The SMDC provides 4 dedicated and independent buses for user expansion. Many
devices including Northbridge, Southbridge, Super I/O, Hardware Monitor, LAN
controller, etc., provide I
2
C communication. These I
2
C buses bridge the proper
communication between these devices.
Teamed with other IPMB Devices (PMCs and EMCs)
Numerous devices in the market already support IPMB communication. BMC facilitates
the control and management of these devices. PMC stands for Peripheral
Management Controller and EMC stands for Enclosure Management Controller.
Depending on the overall set up of the system, the SMDC could initialize and
communicate with other PMC/EMC residing on the same IPMB bus. Simply connect
the devices to the designated IPMB connector. Available PMC/EMC options include:
• Satellite controller - SCSI RAID controller unit
• Power supply - power supply unit that has a hardware monitoring chip inside

Remote Console Redirect over LAN
Remote Console Redirection allows IT managers to effectively control and maneuver
text console of a remote machine. Serial console information goes through the
M3291/3295 SMDC and is processed over the network. TSO software then
reproduces the exact text console at a remote location. For example, someone may
own a group of servers at a remote location and could change options of those servers
from a completely separate location. Another example is that one may log in to the
Linux serial console through M3291/3295 SMDC over the network.
See SMDC installation section for details.
