Sonnet Technologies Echo Express SE 10GbE User's Guide [Enghlish] - Manual (Page 11)

Chapter 6 – 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
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 the 10GbE card inside. Do not block any
of the vents while the adapter is operating! Otherwise, the card and
other components 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 the Echo adapter plus up to five additional
Thunderbolt devices, (including the Apple Thunderbolt Display)
in a daisy chain connected to the computer
No Power Switch, and 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 on
the adapter, 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
