2 – QLA2340/2340L
Installation in the Computer
FC2354601-00 A 2-3
Perform the following steps to install the QLA2340/2340L HBA in your PC:
1. Check the motherboard and make any configuration changes necessary to
accommodate the QLA2340/2340L HBA.
The QLA2340/2340L HBA is self-configuring; however, some motherboards
require manual configuration. For example, some systems have a PCI
Device Configuration menu in the motherboard setup BIOS where you
must enable HBAs, bus master slots, and IRQ levels. If the motherboard
supports triggering, use level triggering for the QLA2340/2340L 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:
■ Some motherboards have two kinds of PCI bus slots: master
and slave. The QLA2340/2340L HBA must be in a PCI bus
master slot. (Some motherboards have PCI bus master slots
that are shared with onboard devices. QLA2340/2340L HBAs
do not work in shared slots.)
■ PCI connectors vary among system HBA manufacturers. The
QLA2340/2340L 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
QLA2340/2340L HBA into a PCI slot that does not conform to
the PCI specification, you may damage the QLA2340/2340L
HBA.
■ 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.
■ The QLA2340/2340L 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
QLA2340/2340L HBA.
6. Place the QLA2340/2340L HBA into the slot. Carefully press the HBA into
the slot until it seats firmly.
7. Secure the QLA2340/2340L HBA to the chassis. Follow the PC
manufacturer’s instructions.
