Configuration Record
Record the switch and jumper settings for your adapter in the following table. Later, you can refer to this
information whenever you run the diagnostics or replace the adapter.
Identifying Adapter Levels
There are two levels of the 8-port adapter. The two levels are functionally the same; however, the port
numbering of the port-selection jumpers and the arrangement of the communication-clock jumpers are
different.
You can identify the level of the adapter by the location of the option switches (see Figure 2-1 on
page 2-4). On the later level adapter, the option switches are located closer to the connector.
