10.2 A failure symptom appears to be directly related to a problem with a specific network peripheral. Is the network peripheral involved in some network communications with a particular application, or is it using the same directory or file on a particular file server when experiencing the symptom? Go to page 14 and troubleshoot a possible file server application or directory/file problem that may be related to the network peripheral operation. Move the network peripheral to another port on the MAU or wiring hub and recheck the network peripheral operation. Did moving the network peripheral to another port resolve the problem? Go to page 4 and troubleshoot a possible MAU or wiring hub problem. Troubleshoot the respective lobe cable involved by going to page 3 . If troubleshooting the lobe cable does not identify any problems with the lobe cable, come back to this page, using the "back" command in your browser as often as necessary, and proceed from here. Test the respective network peripheral for proper software and hardware configuration setup and requirements: If the network peripheral has local disk storage, make sure that all the necessary directories and files for the network peripheral are set up correctly. Make sure that all the necessary hardware is installed in the network peripheral and that it is configured correctly. Check the network operating system manuals for network peripheral setup concerning both software and hardware prerequisites. Did rechecking the network peripheral software and hardware requirements find any incorrect configuration-setup problems? Take the necessary action to resolve the configuration problem and retest the network peripheral device for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists, go to the next step . Attempt to run any available network peripheral diagnostics. Also try to troubleshoot the network peripheral for any I/O board conflicts. Did running the diagnostics or troubleshooting the network peripheral find any problems? Take the necessary action to resolve the problem and retest the network peripheral for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step . Continue. Has the NIC in the assigned network peripheral been troubleshot? A network file server-to-network peripheral related problem may exist as to ring insertion or protocol communication. Perform a protocol analysis session and focus closely on the communication between the network file server and the assigned network peripheral. Go to page 15. Go to page 5 and troubleshoot the respective network peripheral station for a NIC problem. Many network peripherals are being manufactured with internal NICs within the respective logic board hardware architecture. If the network peripheral you are troubleshooting has this configuration, attempt to replace the motherboard rather than going to 5 and troubleshooting the NIC. 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.
