2. Refers to the actual channel used to send the request.
6.10.1 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.
2. User 2 (“root”) always has the administrator privilege level.
3. All user passwords (including passwords for 1 and 2) may be modified.
4. User IDs 3-15 may be used freely, with the condition that user names are unique.
Therefore, no other users can be named “” (Null), “root,” or any other existing user
name.
6.10.2 IPMB Communication Interface
The IPMB communication interface used the 100 KB/s version of an I
2
C bus as its physical medium.
For more information on I
2
C specifications, see the I
2
C Bus and How to Use It. The IPMB
implementation in the BMC is compliant with the IPMB V1.0, REVISION 1.0.
The BMC IPMB slave address is 20h.
The BMC both sends and receives IPMB messages over the IPMB interface. Non-IPMB
messages received by means of the IPMB interface are discarded.
Messages sent by the BMC can either be originated by the BMC, such as initialization agent
operation, or by another source. One example is KCS-IPMB bridging.
