9.3.2—Replacing a VME Module
For Simplex systems this procedure will shutdown the control
system.
If power has not been removed from the control system, power will
be active at the module and also at the cable connectors. It is
recommended that the cables not be removed until after the module
has been unseated. If cables are removed with power applied, care
must be used to avoid shorting cable connector pins.
HIGH VOLTAGE—If the high voltage FTM is being used with the 48/24
Discrete I/O module, and there is 125 Vdc on the FTM terminal
blocks, there will be 125 Vdc on the FTM sub D connectors and on
the cable when it is connected to the FTM. For this reason, all power
should be removed from the FTM terminal blocks before
disconnecting any cables.
VME Module Replacement Procedure:
1. Remove the cable saddle at the top of the chassis section. The saddle can
be lifted off by removing the two screws which hold it in place.
2. Unscrew the module’s captive-screw fasteners (one at the top of the module
and the other at the bottom), and unseat the module by simultaneously
pressing the top module handle up and the bottom module handle down.
3. Pull the module straight out along the card guide slots until it is
approximately 25 mm (1 inch) from the motherboard. Disconnect the I/O
cables from the module, and secure the ends to avoid damage or shorting of
pins. The I/O cables use a slide latch (to disengage, slide the latch towards
the top of the module).
4. Remove the module by pulling it straight out and putting it into a conductive
plastic bag.
5. Prior to installing a replacement module, verify that all connector pins are
parallel and straight. Install the replacement module by aligning the circuit
board edges inside the card guides and pushing the module straight in until
it is approximately 25 mm (1 inch) from the motherboard.
6. Connect the I/O cables to the module. The I/O cables use a slide latch (to
engage, slide the latch towards the bottom of the module). Verify that the I/O
cables are connected to the correct cable connector.
7. With even pressure exerted at the top and the bottom of the module, seat
the module into the motherboard.
8. Tighten the two captive-screw fasteners (one at the top of the module and
the other at the bottom).
9. If power was removed, reapply power.
10. Put the CPU module back in run mode.
11. Verify that the replacement MicroNet module is working correctly.
12. Reinstall the cable saddle.
