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 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 CiscoONS15600SDH. Plug the wristband into the ESD jack located on the fan-tray assembly or on the lower-left outside edge of the shelf on the shelf assembly.
Step1 Identify the node that you want to power down. If no cards are installed, go to Step 15. If cards are installed, complete the "DLP-F36 Log into CTC" task.
Step2 From the View menu, choose Go To Network View .
Step3 Verify that the node is not connected to a working network:
a. If the node is part of a subnetwork connection protection (SNCP) configuration, log out of the node and complete the "NTP-F86 Remove an SNCP Node" procedure . Continue with Step 4 .
b. If the node is part of a multiplex section-shared protection ring (MS-SPRing), log out of the node and complete the "NTP-F84 Remove an MS-SPRing Node" procedure . Continue with Step 4 .
c. If the node is part of a point-to-point or linear ADM, go to Step 6 .
d. 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 15.
Step4 From the View menu, choose Go To Home View .
Step5 Click the Circuits tab and verify that no circuits appear, then proceed to Step6. If circuits appear, delete all the circuits that originate or terminate in the node:
a. Click the circuit that needs to be deleted and click Delete .
b. Click Yes .
Repeat until no circuits are present. For more information, see the "DLP-E97 Delete Circuits" task .
Step6 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 present. For more information, see the "DLP-F117 Delete a 1+1 Protection Group" task .
Step7 Click the Provisioning > DCC/GCC tabs and delete all regenerator section-data communications channel (RS-DCC) terminations:
a. Click the RS-DCC Termination that needs to be deleted and click Delete .
b. Click Yes .
Repeat until no RS-DCC terminations are present. For more information, see the "NTP-F70 Delete an RS-DCC Termination" procedure .
Step8 For each installed card, put all ports in Out of Service status:
a. Double-click a card to display card view.
a. Click the Provisioning > MS tabs.
b. Click in the State column for each port and choose Out of Service .
c. Click Apply .
For more information, see the "NTP-F76 Modify Line and Status Thresholds for Optical Ports" procedure .
Step9 Remove all fiber connections to the cards. For more information about fiber cabling, see the "NTP-F16 Install the Fiber-Optic Cables" procedure.
Step10 From the View menu, choose Go To Home View to return to node view.
Step11 Right-click an installed card and click Delete .
You cannot delete a card if any of the following conditions apply:
•The card is part of a protection group.
•The card has circuits.
•The card is being used for timing.
•The card has a SDH DCC termination.
Step12 Click Yes .
For more information about card deletion, see the "DLP-F22 Delete a Card from CTC" task .
Step13 After you have deleted the card, open the card ejectors and remove it from the node.
Step14 Repeat Steps 8 through 13 for each installed card.
Step15 Shut off the power from the power supply that feeds the node. For more information about power issues, see the "NTP-F5 Install the Bay Power and Ground" procedure.
Step16 Disconnect the node from its external fuse source.
Step17 Store all cards and update inventory records according to local site practice.
Stop. You have completed this procedure.
