Mocomtech CRS-300 operation manual Step Procedure

CRS-300 1:10 Redundancy Switch	Revision 16
Modem, RMI/TMI, and Switch Configuration	MN/CRS300.IOM

5.2.4.4Switch to SLM-5650/5650A Redundancy Configuration

5.2.4.4.1TTL (Switch) Configuration (For All Traffic Data Types)

The CRS-300 communicates to the Redundant and Traffic modems via a serial TTL bus contained within the HD-15 “J9 Auxiliary” connector on the modem’s rear panel. An HD-15M to HD-15F Control Cable connects each modem to the CRS-300.

To use 1:N redundancy, the SLM-5650/5650A must have communications configured to TTL (Switch) in order to communicate with the CRS-300. To set the serial interface:

Step Procedure

1From the SLM-5650/5650A front panel menu, navigate to Config: Remote Æ SerialConfig.

2Set Interface to TTL (SWITCH).

3Set Format to 8N1.

4Set Baudrate to 9600 Baud.

5Verify that Traffic Modem is ONLINE and the Redundant Modem is OFFLINE.

For detailed information on using the front panel menus, see Chapter 5. FRONT PANEL OPERATION in the SLM-5650or SLM-5650A Installation and Operation Manual.

5.2.4.4.2Ethernet Bridge Mode Configuration via Optional Network Processor (NP) Interface

Due to backplane limitations, the CRS-300 can support 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.

To verify Single IP Address Mode on the Online Modem:

Step Procedure

1From the SLM-5650A front panel, navigate to Config: Remote Æ EthernetConfig Æ Option Card Addr ÆNetwork Proc.

2Verify that the Mode appears as Single.

To verify Single IP Address Mode on the Offline Modem:

Step Procedure

1From the SLM-5650A front panel, navigate to Config: Remote Æ EthernetConfig Æ Option Card Addr ÆNetwork Proc.

2Set 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 CRS-300 will keep 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.
