1Installing and Connecting the NIC

Safety Precautions

Observe the following safety precautions.

WARNING: Computers operate with voltages that can be lethal. Before removing the cover, turn off the computer and unplug it. Disconnect all cables that are connected to the main system unit. Remove jewelry from your hands and wrists. Use insulated or nonconductive tools.

CAUTION: The NIC is packed in an antistatic container to protect it during shipment. Do not touch the components or any metal parts on the NIC, except for the backplate. To avoid damaging the NIC or the computer, reduce static electricity on your body by wearing an electrostatic discharge wrist strap attached to the chassis or by touching an unpainted metal part of the chassis before unplugging the computer and before handling the NIC.

CAUTION: Install the NIC in a PCI slot that conforms to PCI 2.2 specifications. Do not attempt to install the NIC in an ISA or EISA slot. Doing so may damage the NIC and the computer.

WARNING: Make sure that the computer power cord is unplugged. Only properly trained and authorized personnel should perform service. Contact the computer manufacturer for information about safe service techniques.
