SCON-20L/22L/25L/28L/3074 Planning and Installation Guide
Q: Does the SCON support VPNs?
A: No, not directly. You can use external products to provide the Virtual Private
Network security.
Q: Does the SCON support Secure Socket Layer communication over the network?
A: No, not directly. Visara does have a companion product, the SSL1000 that
provides SSL security as well as provides session failover support for a pair of
SCON platforms.
Q: Does the SCON support international languages?
A: Yes. The host communications can be any one of a great many languages
supported by the LINCS software. The configuration process however, Central
Control Mode and any error messages that are generated by the SCON itself,
will be in English.
Q: Does the SCON have any provisions for redundancy?
A: The SCON-25L/28L/3074 supports 2 ESCON interfaces, allowing you to
provide multiple paths to your LPARs.
Q: What is the difference between the TN3270E support and Telnet support?
A: The Telnet interface make use of Asynchronous emulations such as VT220,
IBM3151, Wyse60, etc., to provide CUT communication to the SCON-2XL. As
a CUT emulation, the SCON-2XL can provide multiple LPAR access through a
single connection, as well as access to 2XL management panels if needed, however
the keyboard mapping is not usually as clean as with TN3270E. The screen
presentation provided by Telnet is limited in the way some attributes can be
portrayed since the set of attributes, and the way they are managed are different
from a 3270 native emulation. The TN3270E provides a more natural looking
console emulation, with typically better keyboard mapping. TN3270E clients
must establish multiple virtual connections across the network to support multiple
console sessions. TN3270E clients do not have access to the 2XL management
panels, and are therefore better suited for console or application users.
Q: Does the SCON support all TN3270E clients.
A: Yes, for the most part. All of the more popular emulators, as well as many
more obscure ones will work. There is nothing about the TN3270E interface
that should preclude the operation of a specific emulator. You may however
wish to contact a Visara representative for a list of PC emulations that are known
to work as consoles.
Q: Does the SCON support a FICON interface?
A: Not directly. You can connect the SCON to an ESCON Director that is in turn
fed by a FICON link.
Q: If there is a power failure, will the SCON automatically recover?
A: Yes. The SCON should power back up and automatically go online. The process
should be complete within 5 minutes. It will probably be necessary to vary the
console sessions active again, since a failed console connection will normally
roll to another console or to the support element.
