SWAN 2 Concentrator Configurations
The SWAN concentrator configuration entities are the same for SWAN and SWAN 2
(see Tabl e 2-6 on page 2-11).
The SCF subsystem allows you to configure 3600 lines using any configuration of
SWAN and SWAN2 concentrators.
Table 2-14 assumes 6 CLIPs per ADAPTER for the SWAN 2 concentrator and shows
the maximum configurations allowed.
For a SWAN 2 concentrator, if all six CLIPS are configured for each SWAN 2
concentrator, you can configure a maximum of 600 SWAN concentrators. But if only
one CLIP is configured for each SWAN2 concentrator, you can configure a maximum
of 3600 entities.
The default memory allocation of WANMGR allows configuration of approximately 350
SWAN 2 concentrators. To allocate more memory, use the STARTUPMSG attribute of
the WANMGR startup configuration (For more information, see Example 2-1).
In Example 2-1, specifying 8192 datapages provides 8 megabytes memory to
WANMGR, which allows the configuration of approximately 750 to 800 SWAN 2
concentrators.
For more information about installing a SWAN 2 concentrator, see SWAN 2
Concentrator Installation and Support Guide.
