TOPIC

    This article contains important information and specifications for the 10/100Base-T Ethernet card k option for Power Macintosh G3 computers.

DISCUSSION

    If your computer came with the 10/100Base-T Ethernet option, a 10/100Base-T Ethernet card is installed in one of your computer's PCI slots. You can connect a cable for a 10/100Base-T Ethernet network to this card.

    Note: The type of twisted-pair cable you use depends on whether you connect to 10Base-T or 100Base-T Ethernet. Category 5 twisted-pair cable must be used to connect to 100Base-T if you want to get the maximum speed from this connection.

    Checking the Status of a 10/100Base-T Network Connection

    If you connect your computer to a network using the 10/100 Fast Ethernet card, you can check the card's LED indicators to monitor network activity. There are four indicators:
    ACT (Activity) Blinks when the 10/100 Fast Ethernet card is active.
    COL (Collision) Glows when a network collision has occurred (a temporary condition that occurs when two computers on a network try to send date simultaneously).
    LNK (Link) Glows when a reliable 10 megabit (Mbit) or 100 Mbit network connection has been established.
    100Mb Glows when a reliable 100 Mbit link is established
