This is how to translate a hardware address to a physical location:
The command lscfg shows the hardware addresses of all hardware. For example, the following command will give you more detail on an individual device (e.g. ent1):
# lscfg -pvl ent1
ent1 U788C.001.AAC1535-P1-T2 2-Port 10/100/1000 Base-TX PCI-X Adapter
2-Port 10/100/1000 Base-TX PCI-X Adapter:
Network Address.............001125C5E831
ROM Level.(alterable).......DV0210
Hardware Location Code......U788C.001.AAC1535-P1-T2
PLATFORM SPECIFIC
Name: ethernet
Node: ethernet@1,1
Device Type: network
Physical Location: U788C.001.AAC1535-P1-T2
This ent1 device is an 'Internal Port'. If we check ent2 on the same box:
# lscfg -pvl ent2
ent2 U788C.001.AAC1535-P1-C13-T1 2-Port 10/100/1000 Base-TX PCI-X
2-Port 10/100/1000 Base-TX PCI-X Adapter:
Part Number.................03N5298
FRU Number..................03N5298
EC Level....................H138454
Brand.......................H0
Manufacture ID..............YL1021
Network Address.............001A64A8D516
ROM Level.(alterable).......DV0210
Hardware Location Code......U788C.001.AAC1535-P1-C13-T1
PLATFORM SPECIFIC
Name: ethernet
Node: ethernet@1
Device Type: network
Physical Location: U788C.001.AAC1535-P1-C13-T1
This is a device on a PCI I/O card.
For a physical address like U788C.001.AAC1535-P1-C13-T1:
U788C.001.AAC1535 - This part identifies the 'system unit/drawer'. If your system is made up of several drawers, then look on the front and match the ID to this section of the address. Now go round the back of the server.
P1 - This is the PCI bus number. You may only have one.
C13 - Card Slot C13. They are numbered on the back of the server.
T1 - This is port 1 of 2 that are on the card.
Your internal ports won't have the Card Slot numbers, just the T number, representing the port. This should be marked on the back of your server. E.g.: U788C.001.AAC1535-P1-T2 means unit U788C.001.AAC1535, PCI bus P1, port T2 and you should be able to see T2 printed on the back of the server.
