Fault Isolation
If two network devices fail to communicate through the 1004
Repeater, consider the following:
•
Are the LEDs described in the previous section functioning
properly?
•
Do network devices have Link Integrity enabled?
•
Do network devices communicate when the 1004
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?
•
Is the thinnet cable unbroken and properly connected?
•
Are network interface cards properly configured?
