Connecting the Network Cables
The Broadcom NetXtreme II adapter has either an RJ-45 connector used for attaching the system to an Ethernet copper-wire
segment or a fiber optic connector for attaching the system to an Ethernet fiber optic segment.
NOTE: This section does not apply to blade servers.
Copper Wire
NOTE: The Broadcom NetXtreme II 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.
1. Select an appropriate cable.
Table 1
lists the copper cable requirements for connecting to 10/100/1000BASE-T and
10GBASE-T ports:

1000BASE-T signaling requires four twisted pairs of Category 5 balanced cabling, as specified in ISO/IEC
11801:2002 and ANSI/EIA/TIA-568-B.
2
Category 5 is the minimum requirement. Category 5e and Category 6 are fully supported.
3
10GBASE-T signaling requires four twisted pairs of Category 6 or Category 6A (augmented Category 6) balanced
cabling, as specified in ISO/IEC 11801:2002 and ANSI/TIA/EIA-568-B.
2. Connect one end of the cable to the RJ-45 connector on the adapter.
3. Connect the other end of the cable to an RJ-45 Ethernet network port.
