UPS Utility Manual

3.5.3.5 State
The State field (column) of the status display shows the operating state of the UPS device as perceived by the UPS Monitor
Process.
Possible values for State are:
o
Configured
- The UPS device has been found in the system I/O configuration tables and has been recognized by the
UPS
Monitor Process as a valid UPS device, but initialization of the UPS device has not yet begun.
o
Initializing
-
Initialization (a sequence of commands that brings the UPS device "online" and ready for monitoring) of the
UPS device is in progress in the UPS Monitor Process.
If it completes successfully, the UPS will be advanced to the
Monitoring state. If initialization fails, the UPS device will be placed in the Down/Broken state.
o
Monitoring
- This is the normal "steady-state" of
the UPS, in which the UPS Monitor Process is "watching" the UPS for
its hardware events, such as power failures and other hardware
conditions (e.g. high temperature, low battery charge, output
power overload, etc.).
o
Down/Broken
- This state indicates that the UPS Monitor Process encountered severe errors when trying to initialize
the UPS device, or while monitoring the UPS after a successful initialization.
The UPS Monitor Process will declare a UPS device to be "Down/Broken" only after a number of retries of
the operations
that experienced errors have also failed.
This state most likely indicates some hardware related problem with the UPS device or with the RS-
232 serial I/O interface
hardware (including cabling connections) used by the HP3000 system to "talk to" the UPS device.
NOTE
If a UPS device ever does enter the Down/Broken state, then that UPS device is no
longer being monitored by the UPS Monitor Process and after correcting the
hardware problem, the UPS Monitor Process must be restarted (by means of a
RESTART command, or by a STOP followed by a START command, or by a
system boot) in order to begin monitoring that UPS device again.
3.5.3.6 Power
This field (column) of the status display shows the most recent "power status" of the UPS device as observed by the UPS
Monitor Process.
Possible values of this field are:
o
Normal
-
AC power coming into the UPS device is normal, and the UPS device is supplying filtered AC power to the
system component(s).
o
Failed
- The UPS detected a loss of, or a variation from acceptable tolerances of, incoming AC power, and reported
that power status to the UPS Monitor Process. Currently, a "power fail" condition has been declared
by the UPS
Monitor Process. The UPS device is supplying battery reserve
power to the system component(s), unless its battery has been
exhausted, in which case power to the system component(s) has truly failed.
