Upgrading to a SWAN 2
Concentrator
This section describes considerations when upgrading to a SWAN 2 concentrator. It is
intended for system managers who are planning to include a SWAN 2 concentrator in
their existing configuration.
WAN Subsystem Configuration Changes
Starting with the G06.15 RVU and later RVUs, you can add a SWAN 2 concentrator to
your existing WAN subsystem configuration. The SWAN 2 concentrator:
•
Provides the same WAN functionality for each supported protocol as a SWAN
concentrator and coexists in a subnet with a SWAN concentrator.
•
Supports NonStop software products.
•
Supports the same I/O processes (IOPs) as the SWAN concentrator. For best
results, make sure you install the most recent unrestricted SPRs.
•
Uses different versions of the data link control (DLC) tasks depending on the
SWAN concentrator type (see Table 6-5 on page 6-47 and Table 6-6 on
page 6-48).
The G06.15 or later RVUs of these products support the SWAN 2 concentrator:
•
OSM
•
TSM
•
WAN Wizard Pro
•
SWAN Tools
For more information on supported protocol information, see the G06.nn Software
Installation and Upgrade Guide or the H06.nn Software Installation and Upgrade
Guide.
SWAN and SWAN 2 Concentrator File Conventions
Support for the SWAN 2 concentrator is provided as a separate file in the same
product version. The SWAN concentrator file convention is CnnnnP00. The SWAN 2
concentrator file convention is CnnnnQ00. For example, T7953G01 SWAN
FIRMWARE now contains two separate firmware files: C7953P00 (SWAN) and
C7953Q00 (SWAN 2).
Note. Throughout this manual when a distinction between a SWAN concentrator (T3880) and
a SWAN 2 concentrator (T3881) is not required, SWAN concentrator is used as a collective
term.
