Removing a CWDM OADM or a CWDM OMUX

CWDM OADMs and CWDM OMUXs are passive devices that require no power for their operation. You can remove them from the optical shelf (Figure 15) after disconnecting them from your network.

To remove a CWDM OADM or a CWDM OMUX plug-in module from the optical shelf:

1Disconnect the network cabling from the multiplexer.

2Loosen the captive screws on both sides of the module.

3To release the module, gently pull on both screws at the same time.

4Slide the module out of the shelf.
