Note for chapter I/O Board
*1: Notes on LAN connection
LAN ports on the I/O Board and on LAN PCI Express cards belonging to the same partition have the same MAC
address by default. Therefore, do not connect them to the same subnet before you have changed the default MAC
address. You can assign unique MAC addresses to respective LAN ports by changing the OBP environment variable
“local-mac-address?” to “true”.
*2: DVD-ROM drive and the internal DAT drive cannot be connected to the expansion (second) I/O board of the SPARC®
ENTERPRISE M5000.
