Are the fan power connectors properly connected to the server board?
Is the cable from the front panel board connected to the server board?
Are the power supply cables properly connected to the server board?
Are there any shorted wires caused by pinched cables or power connector plugs forced
into power connector sockets the wrong way?
Server Connection Problems
If you can't connect to a server, check the following:
Make sure the network cable is securely attached to the connector at the system back
panel. If the cable is attached but the problem persists, try a different cable.
Make sure the hub port is configured for the same duplex mode as the network controller.
Check with your LAN administrator about the correct networking software that needs to
be installed.
If you are directly connecting two servers (no hub), you will need a crossover cable (see
your hub documentation for more information on crossover cables).
Check the network controller LEDs that are visible through an opening at the system
back panel.
