Turn Up a DWDM Node

This chapter explains how to provision a single Cisco ONS 15454 dense wavelength division multiplexing (DWDM) node and turn it up for service, including node name, date and time, timing references, network attributes such as IP address and default router, users and user security, and DWDM parameters.

Note The procedures and tasks in this chapter apply to DWDM (Software Release 4.5) nodes only.

Note To provision an ONS 15454 for DWDM, you must have a DWDM network planning application, such as Cisco MetroPlanner. Cisco MetroPlanner designs the entire network based on your traffic flow and physical topology. The design includes an ONS 15454 shelf plan listing the DWDM cards that need to be installed for each node in the DWDM network. MetroPlanner provides a configuration file that you can import into the node to set its power and attenuation levels automatically. For information about Cisco MetroPlanner, contact your Cisco account representative.

Before You Begin

Complete the following procedures and tasks before you begin DWDM node turn up:

•In "Install the Shelf and Backplane Cable," complete all procedures.

•In "Install Cards and Fiber-Optic Cable," complete the "DLP-A36 Install the TCC+/TCC2 Cards" task.

•In "Connect the PC and Log into the GUI," complete all procedures.

•In "Turn Up Node," complete all procedures.

This section lists the procedures (NTPs) that you need to complete to turn up a DWDM node. Turn to a procedure for applicable tasks (DLPs).

1. A221 Verify TCC2 Installation—Complete this procedure first.

2. Using your DWDM shelf layout plan, complete the following procedures:

–A242 Install the DWDM Cards

–A243 Install the DWDM Dispersion Compensating Cards, as needed

–A244 Install Fiber-Optic Cables on DWDM Cards

3. A222 Provision the DWDM Node—Complete this procedure last.

NTP-A221 Verify TCC2 Installation

Purpose

This procedure verifies that the ONS 15454 node has TCC2 cards installed and is ready for DWDM provisioning.

Step 1 Verify that two TCC2 cards are installed in Slots 7 and 11.

Step 2 Verify that the green ACT (active) LED is illuminated on one TCC2 and the amber STBY (standby) LED is illuminated on the second TCC2.

Note If the TCC2s are not installed, or their LEDs are not illuminated as described, do not proceed. Repeat the "DLP-A36 Install the TCC+/TCC2 Cards" task, or refer to the Cisco ONS 15454 Troubleshooting Guide to resolve installation problems before proceeding to the next procedure.

Step 3 Verify that the software release shown on the LCD matches the software release indicated in your site plan. If the release does not match, perform one of the following procedures:

•Perform a software upgrade using a Cisco ONS 15454 software CD. Refer to the Cisco ONS 15454 Software Upgrade Guide for instructions.

•Replace the TCC+/TCC2 cards with cards containing the correct release. Refer to the Cisco ONS 15454 Troubleshooting Guide for replacement procedures.

Stop. You have completed this procedure.

NTP-A222 Provision the DWDM Node

Purpose

This procedure sets the network and system settings and provisions the node power levels.

Tools/Equipment

Step 1 Complete the "DLP-A60 Log into CTC" task at the DWDM node you want to provision.

Step 2 Click the Connections tab, then click the Calculate Connections button.

Step 3 Verify that every connection matches the connections specified by your DWDM design plan. If a connection is not correct:

a. Delete the connection. See the "DLP-A405 Delete a DWDM Connection" task.

b. Uninstall the fibers from the incorrect slot/card/port.

c. Connect the fiber to the correct slot/card/port.

Step 4 Perform one of the following tasks:

•If you have a Cisco MetroPlanner configuration file, complete the "DLP-A400 Import a Cisco MetroPlanner Configuration File" task.

•If you need to provision the node manually, complete one of the following tasks as appropriate:

–A401 Provision DWDM Hub Node Settings.

–A402 Provision DWDM Terminal Node Settings.

–A403 Provision DWDM OADM Node Settings.

–A404 Provision DWDM Line Node Settings.

d. Create a new connection. See the "DLP-A406 Create a DWDM Connection" task.

Step 5 Click the Services tab. Click Launch ANS. Automatic Node Setup (ANS) adjusts the values of the variable optical attenuators (VOAs) to equalize the per-channel power at the amplifier level.

Step 6 Complete the "DLP-A407 Verify OSCM and OSC-CSM Transmit Power" task.

Stop. You have completed this procedure.

Step 3 From the ALS Command drop-down menu, choose Manual Start.

Step 4 Click the Provisioning > Optical Line tabs.

Step 5 For the TX (transmit) port entry, verify that the value in the Power column falls within the following ranges:

•For OSCM cards installed on nodes set to Control Gain, the power should be -5dBm.

•For OSC-CSM card installed on nodes set to Control Gain, the power should be a minimum of -6 dBm on OADM nodes.

•For OSC-CSM cards installed on nodes configured as a passive or active OADM nodes, the power level depends on the Pout OADM Stage power level on the WDM-ANS > Provisioning tab:

–If the Pout OADM Stage value is less than -6.5 dBm +/- 0.5 dBm, the OSC-CSM power should be equal to that power.

–If the Pout OADM Stage value is greater than -6.5 dBm +/- 0.5 dBm, the OSC-CSM power should be -6.5 dBm +/- 0.5 dBm.

Step 6 If the OSCM or OSC-CSM power levels are not within the ranges specified in Step 5, complete the following steps:

a. Click the Maintenance > ALS tabs. Verify that the ALS Command is set to OSRI off.

b. In the ALS Command area, choose Manual Restart and click Apply.
