C UPS and Data Center Power Configurations
This appendix provides examples of UPS and data center power configurations, and:
•
Specifies the UPS configurations supported on the NonStop system including the
recommended UPS configuration for when the disk drive write cache is enabled.
•
Identifies the non-supported UPS configurations that should not be used with the NonStop
system when the disk drive write cache is enabled.
•
Explains why some configurations are not supported.
•
Informs you of what you must do to prevent data loss.
NOTE:
All example UPS configuration illustrations in this appendix show NonStop BladeSystem
hardware, but these configurations are supported on all NonStop platforms and can be used with
single-phase and three-phase UPS.
IMPORTANT:
You must change the ride-through time for a Hewlett Packard
Enterprise-supported UPS from the manufacturing default setting to an appropriate value for
your system. During installation of a NS2300 system or HPE UPS, your service provider can
refer to the "Setting the Ride-Through Time and Configuring for Maximized Runtime" procedure
in the
NonStop i NS2100 and NS2300 Hardware Installation Manual
for these instructions.
