System Upgrades
Application Upgrade
Step 1
Unload the application in the standby SCE platform.
Step 2
Load new application to the standby SCE platform.
Step 3
Make sure that the connection mode configurations are correct.
Step 4
Wait until the standby SCE platform finishes synchronizing and is ready to work.
Step 5
Force failure condition in the active SCE platform.
Step 6
Upgrade the application in the former active SCE platform.
Step 7
Remove the force failure condition in that platform.
Step 8
After the former active SCE platform recovers and is ready to work, it may remain the standby or can be
manually switched back to active.
Simultaneous Upgrade of Firmware and Application
Step 1
In the standby SCE platform:
a.
Uninstall the application.
b.
Upgrade the firmware (this includes a reboot).
c.
Install the new application.
Step 2
Force-failure in the active SCE platform.
This makes the updated SCE platform the active one, and it begins to give the NEW service.
Step 3
Repeat step 1 for the (now) standby SCE platform.
Since this includes a reboot, it is not necessary to undo the force failure command.
