HP 9000 Networking: Using PCI 10/100Base-TX/9000 > Appendix B Hardware Reference Information
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 same connector on the card 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. Use unshielded twisted-pair cables that comply with the IEEE 802.3 Type 10Base-T standard. Table B-1 IEEE 802.3 Type 10Base-T Standard
Available HP Cables:
Use Category 5 unshielded twisted-pair cables that comply with the IEEE 802.3u 100Base-TX standard. Table B-2 IEEE 802.3u 100Base-TX Standard
Available HP Cables:
Cable Lengths: The maximum length of the cable from the hub to each node for 100Base-TX is 100 meters. The cable must be category 5 UTP for 100Base-TX operation. For additional information on cable lengths and number of nodes supported by 10/100Base-TX, refer to the IEEE 802.3u Specification and Fast Ethernet, Dawn of a New Network by Howard W. Johnson (published 1996 by Prentice Hall PTR, Upper Saddle River, New Jersey 07458. Phone 800-382-3419. The ISBN number is 0-13-352643-7). |
