Description The CPU IOM provides physical access to the system
for Ethernet and also provides the remote shutdown
interface as explained below.
Controls REMOTE SHUT-DOWN – Spring terminal block for
installing cables for remote CPU shut-down. A remote
contact closure is used to short pins 1-2 or pins 3-4.
Jumpers control how these contact closures work.
Jumpers REMOTE SHUT-DOWN – Two user-installed
jumpers on the component side of the module control
how the remote contact closures work. As shipped, the
jumpers connect pins 1-2 to pins 3-4 so that shorting
either pair will reboot both CPUs. With the jumpers
removed, shorting pins 1-2 will reboot the other-slot
CPU; shorting pins 3-4 will reboot the same-slot CPU.
It is recommended that the jumpers be removed.
Connectors SERIAL – reserved for future use.
