C interface. You can order this adapter from Mellanox Technologies. The Ordering Part Number is MTUSB-1.

All firmware updates should be done in-band using Mellanox Firmware Management

Tools. This is for Advanced users and FAEs only.

These switches are Plug and Play and all firmware updates should be done in-band. The I2C con- nection should only be used if the FW image was corrupted to the point that the regular FW tools cannot successfully reburn the correct image.
