With power present, a battery system failure will not cause a system
interruption. As long as utility power remains present, the UPS
System will continue to power the connected IP telephony system
without interruption and will continue to condition the power against
most power anomalies. In the event of a power outage, the system
will crash.
In the event of a battery system failure, the internal batteries of the
UPS System and/or the external battery packs can be replaced
without a service interruption.
On-Line UPS System with Internal Bypass and External
Maintenance Bypass
With power present, an internal power electronics fault will result in
the load automatically being powered by a bypass path inside the
UPS. As long as utility power remains present, the UPS will continue
to power the connected VoIP system without interruption and will
continue to condition the power against basic power anomalies. In
the event of a power outage, the system will crash.
In the event of a bypass condition, the power electronics module of
the UPS should be replaced. This can be performed while the system
remains in service, as the input and output power connections are
physically and electrically separated from the power module itself.
This functionality is available presently in Tripp Lite's 5-16KVA
SmartOnline™ Hot-Swappable Modular UPS Systems.

Line-Interactive UPS System
With power present, an internal power electronics fault can result in
the load crashing. As the operational requirements of a line-interactive
UPS System are very simple when power is present, this is extremely
rare. Line-interactive power electronics failures are normally only
detected when the power fails and the UPS attempts to power the load
from its battery-driven inverter.
