Power supply for NFx500-SR40E
(1) Power plug
The power plug is intended to supply power to the disk array unit. Connect the supplied power cord to
the power plug and the plug of the power cord to an outlet of 100 VAC power at 50 or 60 Hz.
The disk array unit has a redundant power configuration to prevent the entire unit from being shut
down by a single failure. In this configuration, connect two power cords for use of the disk array unit.
While the disk array unit NFx500-SR40E can accept power in the range of 100 -
240 VAC (50/60 Hz), the power cord shipped with the disk array unit can only
accept 100 – 120 VAC. Use 100 – 120 VAC (50/60 Hz) when the supplied power
cord is used. Using power of a different voltage may cause electric shock, smoke,
and/or fire to occur.
(2) Power switch
The power switch is used to turn on/off the power of the disk array unit.
The disk array unit has a redundant power configuration to prevent the entire disk array unit from
shutting down due to a single failure. Therefore, turn on/off both of the two power switches when
operating the disk array unit.
