A value of No in this column indicates that either initialization of the UPS device failed (in which case there
will be log entries in the system log file showing what errors were encountered during initialization), or that
Initialization is in progress but not yet completed (in which case, a later repetition of the STATUS command
will show a Yes in this column, denoting completion of initialization).
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:
• 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.
• 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.
• 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.).
• 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 HP e3000 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.
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:
• Normal — AC power coming into the UPS device is normal, and the UPS device is supplying filtered AC
power to the system component(s).
• 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.
Hardware Status The Hardware Status field (column) of the status display shows any and all of the UPS
hardware status conditions that each UPS device has reported to the UPS Monitor Process, as of the most
recent observation.
