close each dialog.
The upgrade process takes approximately 3 minutes:
 firmware upgrade (approximately 2 minutes)
 reboot, reestablish I/O connections (1 minute)
During the firmware upgrade, the I/O communications with the adapter module is interrupted. After
the hold up time (see page 54) expires, the I/O modules move to the security mode, that is, their
I/O values = 1.
