Some power supplies support a Master/Slave relationship:
When one power supply is set to master(1) and the
other is set to slave(2), the master will supply
all power to the cabinet, and the slave will take
over if the master stops supplying power. This is
useful when (for example) one supply is attached to a
wall socket and the other to a battery backup. The
cabinet can be directed to only draw power from
batteries when there is no alternative.
When both power supplies are set to master(1), the
results are determined automatically.
WARNING: It is up to the system administrator to
ensure that at least one power supply is set to
master(1). It is illegal to set all power supplies to
slave(2). If this occurs, the cabinet may lose
all power under certain circumstances, even if
power is available.
In some cases, the Master/Slave relationship cannot
be configured via management; it is determined by
other means, such as the slot locations in which the
supplies are installed, or switches on the supplies.
In this case, attempts to change the value of this
variable from management will be ignored. The
ConfigMode variable will have the value hardware(2)
in this case.
If a supply does not support (or can disable) Master/Slave
functionality, the value shared(3) is returned. In this
case, all ready power supplies share the load evenly.
A single CPSMP110 control unit can support multiple
subdevices of this type.
