The “normal state” of hardware status is simply: AC Power Normal. In this normal state, AC Power Normal
will be the only status item shown in the Hardware Status display. The UPS devices, however, are capable of
reporting a number of status conditions to the host system, and in cases of additional UPS hardware status,
there will be multiple lines in the status display showing the additional status conditions.
Possible values of Hardware Status are:
• AC Power Normal — AC power at the input of the UPS device is present and within its normal tolerance
range.
• AC Power Fail — AC power at the input of the UPS device is either absent, or has drifted out of its normal
tolerance range.
• Low Battery Charge — AC power at the input of the UPS device has failed, and the UPS has engaged its
battery reserve power in order to continue to supply AC output power to the system component(s). When
engaging the Battery reserve power, the UPS device detected and reported that the battery in the UPS
hardware was in a depleted charge condition. This means that the UPS battery will only be able to supply
full output power to the system component(s) for approximately two minutes, instead of for the fifteen
minute period provided by a fully charged battery.
• Output Power Off — The UPS device reported that its output power (to the system component(s)) has
been turned off. This means that someone has (intentionally or accidentally) turned “off” the Output
Power On/Off switch on the UPS device’s front control panel.
• Bypass Mode — The UPS device reported that it had been placed into AC Power Bypass Mode. This is
only possible on some models of UPS devices, such as the A2998A 3.0 KVA UPS, that have a “Bypass
Switch”. With this switch control, a service person can “bypass” the normal flow of power through the
UPS, so that the UPS passes its AC input power directly through to its AC output plugs, without passing
the power through the normal power inverters and filters.
• UPS System Failure — The UPS device reported a System Fail status, which indicates a serious hardware
problem within the UPS device.
• UPS Inverter Failure — The UPS device reported an Inverter Fail status, which indicates a hardware
failure in the UPS’s DC-to-AC power inverter module.
• Battery Disconnected — The UPS device reported a Battery Not Present status, which indicates that the
UPS internal controller perceived that a battery module was not properly connected to the UPS device.
• UPS Charger Fault — The UPS device reported a Charger Fault status, which indicates a hardware
failure in the UPS' internal battery charger circuitry.
• Output Power Overload — The UPS device reported an Overload status, which indicates that the
equipment being powered from the UPS is drawing too much power from the UPS.
• Power Overload Shutdown — The UPS device reported an Overload Shutdown status, which indicates
that the equipment being powered from the UPS drew so much power from the UPS that the UPS
performed a “shutdown” (turned its power circuits “off”) to protect itself from the overload condition.
• High Ambient Temperature — The UPS device reported a High Ambient Temperature status, which
indicates that the UPS internal hardware detected an elevated temperature condition within the UPS
device.
• High Temperature Shutdown — The UPS device reported a High Ambient Temperature Shutdown status,
which indicates that the temperature inside the UPS device rose so high that the UPS control module
shut down the UPS power circuits to protect the UPS device from damage due to excessive heat.
• Battery Test Failure — The UPS device reported a Battery Test Fail status, which indicates that the UPS
control module detected that a battery pack failed to operate within specifications.
