UPS is in Battery mode
Action
: Save files, and then power down connected load devices.
UPS frequently switches between utility and battery
power
Action
:
1.
Check the input voltage, and then reconfigure the UPS menu options (on page
73
).
2.
Contact a qualified electrician to verify that the utility power is suitable for the UPS.
Battery fault
Action
: If a battery fault occurs, replace the batteries.
UPS backup time is short
Action
:
1.
Verify that the battery pack circuit breakers are switched to the On position.
2.
Verify that the life of the batteries did not exceed the limit.
3.
If the condition persists, contact an HP authorized service representative.
Low battery shutdown
Possible cause:
An ungraceful shutdown of any attached servers occurs when the UPS is in a low battery condition.
Action:
1.
Verify that the power management software is not delaying the shutdown of attached servers when the
UPS is in a low battery condition.
2.
Allow the UPS batteries to charge for 24 hours.
Deep Sleep mode
To prevent battery modules from discharging when the charger is not available, the battery pack enters Deep
Sleep mode. Each cell displays Z V on the LCD screen. Deep Sleep mode occurs under the following
conditions:
•
The UPS is in Bypass mode.
•
The UPS charger limit is set to NO CHARGE and at least one battery module has a voltage of less than
36 V.
When these conditions are cleared and no battery module has a low voltage, the battery pack wakes up from
Deep Sleep mode automatically.
