Hardware Installation Steps
4. Install the hard drives into the drive expansion bays. (Depending on your
computer model, mounting brackets/carriers or mounting sleds may be
required to install your hard drives. Refer to your computer’s user manual.)
5. Using only the supplied Ultra ATA cable, you may connect one or two
drives. If you are connecting two or more drives to two Ultra ATA cables,
skip to the next step; otherwise, connect the drives as follows:
• When connecting one drive, plug in the Ultra ATA cable’s master (black)
connector to it (Figure 4).
• When connecting two drives, connect the Ultra ATA cable’s master
(black) connector to the drive with jumpers set in the master setting;
connect the slave (gray) connector to the drive with jumpers configured
in the slave setting (Figure 4).
6. Using two Ultra ATA cables, you may connect two, three, or four drives;
connect them as follows:
• When connecting two drives, plug the Ultra ATA cables’ master (black)
connectors into the drives (Figure 5).
• When connecting three or four drives, connect the Ultra ATA cables’
master (black) connectors to the drives with jumpers set in the master
setting; connect the slave (gray) connectors to the drives with jumpers set
in the slave setting (Figure 5).
7. Locate the 4-pin power connector plugged into your computer’s exist-
ing hard drive. You should find at least one extra power connector near
the existing drive; if you have installed only one new drive, plug the extra
power connector into it. If you have installed more than one new drive,
or there are no additional power connectors, you must use power cable Y-
adapters (sold separately). Verify the connectors are plugged in securely.
8. Locate an available PCI slot inside your computer and remove its port
access cover, if present, from the rear of the computer.
9. Remove the Tempo Trio card from its packaging.
10. Install the Tempo Trio into the PCI slot; make sure the card is firmly
seated and secured.
11. Route the Ultra ATA cable(s) to the Tempo Trio card; avoid the processor’s
heat sink and make sure the cables will not get crushed or pinched by any
part of the case when the computer is reassembled.

Desktop users must remove the access panel on the main chassis to
route the Ultra ATA cables from the drives to the Tempo Trio. You may need tools
to perform this procedure. To remove the access panel, first unlock and tilt up the
internal assembly; remember to lower the assembly support stand. Next, firmly
twist the top edge of the panel forward toward the power supply, then lift the
panel out (Figure 6). Save the panel in case you ever need to use it again.
