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 QLA22xx board must be in a PCI bus master slot. (Some
motherboards have PCI bus master slots that are shared with
onboard devices. QLA22xx boards do not work in shared slots.)
❑ PCI connectors vary among system board manufacturers. The
QLA22xx board is a 64-bit PCI device that can function in a 32-bit
PCI slot that conforms to the PCI specification (the rear edge of the
PCI slot is notched). If you try to install the QLA22xx board into a PCI
slot that does not conform to the PCI specification, you may damage
the QLA22xx board.
❑ The 66-MHz QLA22xx boards (indicated by /66 in their name) are
backward compatible; consequently, they can be used in a 33-MHz
slot.
5. Unscrew and remove the slot cover. Retain the screw; you will use it when
you install the QLA22xx board.
6. Place the QLA22xx board into the slot. Carefully press the board into the
slot until it seats firmly.
7. Secure the QLA22xx board to the chassis with the slot cover screw.
8. Connect the appropriate cable from the devices to the corresponding
connector:
❑ J1 (QLA2200/2200F/2202F/2200L)
❑ J1 and J2 (QLA2202F/2212F)
❑ J3 and J4 (QLA2212F). These are three-position point-to-point
adapters connected to J1. J3 is the transmit connector; J4 is the
receive connector.
❑ J1 through J4 (QLA2204F)
❑ J6 (QLA2200G)
9. Carefully reinstall the computer cover. Insert and tighten the computer cover
screws.
