PSU: Power Supply Units
CP: Circuit Protectors
Do not connect just one power distribution unit to multiple ETERNUS storage systems. In addition, do not con-
nect just one circuit protector of a power distribution unit to multiple ETERNUS storage systems.
When power cords are connected to a single power supply line, the connections are more secure if a one-to-one
connection is made between each power cord and circuit protector of the distribution board.
