CPU IOM Connections

Remote Shutdown Connections

The CPU Remote Shutdown feature allows a connection to be made across one of the contact pairs to remotely close the contacts, which forces a reset of the CPU in the event that the CPU cannot be reset through software.

The behavior of these terminals are set by jumpers on the card (see “CPU IOM Installation” on page 5-12).

To use this feature, connect a cable to terminals 1-2 and/or 3-4 on the CPU IOM. (See example at right.) The spring terminal block accepts 26 to 18 AWG wire.

Serial Port Connections

This is a standard DB9 RS-232 DTE serial management port that can be connected to a serial terminal or PC running a terminal emulation program. Access to this port is determined by the security settings.

Ethernet Connections

This is a standard ethernet DTE management port that can be connected to an IP network. Access to this port is determined by the security settings.
