Console Messages
The UPS sends error messages and warnings via its RS-232 port to the computer system.
To receive these messages, your computer system needs HP-UX version 9.04 (or later) or
MPE/iX version 5.0 (or later).
The operating system attempts to display a message on the system console and in a
diagnostic log. Under some alarm conditions, however, it may not be able to. The message
may be delayed until AC input power has been restored. In other cases, the message may
be lost. For a complete listing of diagnostic messages and warnings, refer to Appendix A,
“HP-UX UPS Monitor Error Messages,” or Chapter B, “MPE/iX UPS Monitor Error
Messages.”. The messages are also listed in the index to help you find a specific message.
Operating System Assistance
If your computer system is HP-UX version 9.04 (or later), the operating system provides
assistance in troubleshooting the UPS equipment. In addition to displaying error and
warning messages from the UPS, the operating system can automatically shut down the
equipment.
When AC power fails, and the UPS switches to battery power, the HP-UX operating
system receives a message from the UPS. After one minute on battery power, the operating
system automatically sends a shut down message to the UPS and shuts itself down in five
minutes. When AC power returns, the operating system automatically restarts itself. No
operator intervention is required to shut down and restart the equipment, unless some of
the switches are incorrectly set. The default number of minutes for shutdown delay and
shutdown timeout can be changed for your specific needs. For information on setting the
shutdown parameters, refer to Chapter C, “Configuring the OS for the PowerTrust UPS.”.
Without Operating System Assistance
If your computer system is an MPE/iX system or a version of HP-UX earlier than 9.04,
then it cannot provide assistance in a power fail situation. During an AC power failure,
operator intervention is required to shut down the protected equipment and the UPS
before the battery power is depleted.
In cases described in this chapter, suggested actions are provided with and without
operating system assistance.
