# Attach the Network Cable

1. Connect a Twisted Pair Ethernet (TPE) network cable to the adapter. For dual port server adapters, connect one or two cables 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 in Installing the Network Drivers. For dual port server adapters, read the notes in Installing Multiple Adapters.

> NOTE

> : Dual port adapters have two Ethernet addresses. The address for the first port (port A or 1) is printed on a label on the component side of the adapter. Add one to this address to obtain the value for the second port (port B or 2).

## 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.
