3 – QLA2340/2340L

Installation in the Computer

FC2354601-00 E 3-3

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:

n 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.)

n 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.

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 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.

8. Connect the appropriate cable from the devices to the corresponding connector.
