Patent attributes
A remote power sensing system for a hard disk bridge coupled to a drive bay uses a power sensor connecting a bridge to an energization control in the drive bay. The power sensor can be a cable or the like to provide a power detection signal to the bridge. The drive bay energization control selectively provides power to the drive bay (for example, by a key switch or the like). Energization of the drive bay may also energize a drive bay device such as a fan that also functions as an energization proxy. The power sensor connects the bridge to the energization proxy so that energization of the drive bay can be detected via the energization proxy and power sensor. When the sensor detects power provided to the drive bay, the bridging function of the bridge is enabled.
