See “TestOptions” for descriptions.Test OptionsThere are two test options: the wrap test and the on-ringtest.The wrap test ensures that the PC Card and cablehardware are functioning properly. For this test, connectthe NIC and cable to the network to perform a wrap testthrough the hub or concentrator, or insert a wrap plug(no wrap plug is required if you have a shielded twistedpair 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 NICand the LAN. This test requires that the NIC is connectedto a network with other NICs, so the ring speed of thenetwork can be automatically sensed. If the NIC undertest is the only one on the network, the on-ring test willfail. Continue testing the NIC using the wrap test, orconnect the NIC to a network that has at least one otherstation connected and open.
