Chapter 1 – Introduction
Congratulations on your purchase! xMac mini Server
Thunderbolt 3 Edition (T3E) is a Thunderbolt 3 to PCIe card
expansion system and 1U rackmount enclosure for Mac
mini with Thunderbolt 3 ports. Through its two PCIe slots,
you may connect two expansion cards to your Mac mini to
expand its connectivity and processing capabilities.
xMac mini Server T3E has numerous thoughtful design
touches. The fans are user-replaceable. The front panel
USB-A port connects to the Mac mini, enabling you
to connect a keyboard, mouse, or thumb drive to the
computer without having to access its ports from the
back. Other Mac mini interface ports are extended to the
back of the chassis and mounted on the rear panel for
convenient interfacing of 10 Gigabit (or Gigabit) Ethernet,
USB-A, and HDMI cables. The xMac mini Server's power
switch turns the computer on and off, and the PCIe slots
are powered on/off with the Mac mini for maximum
energy savings. The front panel USB-A port lights up
when the computer is powered on. There's a central power
hub for the computer and power supply for the PCIe slots,
enabling you to power everything with one power cord. A
Thunderbolt 3 connector retainer clip and holes for cable
ties enable you to secure all cables, keeping them tidy
while avoiding accidental disconnects.
While xMac mini Server T3E requires no drivers, the
expansion cards you install do; Thunderbolt-compatible
drivers to enable them to work properly through the
Thunderbolt interface are required. More information
on which cards are compatible with xMac mini Server
is available at http://sonnettech.com/support/charts/

Chapter 5 – Tips and Known Issues
TIPS
Cooling xMac mini Server and Everything Inside It
With its optimized airflow design and temperaturecontrolled fans providing adequate cooling at all times,
xMac mini server may be installed anywhere in a rack.
Do not block any of the vents! Otherwise, the Mac mini,
installed cards, and xMac mini Server’s components may
overheat.
Connecting Additional Thunderbolt 3 Peripheral
Devices
The xMac mini Server T3E includes two Thunderbolt 3
ports; the first is reserved for connection to your computer,
while the second supports daisy-chaining of up to five
additional Thunderbolt peripheral devices.
Using Expansion Cards Without Drivers
Some Thunderbolt-compatible expansion cards, like
Sonnet’s Allegro™ Pro USB 3.1 PCIe and Solo10G™ PCIe
card, use drivers built into the OS, and are ready to use out
of the box. Cards listed as Thunderbolt-compatible, but
stating “no drivers required” fall into this category.
Replacing Cards or Adding Cards After Initial
Installation
If you decide to replace or add a card to xMac mini server
after the initial setup installation, shut down the system
and disconnect power to it before installing a card.
xMac mini Server T3E Provides Upstream Power
For connected peripheral devices requiring extra power,
the xMac mini Server T3E provides up to 15 watts of
power to bus-powered devices through its secondary
Thunderbolt 3 port.
How to Identify Thunderbolt 3 (40Gbps) Cables
Look for the Thunderbolt icon (
on the connector housings to identify these cables. Cables
with USB-C connectors that only have the Thunderbolt
icon without the number 3 support 20Gbps speeds, and
are not recommended for PCIe cards with high bandwidth
requirements. Cables marked with the USB icon (
NOT compatible for use connecting your computer to the
xMac mini Server T3E.
) AND the number 3
) are
KNOWN ISSUES
Not all PCIe Cards Will Perform at 100%
Thunderbolt 3’s PCIe bandwidth is limited to 40Gbps.
While many cards will operate at full performance, some
may not due to the fact they require more bandwidth
than Thunderbolt 3 is capable of delivering.
OS Updates May Break Compatibility
Specific device drivers that work under one operating system
version may not work under a later version. It is even possible
that an OS update may break compatibility. Before updating
to the latest drivers or OS version, we recommend that you
contact your PCIe cards’ manufacturers to verify that the
existing drivers work, and check online forums for reports
of issues with the latest OS update.
Some Devices’ Performance May be Affected by Where
They Are Connected in a Thunderbolt Chain
However small, Thunderbolt introduces latency to a
device chain. If you expand with additional Thunderbolt
expansion chassis, you may need to experiment with
which cards work better in chassis closer or farther to the
Mac mini in the chain.

C – Fan Switch Setting Information
The xMac mini Server includes a fan speed switch which enables you to
change when the main fans’ speed increases relative to the temperature
inside the enclosure. Regardless the switch setting, the fans’ starting
speed is the same. Note that this switch does not affect the power supply’s fan
operation.
Figure A3
• In High Speed Mode (factory setting), the fans’ speed begins to increase
when the temperature inside the enclosure exceeds 25˚ C (77˚ F), and
reaches full speed at 40˚ C (104˚ F). This setting is appropriate for all
compatible cards and is the default setting.
• In Low Speed Mode, the fans’ speed begins to increase when the
temperature inside the enclosure exceeds 35˚ C (95˚ F), and will speed up
somewhat as the temperature climbs toward 40˚ C (104˚ F). This mode
is appropriate for most PCIe cards except 10 Gigabit Ethernet controllers,
Fibre Channel controllers, SAS and SATA RAID controllers.
• A quiet fan kit (Sonnet part number XMFAN-Q-A) is available for
separate purchase for customers who want even quieter operation than
possible with the standard fans. This kit is suitable for most PCIe cards
except 10 Gigabit Ethernet controllers, Fibre Channel controllers, and SAS
