5.4.1 Hot Swap Functionality
Hot swapping is the process of inserting and extracting a power supply from an operating power
bay. During this process, the output voltages will remain within the limits specified in Table 31,
and the system will continue to operate normally.
5.4.2 Output Current Rating
The combined continuous output power for all outputs will not exceed 1570W. Each output has
a maximum and minimum current rating shown in Table 32.

1. Values are at the system level. For 1+1 redundant systems the load each supply provides is based on its
current-sharing accuracy.
2. Peak +12V output power not to exceed 15 seconds in duration. Maximum duty cycle is 5%.
3. For 85-121VAC operation (100/110VAC rated).
4. For 103.5-139VAC operation (115/120/127VAC rated).
5. For 170VAC, and higher, operation (200/208/220/230/240VAC rated).
5.4.3 Over- and Under-Voltage Protection
The power supply provides latch mode over and under voltage protection as defined in the
following table. A fault on any output will cause the rest of the outputs to latch off. See note 3
below the table.

1. In standby mode, the power supply does not latch off due to an under-voltage condition.
2. In standby mode, the power supply may or may not latch off due to an over-voltage condition.
3. A fault on any output other than +3.3V
stby
will not cause the +3.3V
stby
to turn off. A fault on +3.3V Standby
causes the other outputs to turn off.
