Q
enable HBAs, bus master slots, and IRQ levels. If the motherboard supports
triggering, use level triggering for the QLA2350/2352 HBA. See the
documentation supplied with your computer, or contact your computer dealer
to determine if your motherboard requires configuration.
2. Power down the peripherals, then the computer.
3. Remove the computer cover and save the screws.
4. Choose any PCI bus slot that supports bus mastering. Most motherboards
automatically assign an IRQ level and interrupt line; if your motherboard does
not, you must assign the IRQ level and use interrupt line A for this slot.
NOTE:
n Some motherboards have two kinds of PCI bus slots: master and
slave. The QLA2350/2352 HBA must be in a PCI bus master slot.
(Some motherboards have PCI bus master slots that are shared
with onboard devices. QLA2350/2352 HBAs do not work in shared
slots.)
n PCI connectors vary among system HBA manufacturers. The
QLA2350/2352 HBA is a 64-bit PCI device that can function in a
32-bit PCI slot; the slot conforms to the PCI specification (the rear
edge of the PCI slot is notched). If you try to install the
QLA2350/2352 HBA into a PCI slot that does not conform to the
PCI specification, you may damage the QLA2350/2352 HBA.
n PCI and PCI-X slots look the same. If the PC contains both PCI and
PCI-X slots, refer to the PC manufacturer’s instructions to
determine the slot type.
n The QLA2350/2352 HBAs are designed and tested to operate at
PCI bus speeds of up to 133 MHz.
5. Remove the slot cover for the slot in which you will install the QLA2350/2352
HBA.
6. Place the QLA2350/2352 HBA into the slot. Carefully press the HBA into the
slot until it seats firmly.
7. Secure the QLA2350/2352 HBA to the chassis. Follow the PC manufacturer’s
instructions.
8. Connect the appropriate cable from the devices to the corresponding
connector.
9. Carefully reinstall the computer cover. Insert and tighten the computer cover
screws.
