Intelligent Platform Management Bus (IPMB) functions on devices connected to IPMB connector might not be available on Intel® Server Board S1200BTL.
Intel has discovered a potential marginal timing issue on the Intelligent Platform Management Bus (IPMB) of the Intel® Server Board S1200BTL when connected with a third party management device. The issue observed exhibits the following symptom: BMC data reads of over 2 bytes from connected IPMB devices might fail to complete. Single or Two byte reads between BMC IPMB and third party management devices are not affected by this issue. The affected PBA of the server board is E98681-306. The Intel® Server Systems R1304BTLSFAN, R1304BTLSHBN, P4304BTLSFCN and P4304BTLSHCN server boards with PBA E98681-306 are also affected.
The issue has been root caused to a violation of the Intelligent Platform Management Interface (IPMI) and PM (Power Management) Bus specification on the IPMB and PM Bus ports.
