After installing all hot-swap drives, if you have removed the security bezel, reinstall it.
Hot-swap power supply replacement
Follow these instructions to replace a power supply unit in the ThinkAgile HX 1521-R, HX3521-G, HX5521,
HX5521-C, HX7521 Certified Node server.
The ThinkAgile HX 1521-R, HX3521-G, HX5521, HX5521-C, HX7521 Certified Node servers use two power
supply units. Those power supplies are redundant when using 208 - 230V input power, allowing one power
supply to meet the needs of the node. Losing one power supply may not impact node operation; however,
replace a failed power supply as soon as possible to restore redundancy.
