Chapter 2. Installation
7. Ensuring that the Power switch on the front of the Console Concentrator is off,
plug the Console Concentrator into an appropriate AC outlet.
8. Turn the Console Concentrator on (see Chapter 4, “Operation”). After a few seconds,
messages will appear on the LCD of the Operator Panel. These messages will change
as the unit proceeds through the various IML states until it has completed the boot
up procedure. When the boot has completed, the word ‘CONFIGURATION’ should
appear on the LCD. This initial boot process should take a few minutes (less than
10). If the boot process has not completed, or if you see a message that begins with
‘ERR’ or ‘XCP’, then a failure of the boot process has occurred. If a failure of the
boot process occurs, you will want to contact your Service Provider or the Visara
Intellicenter for assistance. Removal of the covers by unauthorized persons can
void your warranty.
9. Configure the Console Concentrator for use (see the SCON-20L/22L/25L/28L
Configuration Manual, SCON-20L/22L/25L/28L Installation Guide, and LINCS
Central Control manual).

the use of plastic seats and covers, and avoiding low humidity levels. The unit should be
located away from areas that generate electromagnetic interference (for example,
transformers, power distribution panels, and motors). The unit should not be installed
where the atmosphere contains corrosive elements that may damage the unit.
Cable runs should avoid areas that produce electromagnetic interference (for example,
near transformers, switching equipment, power distribution panels, and under carpets
where vacuum cleaning is done). Also, heavy equipment should not be moved or rolled
over the cable.
Connections
ESCON Channel Interface
An ESCON Controller (ESC), a PCI Feature Adaptor (PFA) board with a Luminex
ESCON board permanently connected/mounted in place, provides a single ESCON
Channel communications interface. The ESC provides a single channel attachment
interface for connecting the 20L/22L Console Concentrator to an ESCON director or to
a mainframe ESCON channel.
The fiber connection from the mainframe to the ESC shall be multimode 62.5/125 micron
cable for distances up to 3 kilometers with no directors, or 9 to 26 kilometers with 2
ESCON directors in series. Multimode 50/125 micron cable may also be used for
distances up to 2 kilometers with no directors, or 6 to 24 kilometers with 2 ESCON
directors in series.
