Power Down a Node
This chapter explains how to power down a node and stop all node activity on the Cisco ONS 15454 ANSI or ETSI.
Note
The CTC views referenced in this chapter depend on the ONS 15454 mode. For more information about CTC views, see Appendix A, “CTC Information and Shortcuts.”
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
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 17. If cards are installed, log into the node. See the G46 Log into CTC for instructions.
Step 2 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 Software R4.7 or later dense wavelength division multiplexing (DWDM) configuration, see the G130 Remove a DWDM Node 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 Before the power-down of a DWDM node, the fiber spans connected around it must be disconnected from the network. This is to prevent the accidental disconnection of wavelengths that pass through the shelf. A good indication that the shelf has been disconnected from the network is optical service channel (OSC) alarms, or no OSC channels provisioned.
Note Current configurations will be saved if Steps 4 to 17 are skipped.
Step 4 In node view (single-shelf mode) or multishelf view (multishelf mode), click the Circuits tab and verify that no circuits appear, then proceed to Step 5. If circuits appear, delete all the circuits that originate or terminate in the node. Complete the G106 Delete Optical Channel Network Connections, the G347 Delete Optical Channel Client Connections, or the G112 Delete Overhead Circuits as needed.
Note When deleting circuits from a node, make sure that the node is not connected to any network.
Step 5 In node view (single-shelf mode) or shelf view (multishelf mode), click the Provisioning > Protection tabs and delete all protection groups:
a. Click the protection group that needs to be deleted and click Delete.
Repeat until no protection groups appear.
Step 6 In node view (single-shelf mode) or multishelf view (multishelf mode), click the Provisioning > Comm Channels tabs and delete all communications channel terminations:
a. Click the section data communications channel (SDCC), line data communications channel (LDCC), generic communications channel (GCC), or OSC termination that needs to be deleted and click Delete.
Repeat until no SDCC, LDCC, GCC, or OSC terminations are present.
Step 7 Before deleting any installed DWDM cards, the optical patch cords and the optical sides have to be deleted. In node view (single-shelf mode) or multishelf view (multishelf mode), click Provisioning > WDM-ANS > Internal Patchcords tabs.
a. Select all the connections and click Delete.
Step 8 In node view (single-shelf mode) or multishelf view (multishelf mode), click Provisioning > WDM-ANS > Optical Side tabs.
a. Select all the connections and click Delete.
Step 9 For each installed channel-bearing card (AD-1C-xx.x, AD-2C-xx.x, and AD-4C-xx.x, where xx.x refers to the specific wavelengths), make sure all lines and bands are not in IS-NR (ANSI) or Unlocked-Enabled (ETSI) service state:
a. In card view, click the Provisioning > Optical Line > Parameters tabs.
b. In the Admin State column for each line, make sure that the default state IS, AINS (ANSI) or Unlocked,automaticInservice (ETSI) is selected.
c. Click the Provisioning > Optical Chn > Parameters tabs.
d. In the Admin State column for each line, make sure that the default state IS, AINS (ANSI) or Unlocked,automaticInservice (ETSI) is selected.
Step 10 For each installed DWDM band-bearing card (AD-1B-xx.x and AD-4B-xx.x, where xx.x refers to the specific wavelengths), make sure all lines and bands are not in the IS-NR (ANSI) or Unlocked-Enabled (ETSI) service state:
a. In card view, click the Provisioning > Optical Line > Parameters tabs.
b. In the Admin State column for each line, make sure that the default state IS, AINS (ANSI) or Unlocked,automaticInservice (ETSI) is selected.
c. Click the Provisioning > Optical Band > Parameters tabs.
d. In the Admin State column for each line, make sure that the default state IS, AINS (ANSI) or Unlocked,automaticInservice (ETSI) is selected.
Step 11 For each installed transponder (TXP), muxponder (MXP), multiplexer, demultiplexer, amplifier, OSC-CSM, OSCM, or wavelength switch card (32MUX-O, 32DMX-0, 32DMX, 32WSS, 4MD-xx.x, 40-WSS-C, 40-WSS-CE, 40-WXC-C, 40-DMX-C, 40-DMX-CE, 40-MUX-C, OPT-BST, OPT-PRE, TXP_MR_10G, TXP_MR_10E, TXP_MR_2.5G, TXPP_MR_2.5G, MXP_2.5G_10G, MXP_2.5G_10E, MXP_MR_2.5G, MXPP_MR_2.5G, GE_XP, 10GE_XP, GE_XPE, 10GE_XPE, or ADM-10G), make sure all lines are not in the IS-NR (ANSI) or Unlocked-enabled (ETSI) service state:
a. In card view, click the appropriate tab depending on the card:
- For MXP_2.5G, MXP_2.5G_10G, TXP_MR_10G, TXP_MR_10E cards, 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.
- For TXP_MR_2.5G, TXPP_MR_2.5G, and MXPP_MR_2.5G cards, click the Provisioning > Line > SONET tabs.
- For MXP_2.5G_10E cards, click the Provisioning > Line > Trunk tabs.
- For MXP_MR_2.5G cards, click the Provisioning > Line > Client tabs.
- For ADM-10G cards, click the Provisioning > Line > Ports tabs.
- For 32MUX-O, 32DMX-0, 32DMX, 32WSS, 40MUX, 40DMUX-C, OPT-BST, OPT-PRE cards, click the Provisioning > Optical Line > Parameters tabs.

- For 4MD-xx.x cards, click the Provisioning > Optical Band > Parameters tabs.
- For GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE cards, click the Provisioning > Ether Ports > Ports tabs.
- For OPT-BST and OPT-PRE cards, click the Provisioning > Optical Ampli Line > Parameters tabs.
- For OSC-CSM and OSCM cards, click the Provisioning > Optical Line > Parameters tabs.
- For ADM_10G cards, click the Provisioning > Line > Ports tabs.
b. In the Admin State column for each line, make sure that the default state IS, AINS (ANSI) or Unlocked,automaticInservice (ETSI) is selected.
c. Repeat Steps a and b for each installed DWDM card.
Note Ports are put in service when circuits are provisioned, and put out of service when circuits are deleted. When circuits are deleted the Admin State displays as IS, AINS (ANSI) or Unlocked,automaticInservice (ETSI) and the Service State displays OOS-AU,AINS (ANSI) or Unlocked-disabled,automaticInService (ETSI).
Step 12 Remove all fiber connections to the cards.
Step 13 In node view (single-shelf mode) or shelf view (multishelf mode), right-click an installed card and click Delete.
Step 15 After you have deleted the card, open the card ejectors and remove it from the node.
Step 16 Repeat Step 12 through Step 15 for each installed card.
Note You cannot delete a TCC2 or TCC2P card in Cisco Transport Controller (CTC). Physically remove it after all the other cards have been deleted and removed.
Step 17 Shut off the power from the power supply that feeds the node.
Step 18 Disconnect the node from its external fuse source.
Step 19 Store all of the cards that you removed and update inventory records according to local site practice.
Stop. You have completed this procedure.
