• Do network devices communicate when the LANMaster T8 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?
