5.2.4.3.2 Configure Ethernet Bridge Mode via Optional Network
Processor (NP) Interface
Due to backplane limitations, the Switch supports Single-port Ethernet Bridge Mode only.
Ethernet Bridge Mode redundancy, when using SLM-5650/5650A modems equipped with the
optional Network Processor (NP) Interface, is provided by a single IP Address scheme.
Typical for each Online Modem – use the SLM-5650/5650A Front Panel menu to verify Single IP
Address Mode (make sure to press ENT to save your changes). Do these steps:
Step Task
1
Use the ◄ ► arrow keys to select the nested Select: CONFIG  Remote  EthernetConfig 
Option Card Addr Network Proc menu.
2 Verify that the AddrMode is set to Single.
Then, for the Offline Modem – use the SLM-5650/5650A Front Panel menu to verify Single IP
Address Mode (make sure to press ENT to save your changes). Do these steps:
Step Task
1
Use the ◄ ► arrow keys to select the nested Select: CONFIG  Remote  EthernetConfig  Option
Card Addr  Network Proc menu.
2 Set the Traffic IP Address of the Online Modem only.
3 Verify that the Traffic IP Address also appears on the Offline Modem.
In Ethernet Bridge Mode, the Switch keeps the Online Modem’s active Ethernet Port turned on,
while the Offline Modem’s active Ethernet Port is turned off. The traffic IP Address is only
accessible on the Online Modem.
Furthermore, the parameter backup mechanism is unsupported in Ethernet Bridge Mode. You
must therefore make sure that all parameters match in the Online and Offline modems.
See Chapter 5. FRONT PANEL OPERATION in the SLM-5650 or SLM-5650A Installation
and Operation Manual for detailed information about using the modem front panel
menus.
5.2.4.3.3 Configure Ethernet Bridge Mode via Optional GbE Interface
The Switch supports Single-port Ethernet Bridge Mode only due to backplane limitations.
Ethernet Bridge Mode redundancy, when using SLM-5650/5650 modems equipped with the
optional 10/100/1000 Base-T (GbE) Interface, is provided by a Single IP Address scheme.
You must configure the SLM-5650/5650A for Ethernet Bridge Mode redundancy. Typical for
each modem – use the SLM-5650/5650A Front Panel menu to enter a unique IP Address for the
optional 10/100/1000 Base-T (GbE) Interface card that is on the same subnet. Make sure to
press ENT to save your changes:
Select: CONFIG Mode  Interface  Gigabit Ethernet
