Ethernet Ports on the SWAN Concentrator
WAN Ports and Communications Line Interface Processors
(CLIPs)
Three CLIPs are provided on a SWAN concentrator. Each CLIP has two WAN ports
that can run different communications protocols or electrical interfaces simultaneously.
For enhanced reliability, each CLIP has access to both Ethernet ports.
Figure 1-4 shows the six WAN ports on the front panel of the SWAN concentrator.
Each WAN port has a 50-pin connector, which can support the RS-232, RS-449, X.21,
and V.35 electrical interfaces, although the 50-pin connector does not physically match
any of the connectors used for these interfaces.
HP provides four types of interface converter cables to convert the 50-pin connector
to a connector that matches your interface. Each interface converter cable type
supports, both electrically and physically, one of the supported electrical interfaces.
Four sense pins in the 50-pin connector are wired to indicate which type of interface
converter cable is attached, enabling the SWAN concentrator to know which electrical
interface is connected.
