Replacing the processor
The processor PCB is mounted inside the enclosure on four standoffs.
Removing the processor assembly
1. Label and disconnect the removable terminal blocks.
2. Disconnect the tamper switch connector from the processor.
3. If required, remove the network interface card and its ground wire.
4. Remove and retain the mounting hardware from the processor CCA (2 standoffs, 2 machine
screws + washers).
5. Lift the processor CCA out of the enclosure. Place the CCA into an anti-static bag.
Replacing the processor assembly
1. Fit the replacement processor inside the enclosure so the 4 mounting holes are lined up with
the standoffs.
2. Use the retained mounting hardware to secure the CCA to the enclosure.
3. If required, replace the network interface card and its ground wire.
4. Reconnect the tamper switch connector.
5. Reinstall the removable terminal blocks.
6. Apply power to the processor, connect the UCM and download the replaced processor’s
configuration file to the replacement processor.
7. Thoroughly test the replacement processor.
CAUTION The processor and the NIC include static sensitive components.
Follow proper ESD handling procedures when working on the PCB.
Place both assemblies into anti-static bags once they are removed
from the enclosure.
