DLP- D294 Perform a Manual Span Upgrade on a Four-Fiber MS-SPRing

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 on the upgraded span. See the “DLP-D194 Clear an MS-SPRing Force Ring Switch” task on page 18-82.

Step 11 Repeat this task for each span in the MS-SPRing. When you are done with all of the spans, the upgrade is complete.

Step 12 Return to your originating procedure (NTP).

DLP-D294 Perform a Manual Span Upgrade on a Four-Fiber MS-SPRing

Purpose	This task upgrades a four-fiber MS-SPRing span to a higher optical rate.
	Repeat the task to upgrade each span in the ring to the higher optical
	rate. To downgrade an optical span in a four-fiber MS-SPRing, 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

	Note All spans connecting the nodes in an MS-SPRing must be upgraded before the bandwidth is available.
	Note If you are upgrading a span on an MS-SPRing, a MSSP-OSYNC alarm will appear in the alarms list.
		Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for information about this alarm.
	Step 1 Apply a Force switch to both span endpoints (nodes) on the span that you will upgrade first. See the
		“DLP-D303 Initiate an MS-SPRing Force Ring Switch” task on page 20-3.
	Step 2 Remove the fiber from both working and protect cards at both span endpoints (nodes) and ensure that
		traffic is still running.
	Step 3 Remove the STM-N cards from both endpoints.
	Step 4	For both ends of the span endpoints, 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.
