6.5 TROUBLESHOOTING
This section lists several situations that could happen while using the FN10, and suggests appropriate action. Because every situation is potentially unique, the corrective actions suggested here should be considered as guidelines only.
6.5.1 FN10 Does Not Power Up
If your FN10 does not power up, check each one of the following:
•Make sure the power source is operational.
•Make sure the power cord is securely connected.
If the FN10 still does not power up, contact Cabletron Systems Technical Support. Refer to Section 1.2 for more information.
6.5.2 Connectivity Problems
•Check for LED abnormalities.
•Check port status using LCM.
•Check for loose port connections.
•Check to see if the number of carrier losses is increasing using LCM. This indicates that the connection is suspect.
•Check to see if the number of total collisions has dramatically increased using LCM.
