Cisco ONS 15600 Procedure Guide, Releases 9.1 and 9.2.1

Power Down the Node

---

This chapter explains how to power down a node and stop all node activity on the Cisco ONS 15600.

NTP-E80 Power Down the ONS 15600

Purpose	This procedure stops all node activity.
Tools/Equipment	None
Prerequisite Procedures	None
Required/As Needed	As needed
Onsite/Remote	Onsite
Security Level	For software steps, the Provisioning level or higher is required. For hardware steps, any level is allowed.

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

---

Caution The following procedure is designed to minimize traffic outages when powering down nodes, but traffic is lost if you delete and recreate circuits that passed through a working node.

---

---

Note Always use the supplied ESD wristband when working with the ONS 15600. For detailed instructions on how to wear the ESD wristband, refer to the Cisco ONS Electrostatic Discharge (ESD) and Grounding Guide.

Step 1 Identify the node that you want to power down. If no cards are installed, go to Step 13. If cards are installed, complete the "DLP-E26 Log into CTC" task.

Step 2 In node view, choose Go to Network View from the View menu.

Step 3 Verify that the node is not connected to a network:

a. If the node is part of a a working network, log out of the node and complete the "NTP-E123 Remove a Path Protection Node" procedure, or the "NTP-E169 Remove a BLSR Node" procedure. Continue with Step 4.

b. If the node is not connected to a working network and the current configurations are no longer required, proceed to Step 4.

---

Note You can save the current configurations by skipping Steps 4 through 11.

---

Step 4 In node view, click the Circuits tab and verify that no circuits appear, then proceed to Step 5. If circuits appear, complete the "DLP-E163 Delete Circuits" task. Repeat until no circuits appear.

Step 5 Complete the "DLP-E87 Delete a 1+1 Protection Group" task to delete any optical protection group. Repeat until no protection groups are present.

Step 6 Complete the "NTP-E128 Modify or Delete Communications Channel Terminations" procedure for all ports. Repeat until no SDCC or LDCC terminations exist.

Step 7 Complete the "DLP-E115 Change the Service State for a Port" task to change all ports to the Out-of-Service and Management,Disabled (OOS-MA,DSBLD) service state.

Step 8 Remove all fiber connections to the cards.

Step 9 Complete the "DLP-E276 Remove an SFP/XFP" task if there are any SFPs or XFPs installed.

Warning Class 1 laser product. Statement 1008

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Step 10 In node view, right-click an installed card and choose Delete Card.

Step 11 Click Yes.

Step 12 After you have deleted the cards, open the card ejectors for each card and remove each card from the node.

Step 13 Shut off the power from the power supply that feeds the node. For more information about power issues, see the "NTP-E4 Install the Bay Power and Ground" procedure.

Step 14 Disconnect the node from its external fuse source.

Step 15 Store all of the cards you removed and update inventory records according to local site practice.

Stop. You have completed this procedure.
