3 Unpack and inspect the NIC for damage.
4 Exit all open applications and user processes.
5 Turn off the power to the computer and attached
devices.
6 Unplug the power cables from the power source.
7 Remove the computer cover.
8 Locate an empty, nonshared bus-mastering PCI slot
and remove its slot cover. Save the screw, if there
is one.
Do not install the NIC in a shared PCI slot. Avoid any
PCI slot next to an ISA slot. This is often a shared slot and
does not support bus mastering.
If you do not know how to identify a PCI slot, check the
computer documentation or ask the system administrator.
If you are planning to install the Remote Wake-Up cable,
choose an empty PCI slot that is close to the matching
connector on the computer motherboard. The Remote
Wake-Up cable is only required if the computer complies
with PCI 2.1 and you want to use the Remote Wake-Up.
The cable is not required if the computer complies with
PCI 2.2.
