Mellanox Technologies

To list the available mst device names on the local machine, run ‘mst status’ (on Linux and Win-

dows only).

Notes for Windows:

The mst service, which provides PCI access to the target adapter, is run automatically

upon boot.

To access an adapter or switch device via the USB bus: A USB to I2C Adapter should

be used to connect the host USB port and the I2C port of the target device. Upon the

first usage of this interface, you will be requested to install the USB to I2C Adapter

driver (I2CBridge

Note for VMware ESX Server 3.5:

Only PCI user level access to Mellanox devices is supported on VMware ESX Server

3.5 machines. (See below.)

The format of an mst device name is as follows:

Via PCI: mt<dev-id>_pci<_crX|confX>

where:

X is the index of the adapter on the machine.

_crX devices access the adapter directly (recommended if possible)

confX devices use configuration cycles to access the adapter

For example:

Via USB to I2C adapter: For example, mtusb-1.

Via In-Band: <string>lid-<lid_number>.

For example:

The “mst ib add” command adds devices in the format:



for adapters and bridges:



for switches:
