OPERATION

Operating Modes

The Avaya 9130 front panel indicates the UPS status through the UPS
indicators (see Figure 13 on page 33).

Normal Mode

During Normal mode, the indicator illuminates solid and the UPS is
powered from the utility. The UPS monitors and charges the batteries as
needed and provides filtered power protection to your equipment.
The UPS may at times silently implement a High Alert mode, usually
when incoming utility conditions are unfavorable. In High Alert mode,
the UPS disables the battery support test to ensure maximum capacity
from the batteries if needed. The UPS will remain in High Alert for
24 hours or until changed by a Power Strategy command before
returning to its previous mode.
Optional High Efficiency and Energy Saving settings minimize heat
contribution to the rack environment. See "User Settings" on page 36.

Battery Mode

When the UPS is operating during a power outage, the alarm beeps
once every five seconds and the indicator illuminates solid.
When the utility power returns, the UPS transfers to Normal mode
operation while the battery recharges.
If battery capacity becomes low while in Battery mode, the indicator
flashes slowly and the audible alarm beeps once every second. If the
"Battery Low" alarm is set, the indicator also illuminates solid. This
warning is approximate, and the actual time to shutdown may vary
significantly.
NOTE Depending on the UPS load and the number of Extended Battery Modules (EBMs)
connected, the "Battery Low" warning may occur before the batteries reach 25% capacity.
See Table 18 on page 75 for estimated runtimes.
When utility power is restored after the UPS shuts down, the UPS
automatically restarts.
