JNS Control Center
9−7 VM 3000 Installation and Operating Manual
Caution: Once the activate/reboot command has been issued, do not interrupt the process until the reboot is com-
plete. Interruptions such as sending a new command, turning off power, or disconnecting cables will have unpre-
dictable consequences.
Though the “Configuration” tab gives no indication of activity during file transfers, other tabs (described above) can be used
to determine when it is safe to initiate some other command. Depending on a several factors such as the number of boards,
configuration size, need to update the *.sys file, LAN transmission rate, LAN traffic, etc., a complete set change can take
several seconds or multiple minutes.
Activation Without a Reboot
Selecting the “Select Set Only” radio button will prevent the Control Center from sending a reboot to the boards after a set
activation. Keep in mind that the active set will not match what is on the board. If any boards reboot after this time, they will
download the new set, but they will not match other boards that have not rebooted. This can cause system instability. For this
reason, you should not usually leave the file server in this state. Reboot all boards as soon as possible.
Reboot
Clicking on the “Reboot” button sends a reboot command to all the boards. If the boards do not have the currently active set,
they will download the new set.
Backup Set
Whenever you activate a set, the name of the new set appears in the Current Set box and the name of the old set appears in
the Backup Set box.
To restore a backup set, click on the Restore Backup button. The backup set will be made the active set. The name of this set
will now appear in the Current Set box, and the Backup Set: box will be cleared. Note that the Control Center does not “swap”
sets. That is, the set that was active before you clicked on Restore Backup does not become the backup set.
The “On Activation” radio buttons have the same effect for restoring backups as they do for activating sets. That is, if the
“Select and Reboot” radio button is selected when you restore a set, the backup set will be made active, and a reboot command
will be sent to the boards. Otherwise, the set will be activated but no reboot command will be sent.
