Installing the Host Adapter

Inserting the Host Adapter in a PCI Slot

WARNING: 

Turn 

OFF

 and disconnect the 

power to your computer and attached 
devices before you remove the computer 
cover. 

1

Remove the cover from the computer case.

2

Locate an unused PCI expansion slot that sup-
ports bus mastering. Make sure this slot is not 
obstructed by other system hardware.

PCI bus slots are usually white or ivory and are 
shorter than ISA or EISA slots. Usually there are 
three PCI slots. One of these may be a shared slot. 
That is, it may have an ISA or EISA connector and 
a PCI connector, but only one kind of board can 
be inserted in the slot at any one time.

3

Remove the corresponding expansion slot cover 
from the computer chassis and save the screw.

4

Hold the host adapter directly over the bus mas-
ter PCI slot and insert the end of the board in the 
card guide. Carefully press the bus connector on 
the bottom of the host adapter down into the slot.

5

Attach the host adapter bracket to the computer 
chassis with the screw from the expansion slot 
cover that you removed.

Note: 

Do not replace the computer cover or 

reconnect the power yet!
