Cabling and Technology Information
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.
