HDD-8263/8264 Installation Guide
Cabling
Connect the cabled PCI Express x4 cable to both NI 8262 and the
HDD-826
x
chassis. The cables have no polarity, so you can connect either
end to either the card or chassis.
Caution
Do
not
remove the cable after the system is powered on. Doing so can hang
or cause errors in applications communicating with devices. If a cable becomes unplugged,
plug it back into the system. (You may need to restart your computer.)
Note
For more information about cables, refer to the
Cable Options
section.
Powering Up the HDD-826
x
for PXI Express System
Follow these steps to power up the HDD-826
x
for PXI Express system:
1.
Turn on the HDD-826
x
chassis. The power switch is on the power
supply on the back of the chassis. The system should not power on
when this switch is turned on. Turning this switch to the ON position
enables the chassis to be powered on by the host controller when the
host is powered on.
2.
Power-on the host. The HDD-826
x
chassis should now turn on.
Driver Installation
For driver installation information, consult the driver installation chapter of
the included RAID controller user manual or guide.
Powering Down the HDD-826
x
for PXI Express
System
Because operating systems and drivers commonly make the assumption
that PCI devices are present in the system from power-up to power-down,
it is important not to power off the HDD-826
x
chassis independently.
Powering off the HDD-826
x
chassis while the host is still on can cause
data loss, crashes, or hangs. When you shut down the host controller,
the HDD-826
x
is sent a signal over the cabled PCI Express link to shut
down also.
Reconfiguring the RAID Arrays of the HDD-826
x
for
PXI Express Systems
The HDD-826
x
systems are preconfigured in RAID0 for performance
reasons. National Instruments does not recommend reconfiguring the
HDD-8264, as it validated to support only RAID0. There are two methods
of reconfiguring the RAID arrays.
