Internally Managed vs. Externally Managed
All internally managed switches can support IB fabric of up to 648 nodes. Internally managed
switches need an initial configuration before they will start working.
The externally (unmanaged) managed switch system is designed as a low cost switch and as a
result does not have any field replaceable units. This switch has no Ethernet or console inter-
faces. The only management interface is an I2C interface on the connector side.
Externally Managed (Unmanaged) switches are plug and play out of the box. Updating the firm-
ware stack for the externally managed switches is done in-band only. You will need to confirm
that your switch has the latest firmware. For externally managed switches, confirm that the latest
FW revision is installed on this device. Use the CLI to get the currently installed revision and
then go to Mellanox.com to check the revision of the latest version.
The following table shows which switches come with a management CPU and which do not.
