• Replace the identified component.
4. Reconnect all power cords and turn on the server. If the server starts successfully, replace the adapters
and devices one at a time until the problem is isolated.
5. Remove the adapters and disconnect the cables and power cords to all internal and external devices
until the server is at the minimum configuration that is required for the server to start (see "Server
controls, LEDs, and power" on page 16 for the minimum configuration.)
6. Reconnect all ac power cords and turn on the server. If the server starts successfully, reseat the
adapters and devices one at a time until the problem is isolated.
If the server does not start from the minimum configuration, see "Server controls, LEDs, and power" on page
16 to replace the components in the minimum configuration one at a time until the problem is isolated.

Solving Ethernet controller problems

Use this information to solve the Ethernet controller problems.
The method that you use to test the Ethernet controller depends on which operating system you are using.
See the operating-system documentation for information about Ethernet controllers, and see the Ethernet
controller device-driver readme file.
Try the following procedures:
• Make sure that the correct device drivers, which come with the server are installed and that they are at the
latest level.
• Make sure that the Ethernet cable is installed correctly.
– The cable must be securely attached at all connections. If the cable is attached but the problem
remains, try a different cable.
– If you set the Ethernet controller to operate at 100 Mbps, you must use Category 5 cabling.
– If you directly connect two servers (without a hub), or if you are not using a hub with X ports, use a
crossover cable. To determine whether a hub has an X port, check the port label. If the label contains
an X, the hub has an X port.
• Determine whether the hub supports auto-negotiation. If it does not, try configuring the integrated
Ethernet controller manually to match the speed and duplex mode of the hub.
• Check the Ethernet controller LEDs on the rear panel of the server. These LEDs indicate whether there is a
problem with the connector, cable, or hub.
– The Ethernet link status LED is lit when the Ethernet controller receives a link pulse from the hub. If the
LED is off, there might be a defective connector or cable or a problem with the hub.
