10.1 Error indication occurs in a protocol analysis session. Whether the error is a hard error indicated by a Beacon MAC frame or a soft error that indicates a possible NIC failure in the network peripheral, swap the respective NIC and rerun another thorough protocol analysis session on the ring. Some types of network peripherals have an NIC physically built in to the motherboard. If this is the case, then you may have to replace the whole unit. Reference the manufacturer's instructions. After you swapped the NIC and reran a protocol analysis session, did the error go away? Leave the newly replaced NIC in the network peripheral and record the problem in the network maintenance and service log. Return the original NIC back into the network peripheral; go to page 15 ; rerun a protocol analysis session on the ring. Sometimes, by rerunning a protocol analysis session, the failure cause becomes more clear by moving to another Token Ring address. If after rerunning a protocol analysis session the error does not move to another device and is still identifying the particular NIC address as a failure cause, troubleshoot the assigned lobe area for the respective NIC by going to page 2 . If after using this procedure you cannot conclusively locate the problem and continue to find failure symptoms that point to a network peripheral problem, reference the manufacturer's instructions.
