I/O Modules

The I/O module is a component that controls how the controller and the drives interact.
The I/O module is connected to the controller or an I/O module on another drive enclosure.
A drive enclosure has two I/O modules, which makes it possible for a failed I/O module to be replaced while the
system is running.

Drive Interface Ports
This port is for connecting controller enclosures or drive enclosures.
The drive interface port has an IN port and an OUT port.
This section provides the specifications for drive interface ports when 2.5" type drive enclosures and 3.5" type
drive enclosures are used.

Fan Expander Module (FEM)

An FEM is a cooling fan module. Two FEMs are installed in a high-density drive enclosure.
If one of the FEMs fails, the failed FEM 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 2.5" type drive enclosure and a 3.5" type drive enclosure have two power supply units, which makes it possible
for a failed unit to be replaced while the system is running.
A high-density drive enclosure has four power supply units and up to two failed units can be replaced while the
system is running.
