I/O Modules

The I/O module is a component that controls how the controller and the drives interact.
It connects with controllers.
A drive enclosure has one or two I/O modules.
When a drive enclosure has one I/O module, another module can be added during system operation. If one of
the I/O modules fails in a drive enclosure with two I/O modules, the failed I/O module can be replaced while
the system is running.

Power Supply Units

The power supply unit transforms input AC power from a power socket to DC power and supplies power to
each component. Each power supply unit contains fans.
A drive enclosure has two power supply units, which makes it possible for a failed unit to be replaced while
the system is running.
4.2.3

Drives

Up to twelve 3.5" drives can be installed.
Drives can be added during system operation. When an error occurs, replacement operations can be per-
formed while the system is running.
