Power Down the Node


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 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 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 16. If cards are installed, log into the node. See the "DLP-D60 Log into CTC" task on page 3-24 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-D281 Remove a Node from a Linear ADM" procedure on page 16-21, the "NTP-D213 Remove an MS-SPRing Node" procedure on page 16-9, or the "NTP-D106 Remove an SNCP Node" procedure on page 16-18. If the node is part of a Software R4.6 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 16 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 > DCC/GCC/OSC tabs and delete all regenerator DCC, LDCC, GSC, or OSC terminations:


Note In Software R4.1 the tab is labeled DCC/GCC. In Software R4.6 the tab is labeled DCC/GCC/OSC.


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

b. Click Yes.

Repeat until no regenerator SDCC or OSC terminations appear.

Step 7 For each installed STM-N or DS-N card, place 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 For each installed MSTP channel-bearing card, place all lines and channels in Out of Service status:

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

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

c. Click the Provisioning > Optical Chn > Parameters tabs.

d. Click under the Status column for each channel and choose Out of Service.

Step 9 For each installed MSTP band-bearing card, place all lines and bands in Out of Service status:

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

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

c. Click the Provisioning > Optical Band > Parameters tabs.

d. Click under the Status column for each band and choose Out of Service.

Step 10 For each installed DWDM transponder (TXP) or Muxponder (MXP) card, place all lines in Out of Service status:

a. In the card view, click the Provisioning > Line > SONET tabs if the card was provisioned for a SONET payload, or the Provisioning > Line > SDH tabs if the card was provisioned for an SDH payload.

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

Step 11 Remove all fiber connections to the cards.

Step 12 In node view, right-click an installed card and click Delete.

Step 13 Click Yes.

Step 14 After you have deleted the card, open the card ejectors and remove it from the node.

Step 15 Repeat Steps 7 through 14 for each installed card.


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


Step 16 Shut off the power from the power supply that feeds the node.

Step 17 Disconnect the node from its external fuse source.

Step 18 Store all the cards you removed and update inventory records according to local site practice.

Stop. You have completed this procedure.
