IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User's, and Maintenance Guide
The storage subsystem has two interchangeable hot-swap and redundant
fan FRUs. Each fan FRU contains two fans. If one fan FRU fails, the
second fan FRU continues to operate. Both fan FRUs must be installed to
maintain proper cooling within your storage subsystem, even if one fan FRU
is not operational.
The DS4300 dual-controller storage subsystem (model 60U and 60X)
comes with two hot-swap power supplies. Both power supplies must be
installed to maintain proper cooling.
Note: The DS4300 single-controller storage subsystem (model 6LU and
6LX) comes with one power supply. You must keep the second
power supply bay cover on to maintain proper cooling.

Each RAID controller contains several connectors and LEDs. Each
controller has two host ports and one expansion port for connecting the
storage subsystem to hosts or expansion units. You first insert SFPs into
the ports and then connect the fibre channel cables.
Note: The DS4300 single-controller storage subsystem (model 6LU and
6LX) contains only one RAID controller and does not contain any
expansion ports.
The host ports are used to connect a fibre channel cable from the host
systems. You first insert an SFP into the port and then connect a fibre
