Lights-out management administrator
(Skip these settings unless your server is an Xserve with a lights-out management (LOM) port.)
Give the LOM interface its own IP address. Don’t use the same address that you assigned to built-in
Ethernet 1, even though it uses the same physical connector (port 1) on the back of the Xserve.
The LOM administrator account is not the same as the Mac OS X Server administrator account that
you configured earlier in the setup process, but you can use the same name and password if you
want to.
IPv6 settings
The server normally generates IPv6 address settings automatically. If necessary, you can turn off IPv6
addressing or specify the following settings manually:
 IPv6 address: An eight-part number generally written in the form
0000:0000:0000:0000:0000:0000:0000:0000.
 Router: The IPv6 address of the router for the server’s local network.
 Prefix length: The number of significant bits in the subnet mask that are used to identify the
network.
Ethernet settings
The server normally configures the Ethernet settings automatically. If your network has specific
requirements, you can specify the following settings manually. Incorrect Ethernet settings can affect
network performance or render a port unusable.
 Speed: Specifies the maximum number of bits per second that the Ethernet port can send or
receive. If your computer and the device you are connecting to support Gigabit Ethernet but the
Ethernet cable you are using does not, you may need to adjust the Ethernet speed. Alternatively,
you can purchase a cable that supports Gigabit Ethernet.
 Duplex: Determines whether input and output packets are transmitted at the same time (full-
duplex) or alternately (half-duplex).
 MTU: The largest packet the port will send or receive. (MTU stands for maximum transmission
unit, expressed in bytes.) Increasing the packet size improves throughput (for example, for file
transfers), but the devices that receive the packet (switches, routers, and so forth) must support
the packet size.
