This read-write integer (0-255) sets outlet15ONdly, the number of seconds the CPI Unity PDU waits before energizing outlet 15 once a power-on-all or startup sequence begins. Staggering this delay keeps outlet 15's device from drawing inrush current at the exact same instant as outlets with shorter delays, which is what prevents a whole-rack power restoration from tripping an upstream breaker. For example, an administrator could set outlet15ONdly to 10 seconds so the equipment on outlet 15 only powers up after earlier outlets in the startup sequence have already stabilized.
