Figure 27 shows a cat-5 crossover cable for 1000Base-T.
Note: The 802.3ab standard calls for automatic negotiation of the connection
between two 1000Base-T ports. Consequently, a crossover cable may not be
required; a straight-through cable may work as well.
Connecting to workstations, servers, or routers
Straight-through UTP cabling is required for direct UTP attachment to workstations,
servers, or routers using network interface cards (NICs).
Fiber cabling with LC connectors is required for direct attachment to Gigabit NICs or
switches and routers.
Note: The 802.3ab standard (automatic MDI/MDIX detection) calls for automatic
negotiation of the connection between two 1000Base-T ports. Therefore, a
crossover cable may not be required; a straight-through cable may work as
well. For more information about this feature, see the
Configuration Guide .
