Power Down the Node


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


Note Except where noted, this procedure applies to both DWDM (Software Release 4.5) and non-DWDM (Software R4.1 and earlier) nodes.


NTP-A114 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 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.



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. 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 15454. 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-A60 Log into CTC" task for instructions.

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 "A213 Remove a BLSR Node" procedure, the "A106 Remove a Path Protection Node" procedure, or, if the node is part of a Software R4.5 DWDM 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.


Note Current configurations will be saved if Steps 4-13 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 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 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 are displayed.

Step 6 In node view, click the Provisioning > SONET DCC/GCC/OSC tabs and delete all SDCC or OSC terminations:

a. Click the SDCC or OSC termination that needs to be deleted and click Delete.

b. Click Yes.

Repeat until no SDCC or OSC terminations are present.


Note In Software R4.1, the tab is labeled SONET DCC/GCC. In Software R4.5, the tab is labeled SONET DCC/GCC/OSC.


Step 7 For each installed card, put all ports in Out of Service status:

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

b. Click under the Status column for each port and choose Out of Service.

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 Step 7 through 11 for each installed card.


Note You cannot delete a TCC+ or TCC2 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.
