64 Connecting a DWDM

APPENDIX C

Connecting a DWDM

If your network includes Dense Wavelength Division Multiplexing 
(DWDM), add the DWDM unit in between the switch and the NSG. The 
following example shows a cascaded DWDM setup with redundancy, but 
you could include a DWDM in a non-cascaded or non-redundant 
configuration.

To set up redundant GbE channels with a DWDM:

1.

Connect the first Tx connector on the demultiplexing module of the 
DWDM to the GbE1 Rx connector on the first NSG in the chain.

2.

Connect the NSG GbE1 Tx to the next NSG GbE1 Rx.

Continue chaining until you reach the last NSG in the chain.

3.

Connect the second Tx connector on the demultiplexing module of 
the DWDM to the GbE2 Rx connector on the last NSG in the chain.

4.

Connect the NSG GbE2 Tx on the last NSG to the GbE2 Rx on the 
next-to-last NSG in the chain.

5.

Continue chaining in this direction until you reach the first NSG.

The following figures shows the connections for cascaded NSGs with 
a DWDM and redundant channels.

Note: 

The following diagram illustrates typical 9100 NSG devices 

cascading configuration.
