Chapter 8. Frequently Asked
Questions
Q: Does the SCON support SNA over ESCON?
A: No. The SCON product line is dedicated to supporting Non-SNA
communications over ESCON. If SNA communications is required, you can
use the 1174-25S instead. The 1174-25S is capable of supporting both Non-
SNA and SNA communications over ESCON.
Q: Does the SCON support Bus and Tag connections?
A: No. Only ESCON host connections are supported. You can use the 1174-25S to
support both Bus and Tag connections and ESCON connections on the same
platform. Up to 2 ESCON and 2 Bus and Tag interfaces may be supported at
the same time on the 1174-25S.
Q: Does the SCON-2XL support the IBM 3290 plasma display?
A: Yes. The SCON-2XL supports the IBM 3290 to allow the support and display
of up to 4 sessions at one time. In order for the 3290 to work, you must insure
that the files requested by the 3290 for download when it communicates with
the SCON-2XL are available either on the hard drive of the SCON-2XL or in
the floppy drive. 3290 DSL code is available from IBM or Visara if it is not
already loaded on the 2XL hard drive. Note, that DFT terminals such as the
3290 and many PC packages will not allow for connection to multiple LPARs.
They will only let you have multiple sessions on the same LPAR.
Q: Can a coax terminal communicate with multiple LPARs?
A: Yes. A coax (CUT) terminal can support up to 10 host sessions at one time.
These sessions can be spread across one or more LPARs.
Q: Can you attach StorageTek Silos to the SCON-2XL.
A: Yes. The LMU (Library Management Unit) used to manage the Silos will attach
to the 2XL using coax connections. You need to enable file transfer for the
ports that will be supporting the LMU, as well as enable the RPQ “Coax Poll
Rate” in the SCON-2XL configuration.
Q: Can StorageTek LMUs make use of the MLS (Multiple Logical Session) feature
of the SCON-2XL to communicate with multiple LPARs through a single coax
connection.
A: No, you must use a separate coax connection for each LPAR that you wish to
communicate with. The SCON-2XL can provide access up to 16 LPARs to an
LMU, through separate coax cables for each LPAR.
Q: Is there any way to remotely manage the SCON?
A: Yes. The SCON supports Telnet and a serial interface for dial-in. The biggest
concern for remote management is probably security. The SCON can be
configured to challenge either interface for a password to gain access. If remote
access via Telnet is to be used, it is recommended that a Virtual Private Network
(VPN) be used to help with security. Besides using a standard Telnet interface
for management, Visara offers a management platform, eManager, that can be
used to provide additional capabilities for remote problem determination and
microcode management.
