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 1005
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?
