How to reconnect a rack server to a UCS manager

[k.khussainov]

Hello everyone! I faced such problem, my rack server (UCS C 240 m4) was connected to UCS manager (3.1). At boot, Standalone mode was selected in the CIMC settings. After which I no longer see the server in the GUI (UCS manager) How can I reconnect the server to the manager? Is it enough to enter ip address in CIMC settings or do I need to choose other settings?

In the CIMC F8, config, do a reset to factory defaults.

This will force the CIMC to search for UCSM DHCP negotiation.

Also make sure you don't have any cables connected to the 1 Gb LOM or dedicated ports.

Thanks Kirk, I did a factory reset, but after rebooting the server still didn't connect to UCSM. I will attach a photo of the whole process. What am I doing wrong?

I noticed that after rebooting, the screen displays "error getting CIMC IP address"

I had to decommission the server and reconfirm. After that, the server will be successfully added to UCSM.
