This chapter explains how to power down a node and stop all node activity on the Cisco ONS 15454 SDH.

NTP-D114 Power Down the Node

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, 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 will be lost if you delete and recreate circuits that passed through a working node.


Note Always use the supplied ESD wristband when working with the Cisco ONS 15454 SDH. Plug the wristband into the ESD jack located on the fan-tray assembly or on the lower right outside edge of the shelf assembly. To access the ESD plug on the shelf assembly, open the front door of the Cisco ONS 15454 SDH. The front door is grounded to prevent electrical shock.



Step 1 Identify the node that you want to power down. If no cards are installed, go to Step 13. If cards are installed, log into the node. See the "DLP-D60 Log into CTC" task for instructions.

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

Step 3 In network view, 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 "NTP-D322 Remove an In-Service Node from a Linear ADM" procedure, the "NTP-D213 Remove an MS-SPRing Node" procedure, or the "NTP-D106 Remove an SNCP Node" procedure. If the node is part of a Software R6.0 MSTP configuration, consult your network administrator. (Linear configurations will be deleted in Step 5.) Continue with the next step.

b. If the node is not connected to a working network and the current configurations are no longer required, continue with the next step.


Note Current configurations will be saved if Steps 4 through 13 are skipped.


Step 4 In node view, click the Circuits tab and verify that no circuits are displayed, then proceed to Step 5. If circuits appear, 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 appear.

Step 5 In node view, click the Provisioning > Protection tabs and delete all protection groups:

a. Click the protection group that needs to be deleted and click Delete.

b. Click Yes.

Repeat until no protection groups appear.

Step 6 In node view, click the Provisioning > Comm Channels tabs and delete all RS-DCC, MS-DCC, GCC, or OSC terminations:

a. Click the regenerator section data communications channel (RS-DCC), multiplex section data communications channel (MS-DCC), generic communications channel (GCC), or optical service channel (OSC) termination that needs to be deleted and click Delete.

b. Click Yes.

Repeat until no RS-DCC, MS-DCC, GCC, or OSC terminations are present.


Note Before deleting the OSC termination, make sure the Ring ID is deleted. Click the Provisioning > Comm Channels > OSC tabs. Select the Ring ID and click Delete.


Step 7 For each installed STM-N or DS-N card, make sure all ports are in Locked-enabled,disabled service state:

a. In card view, click the Provisioning > Line tabs.

b. Click under the Status column for each port and choose Locked,disabled.

Step 8 Remove all fiber connections to the cards.

Step 9 In node view, right-click an installed card and click Delete.

Step 10 Click Yes.

Step 11 After you have deleted the card, open the card ejectors and remove it from the node.

Step 12 Repeat Steps 7 through 11 for each installed card.


Note You cannot delete a TCC2/TCC2P card in CTC. Physically remove it after all the other cards have been deleted and removed.


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.
