The hot-swap redundant power supplies help you avoid signicant interruption to the operation of the
system when a power supply fails. You can purchase a hot-swap redundant power supply option directly
from Lenovo and install the power supply to provide power redundancy without turning off the server.
On each hot-swap redundant power supply, there is a status LED near the power cord connector. When the
LED is lit in green, it indicates that the hot-swap redundant power supply is working correctly. When the LED
is lit in amber, it indicates that the hot-swap redundant power supply is likely to fail or has failed.
3 Low-prole PCI Express card slot
It is recommended to attach a RAID card to the low-prole PCI Express card slot.
