Audible alarm: 3-beeps every 10 seconds
Meaning:
Low battery voltage warning.
Cause:
During an AC input power failure or brownout, the UPS determined that
the battery voltage is incapable of supporting the load for more than three
minutes.
Action:
• Verify that the MAIN INPUT circuit breaker is ON and that the UPS is
plugged into AC output.
• For systems without automatic shutdown procedure:
1. Power-off the protected equipment until AC power returns.
2. When AC power returns, power on the protected equipment.
• For systems with automatic shutdown procedure:
1. No action is required. The HP-UX system will power-down the
UPS automatically.
2. The system will power-up automatically when AC power returns.
CAUTION
Do not push the red button while the UPS is operating on battery. Damage to
the connected equipment can occur.
