DLP- D295 Perform a Manual Span Upgrade on an SNCP

Step 8 Verify that the transmit signal falls within the acceptable range. See Table 2-4 on page 2-17for STM-N card transmit and receive levels.

Step 9 Complete the “DLP-D338 Install Fiber-Optic Cables for MS-SPRing Configurations” task on

page 20-37to attach the fiber to the cards. Wait for the IMPROPRMVL alarm to clear and the cards to become active.

Step 10 When cards in both endpoint nodes have been successfully upgraded and all the facility alarms (LOS, SD, or SF) are cleared, remove the Force switch from both endpoints (nodes) on the upgraded span. See the “DLP-D194 Clear an MS-SPRing Force Ring Switch” task on page 18-82.

Step 11 Repeat these steps for each span in the MS-SPRing. When all spans in the MS-SPRing have been upgraded, the ring is upgraded.

Step 12 Return to your originating procedure (NTP).

DLP-D295 Perform a Manual Span Upgrade on an SNCP

Purpose	This task upgrades SNCP spans to a higher optical speed. Repeat the
	task to upgrade each span, and thus the entire ring, to the higher optical
	rate. To downgrade an optical span in an SNCP ring, repeat this task but
	choose a lower-rate card in Step 5.
Tools/Equipment	Higher-rate cards
	Compatible hardware necessary for the upgrade
Prerequisite Procedures	DLP-D60 Log into CTC, page 17-49
Required/As Needed	As needed
Onsite/Remote	Onsite
Security Level	Provisioning or higher

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Step 1 Complete the “DLP-D197 Initiate an SNCP Force Switch” task on page 18-84to apply a Force switch on the span that you will upgrade.

Step 2 Remove the fiber from both endpoint nodes in the span and ensure that traffic is still running. Step 3 Remove the STM-N cards from both span endpoints.

Step 4 For both ends of the span, in node view right-click each STM-N slot and choose Change Card. Step 5 In the Change Card dialog box, choose the new STM-N card type.

Step 6 Click OK.

Step 7 Complete the “NTP-D16 Install STM-N Cards and Connectors” procedure on page 2-7to install the new STM-N cards in both endpoints.

Step 8 Verify that the transmit signal falls within the acceptable range. See Table 2-4 on page 2-17for STM-N card transmit and receive levels.

Step 9 Complete the “DLP-D337 Install Fiber-Optic Cables for SNCP Configurations” task on page 20-33to attach the fiber to the cards. Wait for the IMPROPRMVL alarm to clear and the cards to become active.
