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. 

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.
