from the server. Voltages are present at various locations within the server whenever an AC power
source is connected. This voltage is present even when the main power switch is in the off position.
To remove the backplane:
The backplanes for the servers with 4 LFF HDDs and 8 SFF HDDs share the same replacement

procedures.
