Reverting to an Earlier Software Load
Note A revert to a maintenance release software load does not restore the database and no provisioning is
lost. All other reverts do restore the database. (A maintenance release has a three-digit release
number, e.g. 2.2.2).
Note Circuits created and provisioning performed after a software load is activated will not reinstate with
a revert. The database configuration at the time of activation is reinstated after a revert. This note
does not apply to maintenance reverts (e.g. 2.2.2 to 2.2.1).
Procedure: Revert to an Earlier Software Load
Step 1 Log into CTC.
Step 2 Record the IP address of that node.
Step 3 Display the CTC node view.
Step 4 Right click the standby TCC+ card to reveal a pull-down menu.
Step 5 Click Reset Card.
Step 6 Click Yes when the “Are You Sure?” dialog box appears.
Step 7 Click OK when the “Lost connection to node, changing to Network View” dialog box appears.
Step 8 Confirm that the TCC+ is in standby mode after the reset.
Step 9 Click the Maintenance > Software tabs.
Step 10 Verify that the protect software is Version 2.2.0 or later.
Step 11 Click Revert.
The Revert button activates the protect software load. The ONS 15454 reboots and loses the connection
to CTC.
Step 12 Wait until the software upgrade finishes.
This may take as long as 30 minutes.
Step 13 Completely close the browser.
Step 14 Restart the browser and log back into the node using the IP address recorded in Step 2.
The browser downloads the CTC applet for the standby software load.
