UPS Monitoring
UPS monitoring is a standard feature of the AS/400 operating system. QUPSDLYTIM is a
timer in the AS/400 that tells the system how long to run on UPS power before shutting
down. Each AS/400 system is initially assigned a default value for QUPSDLYTIM. Refer to
the Uninterruptible Power Supply section in the IBM document "AS/400 Advanced Series
Backup and Recovery - Advanced," SC41-3305 (for AS/400 Models 2xx and 3xx), or
"AS/400 Advanced Series Backup and Recovery - Advanced," SC41-4305 (for AS/400
Models 4xx and 5xx) or SC41-5304 (for AS/400 Models 6xx and Sxx) for information on
determining what this value is for your system, or for assistance in changing the value of
QUPSDLYTIM.
The V4R1 Backup and Recovery Guide is also available on the Customer Documentation
AS/400 Softcopy Library CD (SK3T-0118) and on the Internet at
(Take option 4 and look under the subsection called "OS/400 System Management.")
Caution:
*NOMAX tells the AS/400 to use customized shutdown software, and if
none is available it will immediately begin shutdown when utility power
fails. Do not set QUPSDLYTIM to "*NOMAX" unless you understand the
implications of the "*NOMAX" function as described in the "AS/400
Advanced Series Backup and Recovery - Advanced," SC41-3305 (for
AS/400 Models 2xx and 3xx), or "AS/400 Advanced Series Backup and
Recovery - Advanced," SC41-4305 (for AS/400 Models 4xx and 5xx) or
SC41-5304 (for AS/400 Models 6xx and Sxx).
