NTRODUCTION
UPS/400 is power monitoring software that continuously monitors your UPS hardware, 24 hours a day, 7
days a week, for alerts indicating an AS/400 system power fluctuation or loss. Upon detecting a notification,
UPS/400 sends messages to users advising them of pending power outage. If power is not returned,
UPS/400 notifies users to sign off the system, takes control of your system, and begins an orderly
shutdown. If at any time during the shutdown period power is restored, UPS/400 resets the system to
normal and informs all users.
User-friendly menus and pop-up windows provide an easy, non-technical approach to installation and
customization. UPS/400 is delivered with a sample shutdown plan already in place, so you can activate the
product with or without further tailoring.
UPS/400 includes a simulated UPS power failure test function that utilizes the shutdown criteria shown on
the System Attributes display. The test function permits you to test your system attributes (whether
defaulted or customized) in simulation mode. UPS/400 executes the specified parameters for each step,
and sends messages to the system operator and active users at each of the six time intervals that you
specify. In this way, you can test and modify the message intervals and message notifications prior to
activating the actual UPS/400.
You can customize UPS/400 to your environment so that messages are sent at up to six intervals that you
specify. UPS/400 also ends active processes and subsystems according to your present instructions.
Field-sensitive help information is provided to assist you in understanding and customizing UPS/400.
In the event of a power loss, system shutdown activities will occur in four basic stages.

Once installed and customized, UPS/400 will interact with the system administrator and online users to
effect an orderly shutdown if a UPS power loss occurs. Actions will be taken in the following stages:
Stage 1: Alert
• The system operator is notified that power has been lost and UPS/400 has taken control.
• Users are alerted that they are on UPS power and asked to complete critical tasks before possible
signoff.
Stage 2: Preliminary Shutdown
• Continued periodic notifications of shutdown severity status are sent to the system operator
• Specified Job Queues are held
• Users are notified to end tasks and log off due to continued outage
• Specified subsystems are being ended in anticipation of continued power outage
• User specified procedures (optional) are run at indicated time intervals
Stage 3: Critical Shutdown
• System operator is notified that full system shutdown has been initiated
• All remaining subsystems are ended
• All active users are logged off
• A full system AS/400 power down is performed
