2-4 CHAPTER 2: HARDWARE INSTALLATION

13Connect the power cables and turn on the power to the computer.

14Connect the 3C975 ATMLink NIC to the network.

The 3C975-F NIC uses 62.5/125 m multimode fiber-optic cable with SC duplex connectors. The 3C975-UTP NIC uses Category 5 unshielded twisted-pair cable with an RJ-45 connector. Both models are shown in Figure 2-3.

The physical installation of the ATMLink NIC is now complete.

It is strongly recommended that you run the ATMLink diagnostic utility before attempting to install the network drivers.The diagnostic utility verifies that the on-board components of each NIC function correctly.This utility also correlates the MAC address of the NIC with its PCI slot number. You must know the PCI slot number to load, configure, or reconfigure the Microsoft Windows NT network drivers.

The next step is to install the network software driver. For server driver installation procedures, refer to Chapter 3 for Windows NT, or to Chapter 4 for Novell NetWare.
