 b. Disengage both controller retaining levers, and remove the controller
from the enclosure (see Figure 7 on page 17).

all device ports and asks if a replacement controller is available.
 b. Enter N(o) after FRUTIL asks you if a replacement controller is available,

the instructions in “Installing an HSG60 or HSG80 Controller in
Dual-Redundant Controller Configurations.”
Caution: If reverting to a single-controller configuration, fill the vacant
controller bay with a blank bezel to prevent the enclosure from developing an
over-temperature condition.
