Step 4: Connecting the Interface Converter Cables

to the WAN Ports

This figure shows two SWAN concentrators (#S01 and #S02) connected to port A on

G4SA G11123 and to port A on G4SA G11124 using Ethernet switches 3 and 4, which

are cascaded off Ethernet switches 1 and 2. The SWAN concentrator can have a

maximum of four Ethernet switches between itself and the NonStop system.

Step 4: Connecting the Interface Converter Cables to the WAN

Ports

Each of the 50-pin WAN port connectors supports the RS-232, RS-449, X.21, and V.35

electrical interfaces, but none physically matches any of the connectors used for these

interfaces. Use an interface converter cable to convert from the 50-pin connector to a

connector that matches the chosen interface. The interface converter cables are 10

feet (3.3 meters) long. There are four different interface converter cables, each one

supporting a different interface.
