Planning for the Visara 500Lx
The Visara 500Lx product is designed to support console sessions
in a rather unique way. You can use it to display multiple console
sessions on the screen (up to 4 full screen console sessions)
through its TN3270E feature when using a monitor capable of
supporting 1280 x 1024 resolution. Unlike other TN3270E clients
however, you can optionally attach the 500Lx directly through a
coax connection (fewer security issues). The 500Lx also supports
an Ethernet connection.
Planning for Hot Console Sessions
One of the unique features available for the CCA-3074 allows
Console sessions to remain powered on with the host LPAR, even
when the client associated with the session is not currently
connected. This is referred to as a Hot Console Session.
Applications for the Hot Console Session include:
• Provide console connections for a lights out site.
• Provide a means for multiple operators, located in multiple
locations to have access to the same console session at
different times.
• Provide a tool for disaster recovery from a remote location.
Hot console sessions do not roll over to an alternate console
unless the CCA-3074 is powered down, varied offline, or is no
longer functional.
Use of Channel Extenders
There is nothing unique about the CCA-3074 that should cause
problems using channel extenders. However, Visara has
conducted no special testing with specific channel extenders to
verify their correct operation. It is the customer’s responsibility to
determine compatibility with another vendor’s channel extender,
when used with the CCA-3074. Because the CCA-3074 supports
clients remotely through TN3270 sessions, it might be better (and
less expensive) to locate the CCA-3074 at the data center site and
connect remotely from a TN3270 client.
