2.8.4 Uninterruptible power supply (UPS) connection (optional)
Using an uninterruptible power supply (UPS) enables the stable supply of electrical power to the system in case of power failure, widespread power outage, etc.

If the customer has ordered UPSs, use a separate UPS for each power supply system. Connect PSU#0 and PSU#1 to the input power supplies of different systems.
Figure 2-21 shows power supply systems with UPS connections.
