Connector Information

This section includes pin usage information for the RJ-45 twisted pair connector. Connectors on LAN adapters adhere to appropriate standards agreed upon by various standards bodies and are widely available.

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 unshielded twisted-pair cables you use with the HP-PB 10/100Base-TX card must comply with the IEEE 802.3u 100Base-TX standards in order to meet emissions requirements. These standards support cabling up to 100 meters only.

HP-PB 10/100Base-TX Card Twisted-Pair Connector

There is only one connector on the card that is used for either 10Base-T or 100Base-TX operation. The operating mode is determined by the setting of the hub or switch to which the card is connected.

Connector Pin Usage for 10-Mbit/s Twisted-Pair Connector

Use unshielded twisted-pair cables that comply with the IEEE 802.3 Type 10Base-T standard.
