5−15CM 4000 Installation and Operating Manual
DOWNLOAD NOW / REBOOT LATER (“PENDING REBOOT”)
Please refer to Figure 5−11.
In order to minimize system downtime due to changes in configuration and application code and to provide the operator the
ability to coordinate the time that the system is unavailable, modifications were made to Windows and the CM 4000 embedded
code resulting in a different configuration set and code activation procedure compared to previous Jupiter releases.
With the CM 4000, it is possible to download a configuration set and a copy of the application code without actually placing
them in operation; during this “Pending Reboot” state the CM continues to operate without interruption using the previously
executing application code and configuration. Only when the board is rebooted will the new set and application code be placed
in use.
Note: A reboot will occur when the operator executes any operation from the Control Center that will cause a re-
boot or a “Pmem Clear” to be sent to the processor, or by manually rebooting, or clearing Pmem on the processor
from the shell prompt, or by pressing the reset button.
The purpose of this technique is to provide the operator better control of system downtime. The download process, which
may be rather lengthy in large systems, does not interfere with normal operations. This allows the Reboot step, which is much
shorter (but will interrupt switching operations), to be scheduled at an appropriate time.
