Chapter 12 Upgrade Cards and Spans
NTP-A95 Upgrade OC-N Spans Manually
Caution As indicated by the wizard, when installing cards you must wait for the cards to boot up and become
active before proceeding to the next step.
Note Remember to attach the fiber after installing the OC-N cards.
Note The span upgrade process resets the line’s CV-L threshold to factory default. The CV-L threshold
is reset because the threshold is dependent on line rate.
Step 7 Repeat Steps 4 through 6 for additional spans in the ring.
Stop. You have completed this procedure.
NTP-A95 Upgrade OC-N Spans Manually
Note OC-N card transmit and receive levels should be in their acceptable range as shown in the specifications
section for each card in Table 2-3 on page 2-15.
Note In this context the word “span” represents the OC-N path between two nodes. The words “span endpoint”
represent the nodes on each end of a span.
Note If any of the cross-connect cards reboot during the span upgrade, you must reset each one when the span
upgrade procedure is complete for all the nodes in the ring.
Step 1 Determine the type of span you need to upgrade and make sure you have the necessary cards. Valid span
upgrades include:
Purpose This procedure upgrades OC-N speeds within BLSRs, path protection
