4.1 Over Power Protection
The OPP function shall work at 130%~270% of rating of output power, then all outputs shut down in a
latch off mode. The latch shall be cleared by toggling the PSON# signal or by cycling the AC power.
The power supply shall not be damaged from repeated power cycling in this condition. If only one
module works inside the power supply, the OPP is at 110%~170% of rating of power supply.

The power supply shall not be damaged from repeated power cycling in this condition. If only one
module works inside the power supply, the OPP is at 110%~170% of rating of power supply.
4.2 Over Voltage Protection
Each hot swap module has respective OVP circuit. Once any power supply module shut down in a latch off
mode while the output voltage exceeds the over voltage limit shown in Table 7, the other modules should
deliver the sufficient power to the device continually.

4.3 Over Current Protection
The power supply should contain the OCP function on each hot swap module. The power supply should be
shut down in a latch off mode while the respective output current exceeds the limit as shown in Table 8.
