■

Registering the product

■

Installing the NIC in the PC

■

Connecting the NIC to the network

■

Installing the network driver

■

Enabling data encryption offloads (the 3C990B NIC is shipped with encryption 
offloading disabled)

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 2.1 or higher 
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.
