# Attach the Network Cable

## Network Adapter with RJ-45 Copper Connections

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

Type of cabling to use: For 1000BaseT (gigabit over copper), use Category 5 or better (must be 4-pair wiring). Make sure you use Category 5 cable that complies with the TIA-568 wiring specification. For more information on this specification, see the Telecommunications Industry Association's web site: www.tiaonline.org. For 100BaseTX, use Category 5 wiring or better. For 10BaseT, use Category 3 wiring or better.
| Caution: If using less than 4-pair cabling, you must manually configure the speed and duplex setting of the adapter and the link partner. In addition, with 2- and 3-pair cabling the adapter can only achieve speeds of up to 100Mbps.
If you want to use this adapter in a residential environment (at any speed), use Category 5 or better wiring. If the cable runs between rooms or through walls and/or ceilings, it should be plenum-rated for fire safety. In all cases: Length is limited to 100 meters. The adapter must be connected to a compatible link partner, preferably set to auto-negotiate speed and duplex. Intel® PRO/1000 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. | Single-port models Dual-port models

| NOTE: Dual port adapters have two Ethernet addresses. The address for the first port (port A or 1) is printed on a label on the component side of the adapter. Add one to this address to obtain the value for the second port (port B or 2).
