5. In the web client configure the appropriate GbE channel.
The following figure illustrates the cascaded connections.
Cascading Redundant Channels
The NSG family also supports GbE channel redundancy for cascaded
NSG devices. Cascading redundant channels is recommended when
using three NSG 9108 units.
To add a connection for the redundant GbE channel:
1. Connect the first GbE channel as described in “Cascading Single
Channels” on page 59 , steps one and two.
2. Connect the Switch 2 Tx of the GbE2 Rx connector on the last NSG in
the chain.
Note: The two channels run in opposite directions for maximum
protection. If an NSG in the middle of the chain fails, then units
downstream from the failed device can switch to the redundant
channel and continue to operate.
3. Connect the NSG GbE2 Tx on the last NSG to the GbE2 Rx on the
next-to-last NSG in the chain.
4. Continue chaining in this direction until you reach the first NSG.
5. Connect the last NSG Tx to Switch 2 Rx and select the Last in Chain
option from the web client.
