TESTING AND TROUBLESHOOTING

b. Be sure that all devices in the ring network are set to the 

same ring speed. Check all MIMs and stations in the 
network.

c. Check that the MIMs in the MMAC are grouped together 

according to network type and data rate. For example, 
Ethernet MIMs together, 4 Mbit/s token ring MIMs 
together, and 16 Mbit/s token ring MIMs together.

4. Ensure that the maximum cable length for EACH station and 

the maximum number of stations are not exceeded.

When these checks have been successfully completed for each 
connection, the concentrator module is ready for normal operation. 
If further problems occur, contact Cabletron Systems Technical 
Support.

USING LANVIEW

LANVIEW is Cabletron Systems built-in visual diagnostic and 
status monitoring system. Using LANVIEW, your network 
troubleshooting personnel can quickly scan the LANVIEW LEDs to 
determine network status, diagnose network problems, and isolate 
faulty nodes or trunk segments.
