Adding a Second Power Supply
The DIGITAL Server 5220 Series ships with one power supply for normal operation.
An optional second power supply can be purchased to provide redundant power for
simple configurations or additional power for optimum configurations.
1. Turn off the server.
2. Remove the ac power cord and monitor cables, if necessary.
3. Unlock and remove the right side panel.
4. Disconnect the power supply wire harness from the existing power supply if
necessary.
5. Remove the rear fan (if present) and disconnect it from the main logic board
(see item I, Figure 3-6 and item J, Figure 3-8).
6. Slide the second power supply part way into the chassis atop the existing
power supply.
7. Attach the unused connectors of the power supply wire harness to the
second power supply.
8. Slide the power supply fully into the chassis and align with the screw holes at
the rear of the chassis.
9. Attach the power supply with the supplied screws through the rear of the
chassis.
