TESTING AND TROUBLESHOOTING
This section contains procedures to verify the cabling connecting the
TRMIM-10R to the token ring network and any attached stations. A
description of LANVIEW and its function in troubleshooting physical
layer network problems is also provided.
4.1 INSTALLATION CHECK-OUT
Perform the following steps to check-out the installation of the
TRMIM-10R:
1. Be sure that the token ring stations and the MMAC match the
AC power source (120 Vac or 240 Vac) and are powered on.
2. Trace the ring path through the network, to be sure that there
are no breaks in the ring and that it is free from logical design
errors. While tracing the ring:
a. Check each cable connection on the MIM.
b. Verify that the pinout for every connector is correct.
c.
Check the cable conductors for continuity. Cable testers are
available for this task.
d. Check each cable connection at patch panels and wall plates.
3. Check the network ring speed:
a. Check that the ring speed matches the station and cable
specifications mentioned in Chapter 2, Installation Re-
quirements/Specifications.
b. Verify all devices on the ring network are set to the same ring
speed. Check all MIMs and stations in the network.
4. Verify that the maximum number of stations and maximum cable
lengths for each station are not exceeded.
