Solved: S1200BTL BMC / RMM4 factory reset

CBoot1 · ‎06-17-2018

It seems that a long time ago I enabled LDAP authentication on my S1200BTL's BMC / RMM4. Clearly the LDAP setup I had then no longer resembles what I have now and I can no longer login to my BMC. How can I either disable LDAP authentication on the BMC or just completely factory reset it?

I've used the setup and ipmitool to change and enable built-in users but this doesn't let me in.

I've also tried to update the firmware with the "-setdef" flag but this doesn't appear to do what it claims.

Resetting the NVRAM doesn't affect the BMC.

Any guidance would be appreciated.

Hello bootc,

Thanks for joining the community.

So basically what you need is to factory reset the RMM4 settings, but neither clearing NVRAM or updating FW seems to do it. It is weird since it is supposed that even by doing a factory defaults on BIOS (F9) should clear the RMM4 setting.

In order to disable LDAP on BMC you will need to login into the RMM4 Web Console and go to the Configuration tab but in this case is useless since you cannot even log in. You can check this on the following URL: https://www.intel.com/content/dam/support/us/en/documents/motherboards/server/sb/intel_rmm4_bmc_ews_userguide_r2_8.pdf https://www.intel.com/content/dam/support/us/en/documents/motherboards/server/sb/intel_rmm4_bmc_ews_userguide_r2_8.pdf

Something else you can try is the force BMC update jumper to enable position (pins 2-3). For details go to https://www.intel.com/content/dam/support/us/en/documents/motherboards/server/sb/g13326007_s1200bt_tps_r2_4.pdf https://www.intel.com/content/dam/support/us/en/documents/motherboards/server/sb/g13326007_s1200bt_tps_r2_4.pdf# page=124

Hope this helps

Thanks for the quick response.

Resetting BIOS to defaults form the F2 setup screen didn't make any difference, but your post prompted me to try clearing CMOS using the jumper: that worked!

I didn't have to resort to the jumper, but for anyone else to stumbles across this it's jumper J4A2 ("BMC Force Update") which is at the top of the board by the LAN ports, marked "BMC FRU UPDT".

Thanks,

Chris
