例如：
如果安装了三个8 A冗余电源（N=3），则大

The proper method for starting systems powered by summable power supplies is to
insert both supplies in the backplane in an unpowered state, and then apply power
to each supply. For 140CPS11410, 140CPS21400, and 140CPS414 models, there
is no requirement to power each supply simultaneously. For 140CPS11420, or
wherever this module is operated with a 140CPS11410, the delay between the two
powering times should not be greater than five seconds. The system designer must
realize that the operation of the summable supply described above is independent
of total backplane load, i.e., even if the total load on the backplane is less than 8 A,
if there are two summable supplies installed in the backplane, the system POK is
generated as shown in this section.
For the special case of a single summable supply used as a standalone, the system
POK generation reverts to the standalone case as shown previously in this section.

Redundant
Power Supplies
Five redundant power supply models are offered:
Similar to the summable supplies, the Quantum redundant power supplies also
contain circuitry which forces the installed power supplies to share output current
almost equally. An important difference between the summable and the redundant
supply lies in the system POK generation circuitry.
The Quantum system POK signal in systems powered by redundant power supplies
is true (power is OK) if either or both internal POK is true. The following figure shows
the internal Quantum redundant supply POKs are ORed to create the Quantum
System POK.
Another important difference from the summable system is the total available
system backplane loading. If there are N redundant power supplies installed in a
backplane, the total backplane load must not exceed the capability of N – 1 supplies.
For example:
 If three 8 A redundant power supplies are installed (N = 3), the maximum
backplane load available for redundant operation is the current sourced by N – 1
( = 2) supplies, which is 16 A.
 if two 8 A power supplies are installed in the backplane (N = 2), the maximum
backplane load available for redundant operation is the current sourced by N – 1
( = 1) supplies, which is 8 A.

If these constraints are observed, then in a system of two or three redundant
supplies, one supply (it doesn’t matter which one) is hot-swappable. This is possible
because there is excess capacity in the N – 1 remaining supplies to source the
backplane current while the Nth supply is being swapped.
An obvious extension to this argument is that a single redundant power supply may
be used as a standalone supply (but the lowest cost solution will be achieved by
using a summable or standalone supply for this application).

Compatibility
Issues
Power supplies:
 With the exception of standalone models, power supplies with the same model
number are always compatible when installed in the same backplane.

Do not mix different models of power supplies on the same backplane, except in
the following combinations:
 One 140CPS11420 and one 140CPS11410 power supply may be installed for
configurations consuming more than the rated current of one supply. In this
case the total load capacity is 16 A @ 60° C.
 One 140CPS12420 and one 140CPS22400 power supply may be used for
configurations requiring power for uninterrupted system operation with
redundancy between an AC voltage source and a 24 Vdc voltage source. In
this case, the total load capacity is 8 A @ 60° C. Three redundant supplies can
also be mixed in a backplane. See p. 707 for details.
 One 140CPS12420 and one 140CPS42400 power supply may be used for
configurations requiring power for uninterrupted system operation, with
redundancy between an AC voltage source and a 48 Vdc voltage source. In
this case the total load capacity is 8 A @ 60° C. Three redundant supplies can
also be mixed on a backplane. See p. 707 for details.

Do not mix DC input power supplies into the same backplane as the
corresponding AC version.

Do not use a standalone power supply in combination with any other supply in the
same backplane.
DIO:
 While it is possible to use a standalone or a summable power supply with a DIO
drop (as long as the DIO input is left unpowered), it is not possible to use a
redundant supply with the DIO drop.

The added power supply must not be included in the system I/O map.

The added power supply need not be of the same type as the DIO adapter. AC
powered supplies may be
