Maintenance and Service Guide
Establishing a local connection to the controller
Communication with an array controller is established locally or remotely. Use a
local connection to configure the array controller for the first time. Use a remote
connection to the host system for all subsequent configuration tasks. Refer to the
controller installation and configuration guide that shipped with the platform kit
for details.
Use the maintenance port, located on the front of the array controller, to connect a
PC or terminal to the array controller for troubleshooting or configuration
procedures. This port accepts a standard RS-232 jack from any EIA-423
compatible terminal or a PC with a terminal-emulation program. The maintenance
port supports serial communications with a default value of 9600 baud (using 8
data bits, 1 stop bit, and no parity bit).
Note: The serial maintenance port speed and character format characteristics can be
set with the SET THIS TERMINAL or SET OTHER TERMINAL CLI
command. In
dual-redundant controller configurations, these characteristics are set independently
for each controller.
A controller remembers its current serial port settings across power cycles, restarts,
and when it becomes dysfunctional. If the controller is configured as dual-redundant, it
also retains the settings of the partner controller, and remembers the other controller
when the SET NOFAILOVER command is entered.
After one of the following commands is issued (while there are any remembered serial
port settings), serial port settings are copied to the (possibly new) partner controller as
determined by the copy direction, and copied settings replace the previous settings of
that partner.
■ SET FAILOVER COPY=THIS
■ SET MULTIBUS COPY=THIS
■ SET FAILOVER COPY=OTHER
■ SET MULTIBUS COPY=OTHER
These settings are used when the controller is started with a program card containing
ACS firmware. However, any current settings can be overridden after the Port #5 reset
action is performed on a replacement controller with installed firmware. ACS V8.7,
V8.7-1, or V8.7-2 forces the controller speed to 19200 baud; and V8.7-3 through
V8.8-
x forces it to 9600 baud (8 bit data, no parity, one stop in both cases).
