4.3 Removing and Replacing a CLIP Module
This section explains how to remove and replace the Client Layer Interface Port (CLIP) module for
protected and unprotected channels. This module is used in both the ONS 15252 Multichannel Unit
(MCU) and the ONS 15201 Single-Channel Unit (SCU).
and a protected CLIP module.
The following removal and replacement procedures assume that you are removing and replacing the
same type of CLIP module.
In applications with unprotected channels, the fiber on the B side of the CLIP is not connected to the
NAM.
Install a protected CLIP module with a NAM that has a splitting ratio of 50/50, 10/90, or 90/10. Install
an unprotected CLIP module with a NAM that has a splitting ratio of 100/0 or 0/100.
Be careful not to pull or make sharp bends in the optical fibers. Always clean and inspect MU or SC

connectors with proper tools before inserting them into the adapters.
4.3.1 Removal Instructions
The following paragraphs describe the removal procedures for CLIP modules for both protected and
unprotected channels.
Procedure: Remove the Protected Client Layer Interface Port Module
Before removing a CLIP module, you should retrieve and write down the switchmode, data rate,
protect/unprotected mode, and FDI enabled/disabled settings for the CLIP module using the ONS 15200
web-based interface Path Summary screen. The default setting for datarate is STM-16/OC-48. To modify
the settings, use the Cisco ONS 15200 Web Interface Software User Manual .
Disconnect the client-side optical fiber connectors from the CLIP module.
Step 1
Protect the fiber ends with SC dust caps.
Step 2
Plug the ports with SC dust plugs.
Step 3
Disconnect the DWDM-layer Tx-to-CLIP module optical fiber.
Step 4
Protect the connector with an MU fiber cap.
Step 5
Plug the associated MU adapter on the CLIP module front panel with an MU dust plug.
Step 6
Disconnect the DWDM receiver A-side and B-side optical fiber connectors from the CLIP module, one

at a time.
Protect the connectors with MU fiber caps.
Step 8
Plug the associated MU adapters on the CLIP module front panel with MU dust plugs.
