Working with hot-swap RAID controllers (dual-controller models only)

Each RAID controller fits into the back of the storage subsystem and has the
following components:
v Battery
v Cache memory
v Two host ports and one expansion port
v One Ethernet port
v One serial port
Exception: The DS4300 single-controller storage subsystem (Model 6LU/6LX) has
only one RAID controller. Therefore, you cannot hot swap the RAID controller.
Each RAID controller has a unique hardware Ethernet address, which is printed on
a label on the front. There is also a label giving the cache battery manufacturing
and installation dates on the top of the controller unit. Figure 97 on page 135 shows
the location of these items.
