4.6 CTC Card Reset

4.6 CTC Card Reset
You can reset the ONS 15600 cards by using the hard-reset or soft-reset commands in CTC, or by
physically reseating a card (card pull). From the node view, select a card and right-click to open a menu
with the hard-reset and soft-reset commands. Soft resets do not impact traffic, however hard resets are
service-affecting. A card must be in the Out-of-Service and Management, Maintenance (OOS-MA,MT)
service state before you can perform a hard reset.
A soft reset on the TSC reboots the TSC and reloads the operating system and the application software.
You can apply a CTC soft reset to either an active or standby TSC without affecting traffic. A CTC hard
reset temporarily removes power from the TSC and clears all buffer memory.You should only perform
a hard reset (or a card pull) on a standby TSC. If you need to perform a CTC hard reset or card pull on
an active TSC, put the TSC into standby mode first by performing a soft reset.
A soft reset on an optical card with an active port in a 1+1 protection group will result in a loss of all
DCC traffic terminated or tunneled on the active port for the duration of the reset time. A soft reset of
an optical card with a standby port in a 1+1 protection group will not affect DCC traffic. A CTC hard
reset of an optical card causes a switch to the protect card.

4.7 TSC Card Database

Each TSC card hosts a separate database; therefore, the protect card's database is available if the
database on the working TSC fails. After a database change, there might be a 30-second interval before
the TSC starts writing the data to the Flash drive. If you reset the active TSC immediately after a
database change, the change could be lost.
You can also store a backup version of the database on the workstation running CTC. This operation
should be part of a regular ONS 15600 maintenance program at approximately weekly intervals and
should also be completed when preparing an ONS 15600 for a software upgrade or a pending natural
disaster, such as a flood.
Note The Internet Inter-ORB Protocol (IIOP) port is not backed up and restored.
Note The ONS 15600 does not allow you to restore a database from one node to another node. You can install
a database from one node on another node by using the Configure Node option on the Maintenance >
Database tab.

4.8 Software Load Revert

Before you upgrade to Software Release 6.0, you must create a database backup. If you later need to
restore the original working software load from the protect software load, CTC displays a prompt
requesting the location of the backup. Any provisioning performed with Software R6.0 will be lost when
the Software R1.1.x backup is restored.
After a software load is activated (upgraded to a higher software release), any circuits created and
Note
provisioning performed will not reinstate if an older database is restored. The database configuration at
the time of activation is reinstated after a revert.
