Servicing Power Supplies 133
Servicing Power Supplies
The power supplies are hot-service components that can be replaced at any time. There are no
slot restrictions for power supplies. Any supported power supply may be installed in any of the
four power supply slots. However, in order to maintain full power redundancy, all four power
supply slots must be occupied with functioning power supplies, and all four power cords must
be plugged in.
For the location of the power supplies, see “Front Panel Components (Service)” on page 14 .
Note -
To take full advantage of the server's power redundancy, plug the power supplies into
separate power sources wired to two separate circuits, using a 2+2 configuration.
Caution - This procedure requires that you handle components that are sensitive to electrostatic
discharge. This discharge can cause failure of server components.
These topics describe service procedures for the power supplies in the server.
