Intel® Server Board S1200V3RP
Platform Management Functional Overview
Both Static and Dynamic CLTT modes implement a Hybrid Closed Loop Thermal Throttling
mechanism whereby the Integrated Memory Controller estimates the DRAM temperature in
between actual reads of the memory thermal sensors.

Messaging Interfaces
The BMC supports the following communications interfaces:
Host SMS interface by means of low pin count (LPC)/keyboard controller style (KCS)
interface
Host SMM interface by means of low pin count (LPC)/keyboard controller style (KCS)
interface
Intelligent Platform Management Bus (IPMB) I2C interface
LAN interface using the IPMI-over-LAN protocols
Every messaging interface is assigned an IPMI channel ID by IPMI 2.0. The following table
shows the standard channel assignments.

6.11.1
User Model
The BMC supports the IPMI 2.0 user model. 15 user IDs are supported. These 15 users can be
assigned to any channel. The following restrictions are placed on user-related operations:
1.
User names for User IDs 1 and 2 cannot be changed. These are always “” (Null/blank)
and “root” respectively.
