☐ “Software Problems and Solutions” on page 109

Troubleshooting Checklist

The following checklist provides recommended actions to resolve problems installing the Allied Telesis AT-2911 Series Gigabit Ethernet Network Adapters or running them in your system.

Note

Before opening the cabinet of your system for removing or inserting the adapter, review all precautions outlined under “Reviewing Safety Precautions” on page 30.

☐ Inspect all cables and connections. Verify that the cable connections between the adapter and the switch are attached properly. Make sure that the cable length and rating are compliant with the requirements listed in “Connecting the Network Cables” on page 39.
☐ Check the adapter installation by reviewing Chapter 2, “Installing the Hardware” on page 29.
☐ Make sure that the adapter board is properly seated in a PCIe slot. Check for specific hardware problems, such as obvious damage to board components or the PCIe edge connector.
☐ Check the configuration settings and change them if they are in conflict with another device.
☐ Make sure that your system is using the latest BIOS.
☐ Try inserting the adapter in another slot. If the new position works, the original slot in your system may be defective.
☐ Replace the adapter that is not working with one that is known to work properly. If the second adapter works in the slot where the first one failed, the original adapter is probably defective.
☐ Install the adapter in another functioning system and run the tests again. If the adapter passed the tests in the new system, the original system may be defective.
☐ Remove all other adapters from the system and run the tests again. If the adapter passes the tests, the other adapters may be causing contention.

Checking a Port LED on the Adapter

Each port has an LED that indicates the link status. The LED functions once the driver is installed and the cables are connected properly. The LED is lit solid if data traffic is present.

Before the port LED can provide troubleshooting information, the adapter must be connected to the network and the network driver for your particular operating system must be installed.

Before troubleshooting, verify the following:

☐ The adapter driver software has been installed.
☐ The adapter is connected to a network.
☐ The LED operates properly.

To check the LED status, see Table 1 on page 21.

Testing Network Connectivity

To test network connectivity for Windows, perform the following procedure:

Note

When using forced link speeds, make sure that both the adapter and the switch, or link partner are forced to the same speed. Or, make sure the adapter and the link partner are configured for Auto-Negotiation.

1. Start the DOS prompt.

See."Starting the DOS Diagnostic Utility" on page 105.

1. At the prompt, type ipconfig /all

2. Type ping from the command line, then press Enter.

The network connectivity information is displayed, as shown in Figure 61.

Windows Server 2003

This section lists known problems and solutions for Windows Server 2003.

Problem: IP address is configurable on a member of the team.

Solution: When a team is created, the TCP/IP properties for the adapters are unselected. Then you can select and configure TCP/IP properties of the adapters and configure an IP address manually.

Problem: When creating 64 VLANs, all virtual adapters show disconnected or one of the 64 VLANs shows disabled.

Solution: The maximum VLAN configurations are 63 tagged and one untagged VLAN ID 0. If 64 tagged VLANs are created, they are disconnected. A reboot is required and only 63 tagged VLANs show links, while a 64th is disabled.

Miscellaneous

The following are known miscellaneous problems and solutions:

Problem: When the bus on the system is operating at PCIe mode, the adapter performs at PCIe mode if it is added by the Hot Plug application.

Solution: When the system is booted up without an adapter, the bus operates at the lowest mode which is PCIe. This problem can be corrected by rebooting the system.

Problem: The adapter may not perform at optimal level when it is added by the Hot Plug application on some systems.

Solution: The system BIOS, in some systems, does not set the cache line size and the latency timer, after the adapter is added by the Hot Plug application. This problem can be corrected by rebooting the system.

This appendix explains how to clean fiber optic connectors and includes the following topics:

☐ “Overview” on page 118
☐ "Cleaning Fiber Optic Connectors Using a Cartridge-Type Cleaner" on page 119
☐ “Cleaning Fiber Optic Connector Using a Swab” on page 121

Overview

The fiber optic connector consists of a fiber optic plug and its adapter. The end of the fiber optic cable is held in the core of the ferrule in the plug. Light signals are transmitted through the core of the fiber. Even minor smudges or dirt on the end face of the fiber, completely invisible to the naked eye, can disrupt light transmission and lead to failure of the component or of the entire system. Therefore, it is of utmost importance to clean all fiber optic connectors before use.

Figure 62 shows the ferrule in an SC connector.
