Chapter 3 – PCIe Card Installation Steps

12.

 Turn the Echo Express SEL right-side-up.

13.

 Connect the included Thunderbolt cable between either Thunderbolt 

port on the Echo chassis and a Thunderbolt port on your computer, 
or other Thunderbolt device in the chain connected to the  
computer 

(Figure 8)

. Secure the retainer clip to the chassis  

if you attached it. If you are daisy chaining additional  
Thunderbolt devices, connect another Thunderbolt cable  
between the downstream device and the open  
Thunderbolt port on the Echo chassis.

14.

 Connect the included power cord between a wall outlet  

or power strip and the power adapter; verify the  
connector is plugged in securely. Note that the power  
adapter’s power indicator will light at this time.

15.

 Connect the power adapter cable to the Echo Express SEL’s 12V power 

socket. Note that the power indicator on the Echo Express SEL chassis 
will not light until the computer, and any other Thunderbolt device 
connected between it and the Echo chassis, is powered on.

 Support  Note:

 Sonnet’s ThunderLok™ Thunderbolt connector 

retainer clip secures the included Thunderbolt cable to the Echo 

chassis to prevent accidental disconnects. Although it is compatible with 
some other copper Thunderbolt cables like Apple’s, it is not compatible with 
optical Thunderbolt cables. 

To attach the clip to the cable, remove them from their packaging. Turn one 
of the cable’s connectors so the Thunderbolt icon is facing down, and then 
insert the connector into the connector clip as shown 

(Figure 7)

. Note that 

the connector will pass all the way through the clip; when you connect the 
cable to the chassis, the clip will secure the cable.

 Support  Note:

 To ensure the best performance possible when 

connecting multiple Thunderbolt devices in a daisy chain, be sure to 

connect 20Gbps Thunderbolt 2 devices such as this Echo chassis closest to 
the computer, with 10Gbps Thunderbolt devices at the end.
