a diagram of a redundant interface with isolated Controlway/
module bus and two isolated I/O expander buses in a redun-
dant interface. To isolate a module mounting unit:
1. Select the module mounting unit that will be dedicated to
the INIIL02 interface.
2. Disconnect the Controlway/module bus cable from the
module mounting unit to be isolated for the interface.
Figure
shows an example of how the Controlway is discon-
nected to isolate the Controlway or module bus on that module
mounting unit.
NOTE: The I/O expander bus for each set of two INNIS01 modules
and one INIIT03 module must be as short as possible. Bailey recom-
mends that three adjacent MMU slots be connected for each set of
interface modules. Failure to keep the I/O expander bus short
results in unreliable operation.
3. There is no set procedure for isolating the I/O expander
bus because system architectures differ so widely from system
to system. The example in Figure
shows one way to isolate
the I/O expander bus. Using the methods (i.e., by removing a
dipshunt or a ribbon cable) shown in Figure
, isolate an I/O
expander bus for each interface.
INSTALLING THE INTERFACE MODULES
The INIIL02 interface modules are ready to install if:
•
The INIIT03 module has its dipswitches and jumpers set
(two INIIT03 modules for redundant interfaces).
•
Both INNIS01 modules have their dipswitches and jumpers
set (four NIS modules for redundant interfaces).
•
The required number of NTCL01 termination units or
NICL01 termination modules and their cables are installed.
•
The module mounting unit has been checked for -30 VDC
and modified if necessary.
•
An isolated module mounting unit has been prepared for
the INIIL02 interface.
WARNING
Disconnect power before installing dipshunts on the module
mounting unit backplane. Failure to do so will result in contact
with cabinet areas that could cause severe or fatal shock.
AVERTISSEMENT
Interrompez l'alimentation avant d'installer des dipshunts sur
le fond de panier du châssis de montage des modules. Sinon,
tout contact avec cette zone entraîne des risques d'électrocu-
tion sérieuse ou fatale.
