module bus. Additionally, each INIIT02 module in a redundant
interface must have its own I/O expander bus. The INNIS01
modules communicate to their respective INIIT02 modules
through these isolated I/O expander buses. To isolate a mod-
ule mounting unit:
1. Select the module mounting unit that will be dedicated to
the INIIR01 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 Controlway or module bus on that module
mounting unit.
NOTE: The I/O expander bus for each set of one INNIS01 module
and one INIIT02 module must be as short as possible. Bailey recom-
mends that adjacent MMU slots be connected for each set of inter-
face 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 INIIR01 Interface Modules
The INIIR01 interface modules are ready to install if:
•
Both INIIT02 modules have their dipswitches and jumpers
set (four INIIT02 modules on redundant interfaces).
•
Both INNIS01 modules have their dipswitches and jumpers
set (four INNIS01 modules on redundant interfaces).
•
The required number of NTCL01 termination units or
NICL01 termination modules and cables are installed.
•
The required number of NTMP01 termination units or
NIMP01 termination modules and cables are installed.
•
The module mounting unit has been checked for -30 VDC
and modified if necessary.
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.
