Jumpers

The jumpers on the QLA2310FL/2312F/2312FL boards set the default state of the

laser and are set at the factory with a jumper plug on pins 1–2 of the following

jumpers.

■ QLA2310FL (jumper J2)

■ QLA2312F (jumpers J1 and J4)

■ QLA2312FL (jumpers J3 and J4)

CAUTION!

Changing the jumper settings can result in the board being inoperable.

Power Distribution

The QLA2300 and QLA2310 boards supply +5 volts to pin 7 of the HSSDC copper

interface to support an external media interface adapter (MIA), if required. (An MIA

converts electrical bus signals to optical bus signals.)

Installation in the Computer

Perform the following steps to install the QLA23xx board in your PC:

1. Check the motherboard and make any configuration changes necessary to

accommodate the QLA23xx board.

The QLA23xx board 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 host adapter boards, bus master slots, and IRQ levels. If the

motherboard supports triggering, use level triggering for the QLA23xx

board. 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 QLA23xx board must be in a PCI bus master

slot. (Some motherboards have PCI bus master slots that are

shared with onboard devices. QLA23xx boards do not work in

shared slots.)
