I recently bought a Dell R210ii with a iDRAC6 Enterprise card installed.
Everything seems to be fine except there is no mention of power monitoring on the iDRAC website, only voltage status. According to the user guide this server should have power monitoring functionality. iDRAC has been updated to latest version.
Running CLI commands for power monitoring also gives no meaningful data, output below.
