2.3.3 Monitoring
Note: PDU monitoring is only available when using PDUs ordered directly from
Quantum Corporation specifically for the ActiveScale X100. Contact customer
support if PDU monitoring is a requirement in your environment.
Local Monitoring
The monitoring requirement is optional. However, Quantum Corporation recommends that each PDU shall
include local (on board) indicators of the status of each branch circuit. These will show the following
information: Branch Circuit Protection Device State:Closed circuit: Open circuit.
The type of monitoring and any protocols that are used for monitoring PDUs are left to the discretion of the
customer.
Parameters Monitored
The PDU OIDs that are monitored by the Active Scale system are the following:
Communication Interface
The communication interface is dependent on the capabilities of the PDU. All interfaces will be defined
and maintained by PDU vendor. An example of such an interface is:
2.3.4 Miscellaneous requirements
Power sequencing and inrush
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.
