NVIDIA Mellanox MCX546A-BCAN SmartNIC Firmware 16.31.2006

Firmware which is added at the time of manufacturing, is used to run user programs on the device and can be thought of as the software that allows hardware to run. Embedded firmware is used to control the functions of various hardware devices and systems, much like a computer’s operating system (OS) controls the function of software applications. Firmware may be written into read-only memory (ROM), erasable programmable read-only memory (EPROM) or flash memory.

Important Notes:
- SR-IOV - Virtual Functions (VF) per Port - The maximum Virtual Functions (VF) per port is 127.
- It is recommended to enable the “above 4G decoding” BIOS setting for features that require large amount of PCIe resources. Such features are: SR-IOV with numerous VFs, PCIe Emulated Switch, and Large BAR Requests.
- Security Hardening Enhancements: This release contains important reliability improvements and security hardening enhancements. NVIDIA recommends upgrading your devices firmware to this release to improve the devices’ firmware security and reliability.
- When upgrading or changing the configuration on multi-host adapter cards, for the changes to take effect, PCIe restart must be simultaneously sent from both hosts (servers). To do so, perform the following: 1. Shut down the server with the auxiliary card. 2. Shut down the server with the primary card. 3. Bring back the server with the primary card. 4. Bring back the server with the auxiliary card.

Bug Fixes:

- Altered the GetInventory NC-SI command to not report leading 0xf in firmware version when it starts with 0.
- Fixed PCIe lane margining capability issues.
- Fixed an issue related to the sl2vl mad that caused a few msec hiccup in the transmission on an InfiniBand network when the SM sent the sl2vl mad to a node in the cluster.

About Wireless LAN Drivers:

Windows OSes usually apply a generic driver that allows systems to recognize the wireless component. However, in order to use all available features of this hardware, you must install the appropriate drivers.

Enabling the wireless card allows systems to read chipset information and manufacturer name, as well as connect to a network without using an Ethernet cable.

Updating the driver version can resolve different compatibility issues, fix related errors spotted throughout the product's usage, add support for new operating systems, improve transfer speed, as well as bring various other changes.

As for applying this release, the installation steps should not pose to much of a challenge since each producer intends to make the procedure as easy as possible: just download the package, run the setup, and follow the on-screen instructions.

Bear in mind that we do not recommend you install this release on OSes other than the specified ones even though other platforms might also be suitable. Also, when the update has finished, do perform a restart to ensure that all changes take effect properly.

Therefore, if you wish to apply this package, click the download button, and setup the wireless card on your system. Moreover, if you want to stay “updated one minute ago,” check with our website as often as possible.
