16. Disconnect the PC or terminal from the controller maintenance port.

Replacing HSG60 and HSG80 Controllers in Dual-Redundant Controller
Configurations
Follow the instructions in this subsection to remove or replace an HSG60 or
HSG80 controller in a dual-redundant controller configuration.
Caution: With ACS V8.7, V8.7-1, and V8.7-2, FRUTIL allows you to install
both the controller and cache module in the same process. HP does not
recommend this. Replacing both the controller and cache module at the same
time can result in loss of controller configuration information and will render
the controller unusable.
Note: With ACS V8.7-3, FRUTIL prohibits you from installing both the controller and
cache module in one process.
Caution: Electrostatic discharge (ESD) can easily damage the controller. Wear
a snug-fitting, grounded ESD wrist strap when completing controller removal
and installation procedures.
To differentiate on which controller activity is being completed, symbols are
displayed in the margin of text for your convenience. Table 2 describes those
