Hello MikroTik Community,
I’m experiencing an issue with my MikroTik Cloud Router (CCR2116-12G-4S+) after a recent power outage. One of the power supply units (PSU2) has failed, and I’d like to get some advice on how to proceed. Below are the details of the issue:
Device Information
Model:
MikroTik Cloud Router CCR2116-12G-4S+
RouterOS Version: 7.18.1

Issue Description
After a power outage, the router rebooted unexpectedly. Upon checking the logs and system health, I noticed that PSU2 is in a FAIL state. Here’s what I observed

Questions for the Community
Is there a way to reset or restart PSU2 via software commands (PS Google says no!)?
I tried rebooting the router (/system reboot), but PSU2 remains in a FAIL state.
What are the recommended steps to replace PSU2?..
Additional Information
The router’s configuration was not affected by the outage, and all interfaces are functioning correctly after the reboot.
The logs do not show any other critical errors or warnings.
Commands Executed:
/system health print
/system reboot
I’d appreciate any advice or recommendations from the community on how to resolve this and prevent similar issues in the future.
Thank you in advance for your help!
