Client Layer Interface Port Module
Loosen the CLIP module mounting thumbscrews.
Step 10
Carefully remove the CLIP module from the ONS 15252 MCU or the ONS 15201 SCU. Make sure that
Step 11
the optical fibers are not harmed in the process.
Install a CLIP module dummy front where the CLIP module was removed from the ONS 15252 MCU
Step 12
or the ONS 15201 SCU unit, unless you will replace it immediately.
Procedure: Remove an Unprotected 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, see 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 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 optical fiber connector from the CLIP module.
Step 7
Protect the connector with an SC fiber cap.
Step 8
Plug the associated MU adapter on the CLIP module front panel with an MU dust plug.
Step 9
Loosen the CLIP module mounting thumbscrews.
Step 10
Carefully remove the CLIP module from the ONS 15252 MCU or the ONS 15201 SCU. Ensure that the
Step 11
optical fibers are not harmed in the process.

Step 12
or the ONS 15201 SCU unit, unless you will replace it immediately.
4.3.2 Replacement Instructions
The following paragraphs describe the replacement procedures for CLIP modules for both protected and
unprotected channels.
Procedure: Replace the Protected Client Layer Interface Port Module
Remove the CLIP module dummy front from the ONS 15252 MCU or ONS 15201 SCU, if necessary.
Step 1
Align the CLIP module with the CLIP module slot.
Step 2
Carefully insert the CLIP module into the slot. Be sure that the backplane connector and the CLIP
Step 3
module connector are correctly mated and that no optical fibers are damaged in the process.
