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 is required for direct attachment to Gigabit NICs or switches and routers through fiber
ports. Refer to
“Connecting a network device to a fiber port”
Automatic MDI or MDIX detection
All 10/100/1000 Copper ports on the
Dell
PowerConnect B-Series TI24X devices support
automatic Media Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX)
detection. This feature is enabled on all Gigabit copper ports by default. For each port, you can
disable auto MDI or MDIX, designate the port as an MDI port, or designate the port as an MDIX
port.
