Fujitsu ETERNUS DX100 S4 - Required Number of Outlets;Sockets; Circuit Protectors; Table 19 Required Conditions for Distribution Board Circuit Protectors

Required Number of Outlets/Sockets
The number of power outlets/sockets required to install the
ETERNUS DX depends on the number of drive enclo-
sures and power distribution units.
It is recommended that the power cords of the drive enclosures are connected to the power distribution units
that are installed in the same rack. Secure the necessary number of power outlets within the same rack to avoid
connecting power cords to power outlets in different racks. It may be necessary to purchase additional power
distribution units depending on the installation locations of enclosures.
■
Without Power Distribution Units
Two power sockets are required for every controller enclosure, 2.5" type drive enclosure, and 3.5" type drive en-
closure.
Four power sockets are required for each high-density drive enclosure.
■
With Power Distribution Units
Two power sockets are required for each power distribution unit.
Circuit Protectors
Protection coordination must be secured between the distribution board circuit protectors and the ETERNUS DX
or power distribution units to protect the
ETERNUS DX by blocking the failed circuit immediately when a power
supply input error occurs.
Distribution board circuit protectors must satisfy the following required conditions and breaking characteristics.
■
Required Conditions
The distribution board circuit protectors must satisfy the required conditions that are listed below.
