Abstract
A system which determines whether one of a plurality of peripheral devices on a SCSI bus is providing termination power to a bus terminator and provides termination power from a power supply associated with a host device only when none of the peripheral devices are providing termination power. The system is further configured to only provide termination power from the host device when information signals are likely to be present on the information bus. Specifically, the system only provides termination power when the host device seeks access to the information bus to thereby limit consumption of the host device's power supply.
