WAN Adapter Module Placement Considerations
When installing WAN adapter modules in the Passport 5430 Module slots, note
the following:
the following:
•
Each WAN adapter module you install is automatically assigned a circuit,
even if the WAN adapter module has not been configured. This prevents
disruption of active circuits if you reconfigure the the module at a later time.

•
ISDN BRI adapter modules can use two circuits (one for each of the 2 B
channels).
channels).
•
You can configure a total of 4 circuits.
•
Circuit allocations are prioritized according to which Module slot is being
used by the WAN adapter modules. Module slot 3 has priority over Module
slot 4, and Module slot 4 has priority over Module slot 5.
used by the WAN adapter modules. Module slot 3 has priority over Module
slot 4, and Module slot 4 has priority over Module slot 5.
•
When there are more than the 4 possible circuits to be configured, for example
if there are 2 ISDN BRI adapter modules and a serial adapter module (5
circuits in all), circuit allocation becomes an issue.
