Fault Isolation
If two network devices fail to communicate through the Token Ring
Multi-Media Repeater, consider the following:
•
Are the LEDs functioning properly?
•
Do network devices communicate when the Token Ring
Multi-Media Repeater is not installed between them?
•
Is flat or “silver satin” wire used in site internal wiring?
•
Are internal wiring patch cords, punch down blocks, and
wall jacks properly pinned or configured?
•
Are network interface cards properly configured?
