Replacing the Power Supply
1
Set the replacement power supply into place.

CAUTION: Failure to replace and tighten all screws may cause electrical shock
as these screws are a key part of the grounding system.
NOTICE: Route the DC power cables as you insert them into the routing clips (if
present). The cables must be properly routed to prevent the cables from being
damaged.
3
Reconnect the DC power cables to the system board and drives.
NOTE: Double-check all cable connections to ensure that they are secure.
