2. Connect the fiber-optic cable to the installed SFP, as shown in Figure 35, using
the instructions as describe in "Connecting an LC-LC cable to an SFP module"
on page 37.

3. Check the LEDs on the RAID controller. When the RAID controller is operating
properly, the amber Fault LED is off. For information about the status of the
RAID controller LEDs, see Table 14 on page 99.
4. To remove the fiber-optic cables, refer to the instructions described in
"Removing an LC-LC fibre-channel cable" on page 39.
DS4300 Fibre Channel connections consist of two host fibre channel loops and up
to one drive fibre channel loop, depending on the storage subsystem model. These
fibre channel connections are made through three SFP ports, which are labeled
"Host 1," "Host 2," and "Expansion."
Exception: The DS4300 single-controller storage subsystem (Model 6LU/6LX) does
not support drive loops or storage expansion enclosures.
The host fibre channel loop provides the fibre path for host attachment. It can
consist of fibre channel cables, SFPs, host bus adapters, fibre channel switches,
