Servicing Power Supplies 135
Servicing Power Supplies
The server contains two power supplies, which provide 1 + 1 power redundancy. If you need to
replace a power supply, you can do so while the server is operating.
Note - To take full advantage of the server's power redundancy, plug the two power supplies
into separate power sources wired to two separate circuits.
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.
