Straight-Through Twisted-Pair Cable for
10 Mbps or 100 Mbps Network Connections
Because of the HP Auto-MDIX operation of the 10/100 ports on the switches,
for all network connections, to PCs, servers or other end nodes, or to hubs or
other switches, you can use "straight-through" cables.
If any of these ports are given a fixed configuration, for example 100 Mbps/
Full Duplex, the ports operate as MDI-X ports, and straight-through cables
must be then used for connections to PC NICs and other MDI ports.
