Connecting the Network Cables
Copper
The Broadcom NetXtreme Gigabit Ethernet adapter has one or more RJ-45 connectors used for attaching the
system to an Ethernet copper-wire segment.
1. Select an appropriate cable. Table 1: “10/100/1000BASE-T Cable Specifications” lists the cable
requirements for connecting to 10/100/1000BASE-T ports:
2. Connect one end of the cable to the adapter.
3. Connect the other end of the cable to an RJ-45 Ethernet network port.
Note: The Broadcom NetXtreme Gigabit Ethernet adapter supports Automatic MDI Crossover (MDIX),
which eliminates the need for crossover cables when connecting machines back-to-back. A straight-
through Category 5 cable allows the machines to communicate when connected directly together.

1000BASE-T signaling requires four twisted pairs of Category 5 balanced cabling, as specified in ISO/IEC
11801:1995 and EIA/TIA-568-A (1995) and tested using procedures defined in TIA/EIA TSB95.

Category 5 is the minimum requirement. Category 5e and Category 6 are fully supported.
Note: After the cable is properly connected at both ends, the port LEDs on the adapter should be
functional. See Table 1: “10/100/1000BASE-T Cable Specifications,” on page 12 for a description of
network link and activity indications
