Test Options

There are two test options: the wrap test and the on-ring test.

The wrap test ensures that the PC Card and cable hardware are functioning properly. For this test, connect the NIC and cable to the network to perform a wrap test through the hub or concentrator, or insert a wrap plug (no wrap plug is required if you have a shielded twisted pair cable connection) to help isolate a failure to the NIC, the cable, or the wiring to the hub or concentrator.

The on-ring test verifies communication between the NIC and the LAN. This test requires that the NIC is connected to a network with other NICs, so the ring speed of the network can be automatically sensed. If the NIC under test is the only one on the network, the on-ring test will fail. Continue testing the NIC using the wrap test, or connect the NIC to a network that has at least one other station connected and open.
