Symptom
With the Ethernet cable attached to the upper built-in Ethernet port, the Xserve G5 does not establish a network connection. For example, Startup Disk preferences shows no NetBoot volume.

Solution
Move the Ethernet cable from the upper built-in Ethernet port to the lower built-in Ethernet port.
The architecture of the Xserve G5 requires the lower Ethernet port to be connected to the network before the upper Ethernet port is used. This is not an issue if an optional Ethernet PCI card is used.
This symptom does not indicate an issue with the server and does not require hardware repair.
