The QSW-7600 provides N+N redundancy of power supply. You are recommended to use
multiple power supplies for the equipment to ensure its continuous and stable operation
by avoiding the impact of unexpected power failures on the equipment.
When the dual power supply is applied, the type of the power supply should be identical.
If a power supply system is equipped with a leakage protector (also referred to as "leakage
current switch" or "leakage current breaker"), the rated leakage action current of each
leakage protector is greater than twice of the theoretical maximum leakage current of all
the power supplies in the system. For example, if a system is equipped with eight identical
power supplies, the leakage current of each power supply is equal to or less than 3 mA,
and the leakage current of the system totals 24 mA. A leakage protector with 30 mA rated
action current supports less than five power supplies (that is, Action current of the leakage
protector/2/Maximum leakage current of each power supply = 30/2/3 = 5). In other words,
the leakage protector with 30 mA rated action current supports no more than four power
supplies. In this case, the eight power supplies in the system require at least two leakage
protectors with 30 mA rated action current and each leakage protector supports four
power supplies. If power supplies in a system differ in models, the rated leakage action
current of each leakage protector divided by two is greater than the sum of maximum
leakage currents of all the power supplies. The rated leakage non-action current of a
leakage protector shall be 50% of the leakage action current. Take a leakage protector
