DHCP Server Prevention
This feature prevents the PC from acting like a DHCP server.
All receive packets are passed through a DHCP filter and
are discarded if they are deemed to be destined for the
DHCP process.
Remote System Alerts
The NIC can be configured to continuously transmit a
packet to an alert target management station. If the
management station fails to receive the regularly scheduled
packet, an alert can be triggered that signals a possible
computer power loss or theft.
The NIC can also transmit a workgroup keep-alive packet
periodically while the computer is in a sleep state. This
packet prevents the computer’s workstation address from
being aged-out of switch router tables.
Hot Plug NIC Installation
If your computer supports PCI hot plug specifications, you
can add a new 3Com NIC or remove and replace a 3Com
NIC without turning off power to the computer. Hot plug
NIC installation allows you to expand connections without
taking the computer out of service. It makes
troubleshooting faster and easier because you do not need
to wait for the computer to reboot.
For instructions on performing a hot plug NIC installation,
refer to your computer documentation.
Only system administrators should configure these
features.
