NTP- D94 Upgrade STM-N Cards and Spans Automatically
Step 2 Complete the “DLP-D60 Log into CTC” task on page 17-49. If you are already logged in, continue with
Step 3.
Step 3 Ensure that no alarms or abnormal conditions (regardless of severity), including LOS, LOF, AIS-L, SF,
SD, and FORCED-REQ-RING are present. See the “DLP-D298 Check the Network for Alarms and
Conditions” task on page 19-83 for instructions.
Note During the upgrade/downgrade some minor alarms and conditions display and then clear
automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than
MSSP-OSYNC, which will clear when the upgrade/downgrade of all nodes is complete. If any
other service-affecting alarms occur, Cisco recommends backing out of the procedure.
A four-node MS-SPRing can take up to five minutes to clear all of the MSSP-OSYNC alarms.
Allow extra time for a large MS-SPRing to clear all of the MSSP-OSYNC alarms.
Step 4 In network view, right-click the span you want to upgrade.
Step 5 Choose Span Upgrade from the shortcut menu (Figure 12-1).
Figure 12-1 Span Upgrade Shortcut Menu
The Span Upgrade wizard shown in Figure 12-2 appears. The information displayed in Figure 12-2
depends on the card that is upgraded. Follow the instructions in the wizard to complete the span upgrade.
Note The Back button is only enabled on Step 2 of the wizard; because you cannot back out of an
upgrade through the wizard, close the wizard and initiate the manual procedure if you need to
back out of the upgrade at any point beyond Step 2.
