CCA-3074 Planning
707159-002 2-7
Coax Requirement Planning
The CCA-3074 does not support direct coax attachment. Coax
attachment can be provided using an external CSS32 Coax
Subsystem. These appliances can be directly attached to the
CCA-3074 using a crossover Ethernet cable, or may be positioned
elsewhere on your IP network, even at a remote location. Each
CSS32 Coax Subsystem can support up to 32 coax ports. One
CCA-3074 can communicate with multiple CSS32 appliances and
one CSS32 can communicate with multiple CCA-3074 platforms.
It is also possible to obtain a CSS32 that can support up to 128
coax devices. If you need to support more than 32 coax devices
contact a Visara representative to determine your options.
StorageTek LMUs Planning
StorageTek LMUs have a requirement to use a single coax
connection for each LPAR that you wish to connect the LMU to.
Be sure to allow for that in your calculation for the number of
coax connections needed. The CCA-3074 does not support coax
directly, but makes use of the external CSS32 to provide the coax
connectivity.
FICON Usage
The CCA-3074 supports a single FICON card. The card comes in
3 interface variations (single interface, dual interface, and quad
interface). The interfaces on each card also have the option of
using Long Wave or Short Wave transceivers and must be
ordered to work in your environment. FICON support can be
ordered as an upgrade to ESCON existing units and allows for the
coexistence of ESCON and FICON connectivity.
IBM 3290 Plasma Display Planning
The 3290 plasma display can support up to 4 sessions through a
single coax connection, but it is limited to communication to only
one LPAR. Coax connectivity is handled through an external
CSS32 Coax Subsystem available from Visara. An alternative to
the use of the 3290 would be to use the Visara 500LX thin client
product. The 500LX can support up to 10 sessions (in color),
including simultaneous full screen display of 4 sessions to
different LPARs.
