DLP-D296 Perform a Manual Span Upgrade on a 1+1 Protection Group

Purpose	This task upgrades a 1+1 protection group span. To downgrade an
	optical span, repeat this task but choose a lower-rate card in Step 6.
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

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 Initiate a Force switch on the ports you will upgrade, beginning with the protect port:

Note If the switching mode is bidirectional in the 1+1 protection group, apply the Force command to only one end of the span. If the Force command is applied to both ends when the switching mode is bidirectional, it will cause a switch of more than 50 ms in duration.

a.In node view, click the Maintenance > Protection tabs.

b.Choose the protection group from the Protection Groups area. In the Selected Group area, the working and protect spans appear.

c.In the Selected Group area, click the protect STM-N port.

d.In Switch Commands, choose Force.

e.Click Yes in the confirmation dialog box.

FORCE-SWITCH-TO-WORKING appears next to the forced span.

Step 2 Repeat Step 1 for each port you will upgrade.

Step 3 Remove the fiber from both ends of the span and ensure that traffic is still running.

Step 4 Remove the STM-N cards from both span endpoints.

Step 5 At both ends of the span, in node view, right-click the STM-N slot and choose Change Card.

	Step 6	In the Change Card dialog box, choose the new STM-N card type.
	Step 7	Click OK.
	Step 8	Complete the “NTP-D16 Install STM-N Cards and Connectors” procedure on page 2-7to install the new
