APPENDIX C
Cascading with IP Switching.
To fully utilize the GbE feed and the capacity of the NSG, it is best to use
3xNSG 9116 units cascaded with IP switching. Chain two different NSG
9116 units to another NSG 9116 unit. Each of the two units receives a
different GbE input stream and draws the services intended for it. Each
unit passes on the traffic to a different GbE port of a third NSG unit so a
total of one GbE is used.
The IP switching option supports the cascading single channels using two
different GbE channels with no channel redundancy.
To use the IP switching option:
1. Connect the Switch Tx to the GbE1 Rx connector on the first NSG.
2. Connect the first NSG GbE1 Tx to the second NSG GbE1 Rx.
3. Connect second NSG GbE1 Tx to a Rx connector of the switch.
4. Connect the Switch Tx to the GbE1 Rx connector on the third NSG.
5. Connect the third NSG GbE1 Tx to the GbE2 Rx of the second NSG.
6. Connect the second NSG GbE2 Tx to a Rx connector of the switch.
7. Using the Web client, configure the second NSG to operate in the IP
Switching mode and configure its input ports to have different IP
addresses. For further details, refer to the Web client online help.
The following figure illustrates the IP switching connections:
