2.7 PDU requirements

The ActiveScale P100E3 does not come with its own power distribution unit (PDU). This section provides
information about selecting a PDU that will effectively and safely support system power consumption.

2.7.1 Power sequencing requirements

When power is first turned on in an electrical device, an instantaneous spike in current is drawn that is
sometimes several times its normal full-load current. This is called inrush current. While inrush current
might only last for microseconds, it can still pose a risk to the system and associated electrical equipment.
It is important to consider the effect that inrush current may have on your system and the electrical
equipment being used at your site.
One of the techniques that is commonly used to account for the effects of inrush current is a staggered
startup sequence. A staggered startup means the components in an electrical system are powered on in
regular intervals one after the other. This keeps the overall inrush current draw down because the power
distribution equipment only has to manage the current of one component powering on at a time rather than
an excessive current spike created by all the components powering on simultaneously.
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 caused by a simultaneous startup.

2.8 Network requirements

The ActiveScale system provides six 10G Ethernet ports for connecting to a customer's network. However,
the customer must provide six fiber cable drops from the network to the rack. The fiber cable must be LC
to LC multi- mode fiber optic patch cable (LC multi-mode 50/125mm MMF OM3 or OM4 10Gb laser
All connectors on each component are C14. The system comes with C13 to C14
cables. If these cables are not compatible with the selected PDU and power
equipment, the user must provide compatible cables. Need to verify what cables are
part of the P100E3 package.
