Ethernet Support Guide for HP-UX 11i v3

A Cabling requirements
This appendix contains information about the cabling requirements for Ethernet cards.
A.1 Connectors
The connectors on HP’s Gigabit Ethernet and 10 Gigabit Ethernet cards adhere to appropriate
standards agreed upon by various standards bodies and are widely available. The 1000Base-SX
port is compatible with the IEEE 802.3z standard and uses SC or LC connectors. The 1000Base-T
port is compatible with the IEEE 802.3ab standard and uses an RJ-45 connector.
A.2 Cabling
Incorrectly wired or installed cabling is the most common cause of communications problems for
local area networks. HP recommends that you work with a qualified cable installer for assistance
in your cabling requirements. Table B-1 summarizes the cabling requirements for the 1000Base-SX
and 1000Base-T products.

A.2.1 Back-to-back connection
When running 1000Base-T back-to-back at either 10 or 100 Mbit/s, you must use a crossover
cable configuration. At 1000 Mbit/s, you can use either a crossover or straight-through cable.
