Changes:
- Updating externally-managed switch firmware (EMFW) has the unexpected side effect of disabling the ASIC firmware feature, which pushes thermal temperature information to the management FPGA controlling fans speeds. Normally, QSFP temperatures, internal ASIC die temperature, and external ASIC temperature are used to influence fan speeds. Due to this unexpected side effect, following an externally-managed switch firmware update, fan speeds will be purely a function of the external ASIC temperature sensor available to the management FPGA.
- Adaptive Routing does not adjust when eight virtual lanes (VL) are in use.
- If port beaconing is turn on and off for a QSFP port that has no QSFP inserted, or if the port is disabled by the FM or user, then the front panel LED will stay off when the port is re-enabled and a QSFP is inserted.
About Firmware Updates:
Applying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features.
On the other hand, downgrading the firmware version can recover the device's functionality in the event of a software update either turning up faulty or causing the unit's overall performance to drop. However, bear in mind that applying an older firmware isn't recommended and might not always be possible.
When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.
As the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update; regular users may initiate it at their own risk. Moreover, it's best that this task be performed in a steady power environment such as the one ensured by a UPS unit.
Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device's firmware. Also make sure you constantly check with our website to ensure that you don't miss a single new release.
