1. A system for communication between components in a computer storage system, comprising: a drive enclosure device having a plurality of disk drives; and a switch module electrically coupled to the drive enclosure device and having a plurality of physical layer links (PHYs), wherein the switch module generates out-of-band (OOB) signals to transmit to the drive enclosure device, detects an active drive enclosure device by interrogating the PHYs, and sends a serial management protocol (SMP) instruction to the drive enclosure device to perform a task.
