Identify NEM and EM MAC Addresses
NEM Data Port MAC Addresses Assignment Per Blade
EM Data Port MAC Addresses Assignment Per Blade
All NEMs and EMs are shipped with unique MAC addresses for each port. The GbE NEM, for example, will have 20 unique port MAC addresses assigned – one for each RJ-45 data port. The starting MAC address for the 20 NEM ports is printed directly on the NEM board, for example:
If 00:14:4F:0C:B0:##-##
were printed on the NEM board
then the MAC address port range would be:
00:14:4F:nn:nn:## - 00:14:4F:nn:nn:##
where the first instance of 00:14:4F:nn:nn:##
= the unique starting port MAC addresss.
where the second instance of 00:14:4F:nn:nn:##
= the unique ending port MAC
addresss.
The GbE EM, for example, will have two unique port MAC addresses assigned – one for each RJ-45 data port. The MAC address for each EM port is printed on the EM board, for example:
00:14:4F:nn:nn:nn
where nn = the unique MAC address digits for each EM data port.
On the rear panel of a NEM there are two rows of RJ-45 data ports – one RJ-45 per network device interface. The RJ-45 data ports on the rear of a NEM are numbered top to bottom and right to left. Each RJ-45 data port corresponds to a blade. Each blade corresponds to two RJ-45 data ports, as shown in the following figure:
Illustration Key
Item |
Description |
---|---|
1 |
10 blades labeled BL0 to BL9 |
2 |
10 NEM RJ-45 ports labeled 0.0 to 9.0 |
3 |
10 NEM RJ-45 ports labeled 0.1 to 9.1 |
The NEM MAC addresses are hexadecimal numbers that are sequentially assigned to the NEM ports starting at the lowest port and ending at the highest port, for example:
If the starting and ending MAC address printed on a GbE NEM board were:
00:14:4F:0C:B0:20-33
where the NEM RJ-45 port is labeled 0.0, the MAC address for port 0.0 would be 00:14:4F:0C:B0:20
where the NEM RJ-45 port is labeled 0.1, the MAC address for port 0.1 would be 00:14:4F:0C:B0:21
where the NEM RJ-45 port is labeled 1.0, the MAC address for port 1.0 would be 00:14:4F:0C:B0:22
and so on until ...
where the NEM RJ-45 port is labeled 9.1, the MAC address for port 9.1 would be 00:14:4F:0C:B0:33
The physical NEM port MAC address will not change. However, the logical name assigned by an operating system (Solaris, Windows 2003 Server, or Linux) to a RJ-45 NEM port will be different from the physical MAC address. Information regarding how to configure multiple network interfaces (by their logical names) during an OS installation is provided in the following OS installation topics: Install Solaris From Local or Virtual Media.; Establish an SSH Connection to Configure the Factory-Installed Solaris 10 OS; Install RHEL4 via Local or Virtual Media; Install SLES9 via Local or Virtual Media;Install Windows Server 2003 From Local or Vitural Media
Each blade within a Sun Blade 8000 Chassis corresponds to two EM slots. On the rear panel of each EM there are two RJ-45 data ports – one RJ-45 per network device interface. Each RJ-45 data port corresponds to a blade. Each blade corresponds up to four RJ-45 EM data ports (two EMs per blade), as shown in the following figure:
The EM MAC addresses are sequentially assigned to the EM ports starting at the lowest port and ending at the highest port, for example:
If the port MAC addresses printed on a GbE EM were:
00:14:4F:C4:FC:33
and 00:14:4F:C4:FC:34
where the bottom EM RJ-45 port is labeled 0.0, the MAC address for port 0.0 would be 00:14:4F:C4:FC:33
where the top EM RJ-45 port is labeled 0.1, the MAC address for port 0.1 would be 00:14:4F:C4:FC:34
The physical EM port MAC address will not change. However, the logical name assigned by an operating system (Solaris, Windows 2003 Server, or Linux) to an RJ-45 EM port will be different from the physical MAC address.

Prior to installing a NEM or EM into the system chassis, you should have recorded the MAC address for each EM port and NEM port for future reference. For details about obtaining the MAC addresses printed on a NEM or EM board, see Install NEM and Install EM.
