Table 6 lists LED states that indicate problems.
Table 6. Problems shown by adapter LED states
Amber Green Explanation Action
On Off The adapter self-diagnostic tests failed or
there is a problem with the adapter. Go to “Running adapter diagnostics” on
page 42 to test the adapter.
Blinking Off The adapter is closed due to one of the
following conditions:
v The adapter open failed.
v The adapter detected a wire fault.
v The adapter failed the auto-removal test.
Perform the following procedures, as
appropriate:
1. Go to “Solving an adapter communication
problem” on page 46.
2. Verify that the adapter is configured
correctly.
3. If other stations on the network are
having problems communicating, contact
your network administrator.
Blinking On The adapter has detected beaconing or a
hard error. Go to “Solving an adapter communication
problem” on page 46
On On The adapter has failed before running the
self-diagnostic tests. Go to “Running adapter diagnostics” on
page 42 to test the adapter.
See “Glossary” on page 97 for definitions of the terms used in Table 6.
Understanding the adapter labels
The green dot label indicates the speeds that this adapter supports over a token
ring.
The universally administered address label contains the adapter’s universally
administered address. This is the MAC address that was encoded in the adapter
memory at the factory. This 12-digit, hexadecimal address is recorded on the label
in groups of two digits from left to right, starting on the first row. In Figure 2 on
page 44, the universally administered address is X'00 06 2E 00 00 01' in
non-canonical format, with the most significant bit (MSB) first. The universally
administered address is unique and is used by network software to distinguish the
adapter from others in the network. If you prefer the adapter to be known on the
network by a locally administered address, you must configure the device driver or
protocol driver to use a locally administered address.
Solving problems with driver installation
If you have a problem with installing a driver, perform the following procedure.
1. Make sure that you correctly followed the instructions for installing the adapter.
2. In the following table, locate the row that describes the network operating
system or network application on the computer and perform the recommended
actions.
