Maintenance and Service Guide
Tip: Following is an example of how the baud rate is set while replacing a controller:
Example: A controller pair is operating with ACS V8.8-x with the top and bottom
at 4800 baud. The bottom controller is to be replaced. As such, you would
complete the following steps:
1. Issue the SET FAILOVER command on the top controller.
2. Use
FRUTIL to replace the bottom controller with a factory fresh controller and
a V8.8-
x program card.
3. As part of the installation, initialize the fresh bottom controller with a Port #5
button reset, which sets the controller speed to 9600 baud.
4. Later, while Dual-redundant mode is re-established by issuing a SET
MULTIBUS COPY=THIS or SET FAILOVER COPY=THIS on the top
controller, the fresh bottom controller reverts to the 4800 baud setting
supplied by the top controller as the remembered partner setting.
Note: A maintenance port cable (see Figure 16 on page 52) is provided for
connecting to a PC. This cable has a 9-pin connector molded onto one end, to which
three optional adapters can be attached for making a maintenance terminal
connection.
Use the following steps to establish a local connection for setting the initial array
controller configuration:
1. Turn off the PC or terminal, and connect the maintenance port cable to the
array controller, as shown in Figure 16 on page 52.
■ For a PC connection, plug one end of the maintenance port cable into the
communication port of the PC; plug the other end into the array controller
maintenance port.
■ For a terminal connection, see Figure 16 on page 52 for cabling
information. Adapter part numbers are provided in the “Subsystem
components—exploded views” section (on page 24) under the specific
subsystem type.
