We have a Cisco C240 M3 v2 server which not auto starting up on power restore. I have been browsing through its BIOS looking for options like 'power on on power restore'. Our office building at the moment suffering from temporary frequent power outage. So, is there an option for auto powering up for Cisco C240 M3 v2 rack server?

Yes there is. In the far left column of CIMC, select the server tab. Select "Power Policy" from the items offered. The setting is called "Power Restore Policy" which you will want to set to either 'Restore Last State' or 'Power On' depending on your needs.

Here is a link to the relevant Cisco document - https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/sw/gui/config/guide/3_0/b_Cisco_UCS_C-series_GUI_Configuration_Guide_301/b_Cisco_UCS_C-series_GUI_Configuration_Guide_201_chapter_011.html#d71727e3886a1635

    @MD.MohiuddinAhmed - CIMC starts automatically when the machine is powered up. It is a system management chip separate from the BIOS. You can set the IP address for accessing CIMC by pushing F8 during the post process. community.cisco.com/t5/data-center-documents/…

    Here is the user guide for CIMC v2. I don't have a 2.0 machine around to check these out on, so I hope that this guide gets you to what you are looking for. There is also a command line interface for CIMC that you could use to input more directly - cisco.com/c/en/us/td/docs/unified_computing/ucs/c/sw/gui/config/…

    Yes, the CIMC chip runs both an HTTP service and a SSH service. The CIMC is accessed entirely separately from the operating system(s) that you install on the server. The basic idea is that you need to set a CIMC IP address (or DHCP) and then access that IP via a browser or SSH - cisco.com/c/en/us/td/docs/unified_computing/ucs/c/sw/cli/config/…

    Yes, you should be able to make that work. Or you attach the CIMC port to a switch and access it over the LAN.

    It should be, at least with proper settings (IP, gateway, etc.). The goal of the CIMC access port is just like any other Mgmt ethernet port on a device.
