Management and Firmware Updating Interfaces

The externally managed switch platform does not require any programming or configuration to
operate as a basic InfiniBand switch and includes all of the necessary functionality to operate with
external standard InfiniBand Subnet Management software such as OFED, FabricIT, UFM etc.
There is one interface to connect to the switch. It is an I2C RJ45 interface labelled "I2C". Use this
connector to update firmware (as a last resort) and for advanced debug.
4.5.1 RJ-45 Connector (I2C)
There is an "I2C" interface on the front panel.
