ActiveScale™ X100 Site Requirements Guide

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.
Table 2 - 4. Recommended startup order
For an example of the exact programming sequence used by Quantum Corporation power supplies, refer to
the cabling section of the ActiveScale X100 Support Guide .
Safety
The PDU used shall comply with the safety standards of the country that rack is installed in.
Electromagnetic Compatibility
The PDU used shall comply with the Electromagnetic Compatibility (EMC) agency of the country that the
rack is installed in.

startup order
Component Delay
1 System Interconnects 3-5 seconds for each device
2 System Nodes 3-5 seconds for each device
3 Management Interconnect 3-5 seconds for each device
4 Storage Enclosure Basics 1-2 minutes for each device
Note:
The longer delay for Storage Nodes allows all the
disks in the Storage Enclosure Basics to spin up
completely.
5 Storage Nodes 3-5 seconds for each device
