IPMI over Keyboard Controller Style (KCS) Access

Use the information in this topic to control IPMI over Keyboard Controller Style (KCS) access to the XClarity Controller.

The XClarity Controller provides an IPMI interface via the KCS channel that does not require authentication.

Click Security under BMC Configuration to enable or disable IPMI over KCS Access.
Note
  • After you change the settings, you must restart the XClarity Controller for your changes to take effect.
  • Disabled (enable on demand) will disable the KCS channel most of the time, but allow some Lenovo tools to exchange information with the XClarity Controller during the system firmware update window. When that occurs, the KCS channel is enabled briefly for a few minutes and then disabled upon completion or upon timeout.
Important
If you are not running any tools or applications on the server that access the XClarity Controller through the IPMI protocol, it is highly recommended that you disable the IPMI KCS access for improved security. XClarity Essentials does use the IPMI over KCS interface to the XClarity Controller. If you disabled the IPMI over KCS interface, re-enable it prior to running XClarity Essentials on the server. Then disable the interface after you have finished.
