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
Log into the node where you want to perform the revert.
Step 1
Record the IP address of that node.
Step 2
In node view, right-click the standby XTC card to reveal a pull-down menu.
Step 3
Choose Reset Card.
Step 4
Click Yes when the "Are You Sure?" dialog box appears.

Click OK when the "Lost connection to node, changing to Network View" dialog box appears.
Step 6
Step 7 Confirm that the XTC is in standby mode after the reset.
Click the Maintenance > Software tabs.
Step 8
Click Revert.

The Revert button activates the protect software load. The ONS15327 node reboots and loses its
connection to the CTC.
Wait until the software upgrade finishes. This may take as long as 30 minutes.

Completely close the browser.
Step 11
Restart the browser and log back into the node using the IP address you recorded in Step 2.
Step 12
The browser downloads the CTC applet for the standby software load.
