PRO EX Installation and User’s Manual
4. Installation
• Turn of the computer and remove the power cord.
• Do not install the power cord for the PRO EX until after installation
of all add-on cards are completed.
• PRO EX has remote power control. There is no power on/off
switch on the PRO EX, power is controlled by the Uplink Host
Adapter installed in the host computer. When the host computer is
on, the PRO EX will come on, when the host is turned off, the PRO
EX will turn off.
The PRO EX is a PCI-e expander, which consists of an Uplink Host Adapter, a
Uplink Cable, and the expander enclosure. Additional user supplied PCI-e add-
on cards are installed in the PRO EX enclosure. The add-on cards can be Dulce
Systems’ SATA RAID Controllers, eSATA Adapters, FireWire / USB Adapters as
well as 3rd party RAID Controllers or any PCI-e compliant cards can fit into the
PRO EX enclosure.
4.1. Uplink Host Adapter Installation
An available PCI-e slot is required in the computer to install the PRO EX Uplink
Host Adapter. The slot must allow for an x8 physical card, however the speed of
the slot can be of x8 or slower. No drivers are required for the Uplink Host
Adapter and the Adapter is Mac and PC compatible.
The Uplink Host Adapter is rated for x8 speed which will produce the optimum
performance. But in some cases due to limitations of the computer, a slower
speed (x4 or slower) might be required to provide a balanced speed setting for
other PCI-e cards within the computer system.
For Mac Pro installations, slot 3 or 4 (top two) are recommended. Mac
Pros built on and after January 2008 have fixed speed of x4 in slots 3
and 4. Mac Pros before January 2008 might require setting of slot
speed using the Expansion Slot Utility.
