Adjusting Configuration Settings

Configuration for the 3C359 NIC is automatic for all operating systems. When you turn on the computer after installing the NIC, Plug and Play (PnP) automatically assigns all resources.

Table B-1 lists the default configuration settings of the 3C359 NIC at shipment.

Ring Speed

The 3C359 NIC operates at a ring speed of either

4 or 16 Mbps. The 3C359 NIC ring speed must match the speed of the token ring network. The default value is 16 Mbps.

The auto ring speed detection feature is enabled by default for all 3C359 NIC drivers. Auto ring speed detection overrides any manual setting of the ring speed through the 3C359 NIC configuration program. To disable auto ring speed detection and manually set the ring speed to either 16 Mbps or 4 Mbps, see “Selecting Ring Speed,” in Chapter 4.

It is recommended that you disable auto ring speed detection if you are installing the 3C359 NIC in a server. Otherwise, the server can fail to insert into the ring if it is the first station to come online and cannot detect a ring speed.
