Reset operations are driven by power management, system failures, and other situations. When a reset request is made, the PLM and PSM firmware can respond with a hard reset or a soft reset. A soft reset can gracefully close down a subsystem for power management needs.

Quiescent Components

Prior to asserting a reset, the PLM and PSM firmware can attempt to put the affected logic into a quiescent state by using the isolation functionality in the ingress or egress ports of the interconnect switches. The functionality of these ports is described in the Switch Architecture section.
