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.

Service (RIS)
Instructions
Problem: Microsoft Remote Installation Service (RIS) installation fails for
Windows XP.
Solution: Refer to Microsoft Article Q246184, “How to Add Third-Party
OEM Network Adapters to RIS Installations.”
Windows XP Image
To deploy a Windows XP Image, follow the steps in the Microsoft Article
Q246184 at http://support.microsoft.com/
default.aspx?scid=kb%3ben-us%3b246184.
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 propertie s for the ad apters
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.

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. There fore, it is of utmost importance to
clean all fiber optic connectors before use.
Figure 62 shows the ferrule in an SC connector.

Cleaning Fiber Optic Connectors Using a Cartridge-Type Cleaner
Fiber optic cartridge-type cleaners are available from many vendors and
typically called “cartridge cleaners.” See Figure 64.
Figure 64. Cartridge Cleaner
Note
Do not use compressed air or aerosol air to clean a fiber optic
connector.
To clean a fiber optic connector using a cartridge clea ner, do the following:
1. With one hand, hold the cartridge cleaner and push the lever on the
cleaning cartridge in the direction of the arrow to expose the cleaning
surface.
2. Place the ferrule tip on the exposed cleaning surface and rub the
ferrule in a downward direction, as shown in Figure 65.
Figure 65. Rubbing the Ferrule Tip on the Cleaning Surface
Appendix A: Cleaning Fiber Optic Connectors
120
Note
Rub the ferrule tip on the cleaning surface in one direction only.
3. When you reach the end of the cleaning surface, pick up the ferrule tip,
rotate and place it at the top and rub downwards at least 2 times.
Caution
Failing to pick up the ferrule tip when you reach the bottom of the
cleaning surface can result in static electricity that can damage the
fiber optic cable. E82
4. If desired, repeat steps 3 and 4.
5. If a fiber inspection scope is available, use the scope to inspect the
ferrule end face to make sure that it is clean.
6. Reconnect the cable to the port or protect the ferrule tip with a dust
cap.
Note
Always keep a dust cap on a fiber optic cable when it is not in use.
Note
Do not touch the end face of the ferrule in the connector.
Warning
Do not stare into the laser beam. L2
Warning
Do not look directly at the fiber optic cable ends or inspect the cable
ends with an optical lens. L6

Cleaning Fiber Optic Connector Using a Swab
Specially treated swabs (stick cleaners) are available for cleaning inside
connector adapters or hard-to-reach ferrule tips. These swabs, often
referred to as “lint free” or “alcohol free” swabs, are available from many
vendors. Stick cleaners are available in both 2.5 mm and 1.25 mm sizes
for use on SC and MU connectors respectively. See Figure 66.
Note
NEVER use a household cotton swab and/or a lcohol to clean a fibe r
optic connector. This may leave a residue on the ferrule tip.
Figure 66. Lint-Free and Alcohol-Free Swabs
Note
Do not use compressed air or aerosol air to clean a fiber optic
connector.
To clean a recessed ferrule using a swab, do the following.
1. Insert the swab into the adapter as shown in Figure 65 and rub the
ferrule tip with the swab.
