# Attach the Network Cable

1. Connect a Twisted Pair Ethernet (TPE) network cable to the adapter.
   For 100BASE-TX, your network cable must be Category 5, twisted-pair wiring. If you plan to run the adapter at 100 Mbps, it must be connected to a 100BASE-TX hub or switch (not a 100BASE-T4 hub).

   For 10BASE-T, use Category 3, 4, or 5 twisted-pair wiring. If you want to use this adapter in a residential environment, you must use a Category 5 cable.

2. To configure the adapter, continue with the procedures specific to your operating system outlined later in this guide.

> NOTE: For dual port server adapters, you'll need a way to identify the Ethernet address for each port of the adapter. See Installing Multiple Adapters for more information.

## Fast Ethernet Wiring

The 100BASE-TX specification supports 100 Mbps transmission over two pairs of Category 5 twisted-pair Ethernet (TPE) wiring. One pair is for transmit operations and the other for receive operations. Segment lengths are limited to 100 meters with 100BASE-TX for signal timing reasons. This complies with the EIA 568 wiring standard.
