XC/XCVT Card to XC10G Card Upgrade
This section explains how to upgrade dual XC/XCVT cards with dual XC10G cards in the
ONS 15454-SA-ANSI with live traffic. The procedure is non-service affecting, that is, the upgrade will
cause a switch less than 50 ms in duration.
Procedure: Upgrade the XC/XCVT Card to the XC10G Card
Upgrading XC/XCVT cards to XC10G requires that the ONS 15454 is running CTC Release 3.1 or later.
Two XC/XCVT cards must be installed in the ONS 15454-SA-ANSI, and two XC10G cards must be
available for installation. An XC/XCVT switch can cause a linear 1+1 OC-N protection switch or a
BLSR protection switch.
Step 1 Take the following precautions before performing an XC/XCVT switch to avoid causing a linear 1+1 or
BLSR protection switch:
a. Ensure the working span is active on both the local and remote nodes.
b. Ensure the working span is carrying error-free traffic (no SD or SF alarms present).
c. Lockout the protection span prior to initiating an XC/XCVT reset.
In a BLSR, place a lockout on the East and West cards of the nodes adjacent to the XC/XCVT switch
node; for example, to switch the XC/XCVT on Node B, place the lockout on the West card of Node
A and on the East card of Node C. No lockout is necessary on Node B. Before the lockout is set,
verify that the BLSR is not switched. If a lockout is set while the BLSR is switched, traffic can be
lost.
<------East [Node A] West------East [Node B] West------East [Node C] West------>
In a 1+1 protection scheme, place a lockout on the protect card and verify that the traffic is traveling
over the working span before setting the lockout.
Step 2 Determine the standby XC/XCVT card. The ACT/STBY LED of the standby XC/XCVT card is amber,
while the ACT/STBY LED of the active XC/XCVT card is green.
Note You can also place the cursor on the card graphic in CTC to display a dialog. This display
identifies the card as XC/XCVT: Active or XC/XCVT: Standby.
Step 3 Physically replace the standby XC/XCVT card on the ONS 15454 with an XC10G card:
a. Open the XC/XCVT card ejectors.
b. Slide the card out of the slot. This raises the IMPROPRMVL alarm, which will clear when the upgrade
is complete.
c. Open the ejectors on the XC10G card.
d. Slide the X10G card into the slot along the guide rails.
The fail LED above the ACT/STBY LED becomes red, blinks for several seconds, and turns off.
The ACT/STBY LED turns amber and stays lit.
e. Close the ejectors.
Step 4 In node view, choose the Maintenance > XC Cards tabs.
Step 5 From the Cross Connect Cards menu, choose Switch.
Step 6 Click Yes on the Confirm Switch dialog box.
