I2C Interface RJ-45 Connector

There is an "I2C"interface on the front panel.
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.
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.
