Redundancy / Fault Tolerance
DS1200-3 Series
Page 57
The DS1200-3 series power supplies will allow up to 4 power supplies to be connected in an N+1 redundant
load.
Any failure of one power supply in parallel as well as hot swapping shall not cause more than a 5% change in any output.
Current share accuracy is typically 5% of full load. The Failure of one or more supplies will not cause the remaining
supplies to violate any of the input or output specifications noted in this specification including all status signals.
The latch of the DS1200-3 power supply is designed to prevent the latch from depressed if the AC cord is attached to the
power supply. In order to remove the power supply from system chassis, the AC cord must be removed first so the power
supply will always be in the powered off state during the removal from system chassis.
