z
In the case of short-circuit protection, over-current protection, or overheat protection, the power
module recovers itself after the issue is addressed.
z
When a power module is deadly locked due to over-voltage protection, it does not support the
auto-recovery function. In this case, you need to power off the module, disconnect the power cord
and connect it again, and then power on the module. After all these operations, the power module
gets restored.
z
With the wrong input polarity protection function, the PSR750-D can stop power supply if the DC
input polarity is wrong. After the input polarity is corrected, the power module gets restored.

To ensure normal PoE power supply to the S5800-60C-PWR using the PSR750-D, you need to select
the RPS1000-A3 of H3C that provides a voltage range from –52V to –55V.
