■ For 100 Mbps connections to the ports, use Category 5 100-ohm differen-
tial UTP or STP cable only, as supported by the IEEE 802.3u 100Base-TX
standard.
■ For1000Mbps connections, Category5or better100-ohmdifferential UTP
or STP cable only, as supported by the IEEE 802.3ab 1000Base-T standard;
Category 5e or better is recommended.
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.
