ActiveScale™ X100 Site Requirements Guide
19
To prevent the potentially negative effects of excessive inrush current on the system, Quantum Corporation
recommends selecting a PDU that can stagger the startup sequence of the system components.
Important:
If a PDU that cannot stagger the startup sequence is used, ensure that
the PDU is rated to support the inrush current created by a simultaneous startup.
