Cable considerations:
• Either straight-through or crossover cable can be used.
• Shielded (STP) or unshielded (UTP) twisted-pair cable can be used.
• Pins 1 and 2, 3 and 6 are the two active pairs in an Ethernet network.
• RJ-45 Pin-out: Pin 1 = TD+, Pin 2 = TD-, Pin 3 = RD+, Pin 6 = RD-
• Use only dedicated wire pairs for the active pins; e.g., blue/white and
white/blue, orange/white and white/orange, etc.
• Do not use flat or silver satin wire.
