Chapter 7 – Tips, General Information, and Known Issues
TIPS, GENERAL INFORMATION
Keeping the Twin 10G SFP+Adapter Cool
With its optimized airflow design and automatic, temperaturecontrolled fan providing cooling at all times, the Twin 10G SFP+
adapter provides adequate cooling for the components inside. Do not block any of the vents while the adapter is operating! Otherwise,
the adapter may overheat.
Hot-Plugging the Twin 10G SFP+ Adapter
You may connect and disconnect the Thunderbolt cable between
the Twin 10G SFP+ adapter and your computer while your
computer is on.
Connecting Additional Thunderbolt Peripheral Devices
You may connect up to six Thunderbolt peripheral devices total
in a daisy chain, including a Thunderbolt Display, to a single
host computer. You may not connect two Thunderbolt computers to a Thunderbolt daisy chain of devices.
There’s No Need to Unplug the Power Adapter
Because the Twin 10G SFP+ adapter automatically powers on and
off with the computer to which it’s connected, there’s no power
switch, nor is there any need to disconnect the power cable under
normal use. When your computer is sleeping, the Twin 10G SFP+
enters a low-power state; this allows it to wake with your computer.
KNOWN ISSUES
Some Devices’ Performance May be Affected by Where They
Are Connected in a Thunderbolt Chain
However small, the Thunderbolt interface introduces latency to
a device chain. If you add additional Thunderbolt devices to the
chain, you may need to experiment with which device works
better closer or farther to the computer in the chain.
Operating System (OS) Updates May Break Compatibility
Specific device drivers that work under one OS version may
not work under a later version. Before updating to the latest
OS, we recommend that you contact Sonnet to verify that the
existing Twin 10G SFP+ drivers work. Note that other software
updates for the computer may also break compatibility.
Creating Intel ANS teams and VLANs on Windows 10 is
currently not supported
As a result, when created, teams and VLANs do not pass traffic.
We expect that ANS will be supported on Windows 10 client in a
future release.
Indicator Operation
Because the Twin 10G SFP+ adapter powers on and off with the
computer to which it’s connected, its external indicators light
only when the computer is on, and turn off when the computer
is sleeping or powered off. Note that the power adapter’s power
indicator will remain lit as long as it is connected to a live power
outlet.
