Chapter 7 – Tips, General Information, and Known Issues
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.
OS X Updates May Break Compatibility
Specific device drivers that work under one version of OS X
may not work under a later version. Before updating to the latest
OS, we recommend that you contact Sonnet to verify that the
existing drivers work. Note that other software updates for the
computer may also break compatibility.
TIPS, GENERAL INFORMATION
Keeping the Adapter Cool
With its optimized airflow design and automatic, temperature-
controlled fan providing cooling at all times, the Echo 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 Echo Adapter
You may connect and disconnect the Thunderbolt cable between
the Echo adapter and your computer while your computer is on.
Connecting Additional Thunderbolt Devices
You may connect up to six Thunderbolt devices total in a daisy
chain, including the Apple Thunderbolt Display.
There’s No Need to Unplug the Power Adapter
Because the Echo 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.
Power Indicator Operation
Because the Echo adapter powers on and off with the computer
to which it’s connected, its power indicator only lights when the
computer is on, and turns off when the computer is sleeping
or powered off. Note that the power adapter’s power indicator
remains lit as long as it is connected to a live power outlet.
