Upgrading to Release 6.1
NOTE:
If SPM is already installed, the :HOFRPHWR630 screen that
appears when you start SPM identifies the version on both the last
line of the console simulation window and in the upper left corner of
the screen. If you are working with Version 6.25, V6 appears in the
upper left-hand corner of the screen and 9HUVLRQ appears
on the last line of the console simulation window.
If an upgrade from Release 3.0 or before is to be performed, a new processor
must be installed. If an upgrade from Release 3.1 and later is to be performed, a
forced installation card is required.
To upgrade to Release 6.1, follow these steps:
!If the current system programming is to be used in the upgraded
system, back up system programming.
See “Backing Up System Programming,” next in this chapter, for details.
!Remove the control unit housing.
See “Removing the Control Unit Housing,” later in this chapter, for
instructions.
!Power down the system.
See “Powering Down the System,” later in this chapter, for instructions.
!Install the new processor module.
See “Upgrading the Control Unit,” later in this chapter, for instructions.
!Insert the Release 6.1 forced installation card.
!Power up the system. A frigid start returns system programming to
default values, when the system powers up.
See “Completing the Upgrade,” later in this chapter, for instructions.
!If the current system programming is to be used in the upgraded
system, convert the backup file and restore system programming.
See “Completing the Upgrade,” later in this chapter, for instructions.
