Crossover Twisted-Pair Cable for
10 Mbps or 100 Mbps Network Connection
The HP Auto-MDIX operation of the 10/100 ports on the switch also allows
you to use crossover cables for all network connections, to PCs, servers or
other end nodes, or to hubs or other switches.
If any of these ports are given a fixed configuration, for example 100 Mbps/
Full Duplex, the ports operate as MDI-X ports, and crossover cables
must be
then used for connections to hubs or switches or other MDI-X network
devices.
