Solving Ethernet Controller Problems; Solving Undetermined Problems - IBM System x iDataPlex dx360 M2 Problem Determination And Service Manual

1. Make sure that external SAS devices are turned on before you turn on the
2. Make sure that the cables for all external SAS devices are connected correctly.
3. Make sure that the SAS devices are configured correctly.

Solving 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:
v Make sure that the correct device drivers are installed and that they are at the
v Make sure that the Ethernet cable is installed correctly.
v Determine whether the hub supports auto-negotiation. If it does not, try
v Check the Ethernet controller LEDs on the system-board tray operator panel.
v Check the LAN activity LEDs on the system-board tray operator panel. The LAN
v Check for operating-system-specific causes of the problem.
v Make sure that the device drivers on the client and server are using the same
If the Ethernet controller still cannot connect to the network but the hardware
appears to be working, the network administrator must investigate other possible
causes of the error.

Solving undetermined problems

If the diagnostic tests did not diagnose the failure or if the system-board tray is
inoperative, use the information in this section.

latest level.
– 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 system-board trays (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.
configuring the integrated Ethernet controller manually to match the speed and
duplex mode of the hub.
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.
– The Ethernet transmit/receive activity LED is lit when the Ethernet controller
sends or receives data over the Ethernet network. If the Ethernet
transmit/receive activity light is off, make sure that the hub and network are
operating and that the correct device drivers are installed.
activity LEDs are lit when data is active on the Ethernet network. If the LAN
activity LEDs are off, make sure that the hub and network are operating and that
the correct device drivers are installed.
