CPU IOM Installation
3. Firmly press the Protection SAM IOM into the chassis until the connectors
completely seat.
4. Secure the retaining screws on the top and bottom of the module, being careful
not to over-tighten.
CPU IOM Installation
1. Before installing the CPU IOM, an adjustment may be needed to configure the
remote shutdown operation. There are two jumpers on each CPU IOM module
labeled JMP1 and JMP2. These jumpers control how the remote shutdown
contacts work. As installed at the factory, jumpers JMP1 and JMP2 connect
pins 1-2 to pins 3-4 so that shorting either pair will reboot both CPUs. With
both jumpers removed, shorting pins 1-2 will reboot the other-slot CPU;
shorting pins 3-4 will reboot the same-slot CPU. For a redundant unit with two
CPUs, it is recommended that both jumpers be removed so that the CPUs can
be rebooted individually without disrupting system operation.
2. Visually verify that each CPU IOM physically aligns with its respective CPU
installed above, slots Q and R respectfully.
3. Firmly press each CPU IOM into the chassis until the connectors completely
seat.
4. Secure the retaining screws on the top and bottom of each module, being
careful not to over-tighten
APM IOM Installation

power source, as well as fuse holders for two spares.
