Viewing a List of UPS Units
To view a list of UPS units supporting the VessRAID:
1. Click the Subsystem icon in Tree View.
2. Click the UPS icon.
3. Click the Information tab in Management View.
Information in the UPS List includes:
• UPS ID – Click the ID number to view the UPS Tab.
• Operational Status – OK means Normal.
On AC means the UPS is connected to a viable external AC power
source.
On Battery means the external AC power source is offline and the UPS
is running on battery power.
• Model Name or Number
• Battery Capacity – Backup capacity expressed as a percentage.
• Loading Ratio – Actual output of UPS as a percentage of the rated
output. See the Note below.
• Remaining Backup Time – Number of minutes the UPS is expected to
power your system in the event of a power failure.
Note
The maximum recommended Loading Ratio varies among models
of UPS units. The general range is 60% to 80%. If the reported
Loading Ratio exceeds the recommended value for your UPS unit:
• Have fewer subsystems or peripherals connected to this UPS
unit.
• Add more UPS units, or use a higher-capacity UPS unit, to
protect your RAID systems.
