This read-write Integer32 (0..255) sets, in seconds, how long the PDU waits before turning outlet 10 back on after being commanded (or restored) to power on. An admin uses this power-on delay to stagger a sequenced restart across the PDU's outlets, avoiding an inrush current surge if every connected device tried to boot simultaneously. For example, an admin configures outlet10ONdly to a long delay so devices on this outlet are held back until nearly all other outlets have already completed their power-on sequence.
