Good evening,
how to solve this alarm for the fan speed changed to 60 % of the full speed.
any advies.
Hello mahmoudgad,
Can you provide some details:
What is the system model you are working with?
What error or failure you are seeing?
Was anything done recently like hardware or software changes?
What troubleshooting steps have you done already?
Are all fans running?
And a screen shots of the issue may help.
In general you need to make sure there is adequate cooling, all fans are running and nothing blocking air flow such as dust or papers or anything.

Hello @mahmoudgad,
Please, can you confirm the firmware version is updated?
I have seen this error in the past and the only way to fixing it was to replace the hardware after checking firmware was update.
Is the switch still in warranty?
Regards.

Hello Diego,
Thank you for your support, to confirm we need to upgrade to latest version to solve the above issue related to fan speed.
thanks for you advice.
Hello @mahmoudgad,
No. Sorry. In my previous message I said: "I have seen this error in the past and the only way to fixing it was to replace the hardware after checking firmware was update."
So I am just suggesting to update firmware and if the problem persist after the firmware upgrade, consider to have a hardware replacement.
Regards.
