The Oracle Fabric Interconnect uses only memory-free HCAs. Because of the way
Windows queries the HCA for firmware information, Windows can determine
whether the HCA card is mem-based or mem-free. As a result, the dual port HCA is
correctly displayed as MT25218 whenever the Device Manager is used to query the
HCA. For the firmware version, the value is the current revision level.
■ To check the firmware version, use the cat command as shown:
In this example, the MT25204 has firmware version 1.2.0 installed.
