The maximum cable length is six meters. You can connect one
device per SAS PHY unless you use an expander.
System throughput problems can occur if the SAS cables are
not the correct type. To minimize the potential for problems:
a. Use cables no longer than six meters (using shorter cables
is preferred)
b. Use cables that meet the SAS specification
c. Route the SAS cables carefully
Step 9. Turn on the Power to the System
Reinstall the computer cover and reconnect the AC power
cords; then, turn on the power to the computer.
Make sure that the power is turned on to the SAS devices and
the SATA II devices before or at the same time as the host
computer. If the power is turned on to the computer before it is
turned on to the devices, the computer might not recognize the
devices.
