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.
