6. Install the replacement module by aligning the circuit board edge in the card
guides and pushing the module into its slot. To reduce the number of system
alarms, take care not to allow the module to become in contact with the
motherboard connector.
7. Re-connect both module I/O cables. The I/O cables use a slide latch (to
secure cable, slide the latch down). To eliminate the possibility of causing a
system trip when replacing a module always connect the I/O cables before
seating the module to the motherboard. (A system trip is possible if a number
of the cable connector pins are shorted to chassis ground.)
8. With even pressure exerted at the top and bottom of the module’s front
panel, push the module into place until the module connector is firmly within
the motherboard’s module receptacle. Once properly installed the module
Fault LED will be illuminated until the module is re-initialized by the control.
Upon installing the module, the control performs module diagnostic tests for
a few seconds, and if all test are passed, re-initializes the module (turning off
the module Fault LED).
9. Tighten the two screws that secure the module in place (one at the top and
one at the bottom).
NOTE
If the module’s Fault LED does not turn off after the module has been
installed for at least one minute, it may be necessary to re-seat the module
more firmly. To re-seat a module follow step #3 of the above procedure to
release the module from the motherboard, then re- install the module by
following procedure steps #8 and #9.
Serial Input/Output (SIO) Module
(Optional)
Two Serial Input/Output (SIO) modules are installed within the control chassis.
The SIO modules are installed in slot 5 of kernels A and B. Ports 1 and 2 are RS-
232 communications based ports only. Ports 3 and 4 can be configured for RS-
232, RS-422, or RS-485 communications. System diagnostics continuously
monitor each SIO module for proper operation.
SIO Module LED descriptions:
RUN LED
—The green LED turns on to indicate that the SIO module is
functioning and there are no faults present.
FAULT LED
—The red LED turns on to indicate a module fault has occurred and
is annunciated.
WARNING—HOT SWAPPING
Hot Swapping the SIO module can cause a dip in the 5 Vdc supply.
Depending on the severity of the dip, other modules or the CPU can be
forced into a reset state.
With this control, the removal of any single kernel will not cause the control
to shut down. However, if other faults are present within other kernels, those
faults, combined with any faults caused by shutting down the kernel power
supply, may cause a system shutdown.
