Installation Preparation
Sonnet strongly recommends that you read the section in your
computer’s user manual that addresses PCIe card installation, prior to
installing the Allegro card into your system.
Support Notes: When handling computer products, you
must take care to prevent components from being damaged
by static electricity. Before opening your computer or removing
parts from their packages, always ground yourself first by touching
a metal part of the computer, such as a port access cover, and work
in an area free of static electricity; avoid carpeted areas. Handle
all electronic components by their edges, and avoid touching
connector traces and component pins.
Card Installation Steps
1. Shut down your computer or Thunderbolt-to-PCIe card
expansion chassis, and then open it to access the expansion
card area (PCIe slots); refer to the user’s manual for specific
information.
2. Locate an available PCIe slot and remove its access cover.
3. Remove the Sonnet card from its packaging, and then install it
into the PCI Express slot; make sure the card is firmly seated
and secured.
4. Close the computer or Thunderbolt-to-PCIe card expansion
chassis.

USB Port Usage Information
The Allegro Pro USB 3.1 PCIe
card features two USB 3.1 Gen 2
controllers, with each controller
offering 10Gbps bandwidth shared
across two ports. One controller
supports the top two ports, and
the other controller supporting the
bottom two ports.
For the fastest drive-to-drive file
transfers when using USB 3.1 Gen 2
drives, Sonnet recommends that you
connect the source drive to one of the
top two ports, and the destination
drive to one of the bottom two ports.
Known Limitations and Advice
USB peripherals have some limitations you should be aware of, and
we have listed some additional advice here. Refer to the peripheral
manufacturers’ Web sites for more information.
• USB 3.1 Gen 2 devices require USB 3.1 Gen 2 cables to support 10
Gb/s transfer speeds Use of USB 3.0 cables between USB 3.1 Gen 2
devices and Allegro Pro USB 3.1 PCIe card is supported, but data
transfers are limited to USB 3.0 speeds (5 Gb/s).
• The use of USB-A to USB-C cables is supported, but data transfer
speeds are limited by the cable type (USB 3.1 Gen 2, USB 3.0, or
USB 2.0), as well as the speeds supported by the device.
• Many peripherals require additional drivers and application
software to operate or have full functionality. Software should
be included with the device, or available to download from the
manufacturer’s Web site. Check the peripheral’s user’s manual for
information about necessary software.
• While your computer is on, always “eject”, “stop”, “unplug”, or “put
away” any drive (hard drive, SSD, etc.) before disconnecting it from
its cable or the Sonnet card.
• While your computer is on, always “eject” any memory card from
the operating system before removing it from an attached card
reader, or disconnecting the reader (with the card inserted in it)
from its cable or the Sonnet card.
Known Limitations and Advice (continued)
• Although many peripherals may draw power directly from the
Sonnet card, other devices require an external power source.
Remember to use external power supplies when necessary.
• 1-meter or longer Thunderbolt 3 (40Gbps) cables DO NOT support
USB 3.0 & 3.1 by design, only Thunderbolt 3 & USB 2.0.
• The Allegro Pro USB 3.1 PCIe card is not compatible with
Thunderbolt 1 PCIe card expansion systems.
