IEA903A

Explanation
The operator responded to message IEA888A or IEA886A
in a way that requires the time-of-day (TOD) clock to be set.
Message
REPLY U WHEN THE ENTERED TIME OCCURS is issued when you are running MVS™ under VM or PR/SM™.

System action
When the message reads REPLY U THEN DEPRESS TOD
CLOCK SECURITY SWITCH WHEN ENTERED TIME OCCURS and when the operator
acknowledges receipt of the message, the system attempts to set a
TOD clock for a one-minute interval.  If the operator does not press
the security switch during that interval, the system issues message
IEA888A or IEA886A again.
When the message reads REPLY U WHEN
THE ENTERED TIME OCCURS, the system starts the TOD and continues processing.

Operator response
When the message reads REPLY U THEN DEPRESS
TOD CLOCK SECURITY SWITCH WHEN ENTERED TIME OCCURS, do the following: Enter REPLY id,‘U’ to acknowledge that you received
this message.
Press the security switch at the same time you respond to message
IEA888A or IEA886A.

When the message reads REPLY U WHEN THE ENTERED TIME OCCURS,
enter REPLY id,‘U’ at the same time specified in message
IEA888A or IEA886A.
