Amber Green Explanation and Action
On Off The adapter self-diagnostic tests failed or there is a problem with the adapter.
Action: Go to “Adapter Diagnostics” on page 4-5 to test the adapter.
Blinking Off The adapter is closed due to one of the following conditions:
¹
The adapter open failed.
¹
The adapter detected a wire fault.
¹
The adapter failed the auto-removal test.
Action: Perform the following procedures, as appropriate:
1. Perform “Solving an Adapter Communication Problem” on page 4-1.
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.
Action: Go to “Solving an Adapter Communication Problem” on page 4-1.

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 4-1 on
page 4-4, 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.
Adapter Diagnostics
Important
To avoid potentially erroneous results, you should always perform a power-on
reboot of your computer before running the diagnostics.
The LANAIDC and Diagnostics diskette must be created before you run the
following procedure. Point your Web browser to x:\web\essmain on the CD-ROM
where x is your CD-ROM drive. Select your adapter and click Downloads. Select
Diagnostics and LANAIDC. Copy the diagdisk.exe file and run it to create the
Diagnostics and LANAIDC diskette.
