3C905C NIC Overview 15
Using the Workgroup Keep-Alive Packet
The 3C905C NIC can transmit a workgroup keep-alive
packet periodically while the PC is in a sleep state. This
packet prevents the PCs workstation address from
being aged-out of switch and router tables.
For instructions on enabling or disabling the
workgroup keep-alive packet, see “Configuring the
Workgroup Keep-Alive Packet” in Appendix D.
Using Remote System Alerts
The 3C905C NIC can be configured to continuously
monitor the PC and transmit a remote system alert to an
alert target management station when a specific event,
such as a power problem or a case intrusion, is detected.
Remote System Alerts Requirements
To generate remote system alerts:
■ The 3C905C NIC must be connected to the
PC motherboard using the NIC SOS or SMBus
(SMB) connector.
See your PC documentation or contact your PC
manufacturer if you are unsure whether the NIC can
be connected (or already is connected) to the PC
motherboard using one of these connectors.
■ The alert target management station that is to receive
the alerts must have software that supports the
Platform Event Trap Format (PETF) specification for
remote system alerts.
See your management station software documentation
if you are unsure whether it supports the PETF
specification, the packet format used by the
3C905C NIC.
Supported Remote System Alerts
A PC can support a maximum of seven remote system
alerts. The remote system alerts that are supported by
your PC depend upon your PCs configuration.
