Breaker Characteristics

The breaker characteristics for the SPARC M12 systems must be taken into
consideration to allow the devices to be used under the right conditions. Use circuit
breakers that meet the following special conditions for the power distribution panel
breakers of the computer equipment.
Table 2-11
Table 2-11 Distribution Panel Breaker Capacity of the Computer Equipment
Device Name
SPARC M12-1
PCI expansion unit
Note - If you use a power distribution unit between the distribution panel for the computer
equipment and a device, use one whose breaker capacity matches the value in
the rated value of the device. In this case, connect the power distribution unit to a distribution
panel breaker for the computer equipment with a capacity equal to or greater than the input
capacity of the power distribution unit.
Figure 2-14
As the distribution panel breaker for the computer equipment, use a breaker with
cutoff characteristics that have a Long-time delay type equivalent to cutoff
characteristic D (IEC/EN 60898-1) shown in
characteristics.
If a breaker with shorter cutoff characteristics than cutoff characteristic D is used, the
breaker may cut off power earlier when the power supply unit of a device fails. In
