Technical Product Specification

Intel® Server Boards S4600LH2/T2 TPS
Revision 2.0
44
The server system supports a management link between the BMC and a NIC port, the BMC FW supports
concurrent OOB LAN management sessions for the following combination:
• 2 on-board NIC ports
• 1 on-board NIC and the optional dedicated add-in management NIC
• 2 on-board NICs and the optional dedicated add-in management NIC
All NIC ports must be on different subnets for the above concurrent usage models.
MAC addresses are assigned for the management NICs from a pool of 2 MAC addresses specifically for
manageability. For these channels, support can be enabled for IPMI-over-LAN and DHCP.
The server board has five MAC addresses programmed at the factory. MAC addresses are assigned as
follows:
 NIC 1 MAC address (for OS usage)
 NIC 2 MAC address = NIC 1 MAC address + 1 (for OS usage)
 BMC LAN channel 1 MAC address = NIC1 MAC address + 2
 BMC LAN channel 2 MAC address = NIC1 MAC address + 3
 BMC LAN channel 3 (RMM) MAC address = NIC1 MAC address + 4
The printed MAC address on the server board and/or server system is assigned to NIC1 on the server board.
