Attaching RJ-45 equipped Power Macintosh G3 with Coaxial (10Base-2 or 10Base-5) Ethernet cabling.
DISCUSSION The Power Macintosh G3 computers have a 10Base-T RJ-45 for unshielded twisted pair (UTP) connector for Ethernet, however, a generic AAUI for attaching accessory transceivers for media types other than RJ-45 is no longer include. Here three ways to connect a Power Macintosh G3 computer's 10Base-T Ethernet to an existing coaxial Ethernet network:
2. Add a hub with a BNC coax expansion port. 3. Use a Media Adapter Transceiver (BNC/RJ-45, or coax/UTP) The first solution may be the lease expense solution, especially if only a single computer is involved. Some PCI cards are dual-media, featuring both 10Base-T and 10Base-2 (BNC) connectors. Dual-media cards are a good choice if your coax network cabling is migrating to 10Base-T cabling in the future. Some of these cards can auto-sense which media is in use, while others may use a jumper to select which port is active. Dayna, Farallon, and Sonic Systems have such cards for PCI-equipped Macintosh computers. The second solution can range in price from that of a card to a more expensive hub, and is especially good if multiple 10Base-T systems are to be connected to an existing 10Base-2 coaxial Ethernet network -- or growth is anticipated. The more expense hubs, and some of the less expensive ones, include a BNC connector to link multiple hubs to form a backbone. Such a hub plugged into an existing coaxial Ethernet network can support as many 10Base-T devices as it has ports. A small hub with four to eight ports is a great choice if a small workgroup, or an office with several Ethernet 10Base-T devices, needs to be added to a network where only a single coaxial drop is available. A basic 10Base-T hub should work properly, as long as it has the BNC expansion connector. Also there hubs available with AUI (DB-15 connectors) for attaching to 10Base-5 (thick) Ethernet. The third solution was once in widespread use. Media adapter transceivers have faded from popularity as Ethernet has standardized more on twisted pair media, even though include diagnostic LEDs can give more information than the LEDs on a card or a hub. These media adapters can join a single RJ-45 connection to coax, and can to join two entire networks or add a single node to an existing network. Belkin part number F5D303, Cabletron part number CTP100-T, and Black Box part number REM-LE612A are examples of media adapter transceivers. Similar parts are available from these and other vendors for attaching 10Base-T Ethernet to 10Base-5 Ethernet. |
