# Attach the Network Cable

## Network Adapter for RJ-45 Copper Connections

Insert the twisted pair, RJ-45 network cable as shown in the diagram.

| Type of cabling to use: For 1000BaseT (gigabit over copper), use Category 5 (must be 4-pair wiring). Make sure you use Category 5 cable that complies with the TIA-568 wiring specification. For 100BaseTX, use Category 5 wiring. For 10BaseT, use Category 3 or 5 wiring. If you want to use this adapter in a residential environment (at any speed), use Category 5 wiring. If the cable runs between rooms or through walls and/or ceilings, it should be plenum-rated for fire safety. In all cases: The adapter must be connected to a compatible link partner, preferably set to auto-negotiate speed and duplex. Intel(R) PRO/1000 Desktop Adapters using copper connections automatically accommodate either MDI or MDI-X connections. The auto-MDI-X feature of Intel PRO/1000 copper adapters allows you to directly connect two adapters without using a cross-over cable. For maximum cable lengths, see Adapter Specifications.

Proceed to driver installation.

## Network Adapter for Fiber SX Connections

Remove and save the fiber optic connector cover. Insert a 1000Base-SX duplex type SC fiber optic connector into the ports on the network adapter bracket, as shown in the illustration below.

| The connector and ports are keyed for proper orientation. If the cable you are using is not keyed, check to be sure the connector is oriented properly (transmit port connected to receive port on the link partner, and vice versa). The adapter must be connected to a compatible link partner, or an IEEE 802.3z-compliant gigabit switch. For maximum cable lengths, see Adapter Specifications.

| Caution. Always cover the adapter fiber optic connector with the provided cover or properly connect the adapter to a fiber optic communications cable. If an abnormal fault occurs, it could cause the Class 1 laser device to operate in a mode that may cause eye or skin damage if the adapter connectors are not covered.

Proceed to driver installation.
