Power Down the Node
This chapter explains how to power down a Cisco ONS 15327 node and stop all node activity.
NTP-B114 Power Down the ONS 15327
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 will be lost if you delete and recreate circuits that passed through a working node.
Caution Always use the supplied ESD wristband when working with the Cisco ONS 15327. Plug the wristband into the ESD jack located on the fan-tray assembly or on the lower right outside edge of the shelf on the NEBS 3 shelf assembly. To access the ESD plug on the NEBS 3 shelf assembly, open the front door of the Cisco ONS 15327. The front door is grounded to prevent electrical shock.
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 working network, log out of the node and complete the "B213 Remove a BLSR Node" procedure, or the "B106 Remove a Path Protection Node" procedure. If the node is part of a Software R4.7 Multi-Service Transport Platform (MSTP) configuration, consult your network administrator. 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.
Step 4 In node view, click the Circuits tab and verify that no circuits are displayed, then proceed to Step 5. If circuits are displayed, delete all the circuits that originate or terminate in the node, as follows:
a. Click the circuits that need to be deleted and click Delete.
b. Click Yes.
Repeat until no circuits are displayed.
Step 5 Complete the "B203 Modify or Delete 1+1 Card Protection Settings" procedure to delete any optical protection group. You cannot delete the default electrical protection group, XTCPROTGRP.
Repeat until all protection groups are deleted.
Step 6 Complete the "DLP-B19 Delete a Section DCC Termination" task for all cards. Repeat until no SDCC terminations appear.
Step 7 Complete the "DLP-B230 Change a Circuit State" task to change all ports in each card to out of service (OOS).
Step 8 Remove all fiber connections to the cards.
Step 9 Complete the "DLP-B320 Delete a Card" task for all traffic cards. You cannot delete an XTC card.
Step 10 Click Yes.
Step 11 After you have deleted the card, open the card ejectors and remove it from the node.
Step 12 Open the ejectors and remove the XTC card from the node. Repeat for the second XTC.
Step 13 Shut off the power from the power supply that feeds the node.
Step 14 Disconnect the node from its external fuse source.
Step 15 Store all the cards you removed and update inventory records according to local site practice.
Stop. You have completed this procedure.
