Ethernet controller troubleshooting for the TS7650G (Gateway), ProtecTIER V3.4.3

Use the following troubleshooting guidelines to find solutions to 10/100/1000 Mbps Ethernet controller problems that have definite symptoms.

• Make sure that the correct device drivers are installed in the server and 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 or higher, you must use Category 5 cabling. For 1000 Mbps, use Category 5e or above.
  • 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 light-emitting diodes (LEDs) on the rear panel of the server. These LEDs indicate whether there is a problem with the connector, cable, or hub. See Figure 1.

  Table 1. Quad-port Ethernet LED indicators

  Number	Label	Indication	Meaning
  1 ,  3 ,  5 ,  7	ACT/LNK	Green on (not flashing)	The adapter is connected to a valid link partner.
  		Green on flashing	Data activity
  		Off	No link
  2 ,  4 ,  6 ,  8	10=OFF 100=GRN 1000=ORG	Off	10 Mbps
  		Green	100 Mbps
  		Orange	1000 Mbps
  		Orange flashing	Identity. Use the "Identify Adapter" button in Intel PROSet to control blinking. See Intel PROSet Help for more information.

  • 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.
• Check the local area network (LAN) activity LED on the rear of the server. The LAN activity LED is lit when data is active on the Ethernet network. If the LAN activity LED is off, make sure that the hub and network are operating and that the correct device drivers are installed.
• Check for operating-system-specific causes of the problem.
• Make sure that the device drivers on the client and server are using the same protocol.

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. If the Ethernet adapter is defective, see to Replacing a Dual-Port or Quad-Port Ethernet card and recovering Ethernet settings for the TS7650G (Gateway), ProtecTIER V3.4.3.
