slot. Press the card firmly into the connector such that

3. Install the bracket screw that secures the card to the
computer chassis.
4. Replace the computer's chassis cover.
5. Reconnect the computer's power cord, and switch
computer power on. If the BIOS section of your
computer's boot program is Plug-and-Play compliant,
then at power-up the BIOS will automatically configure
any newly installed DGE-550T adapter.
  Due to a fault in some Plug-n-Play BIOS programs, it
happens occasionally that a newly installed adapter is
assigned an Interrupt Number which is already assigned
to another device. In such a case, the conflict of
Interrupt Number will cause faults in the behavior of both
devices. Then it is necessary to run the CMOS Setup
utility, and manually assign a non-conflicting Interrupt
Number.
     
1000BASE-T Gigabit Ethernet enables operation over the
extensive installed base of legacy Category 5 cabling systems and,
by default, the Category 5 cabling systems currently being
installed.
It provides optimal full-duplex 1000Mb/s Ethernet service over
Category 5e links as defined by ANSI/TIA/EIA-568-A-5. Topology
rules for 1000BASE-T are the same as those used for 100BASE-T.
Category 5 and 5e link lengths are limited to 100 meters.
