Module Type IOM
Part Number 7660-411
Slot Number Mounts in chassis rear behind corresponding CPU
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.
ETHERNET – RJ48 modular connector.
