Cabling Requirements

Cabling Requirements

Connectors on LAN 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 a single duplex SC connector. The 1000Base-T port is

compatible with the IEEE 802.3ab standard and uses an RJ-45 connector.

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. The following tables summarize

cabling requirements:

Back-to-Back Connection

When running 1000Base-T back-to-back at either 10 or 100 Mbps, you must use a

crossover cable conﬁguration. At 1000 Mbps, you can use either a crossover or

straight-through cable.
