 Support  Note:

 If you do not see “Echo Express SEL” 

listed, disconnect and reconnect the Thunderbolt 

cable between the computer and Echo Express SEL. Note 
that it is not necessary to shut down the computer before 
disconnecting and reconnecting the cable, so long as the 
installed card is Thunderbolt-compatible.

 Support  Note:

 While the Echo Express SEL 

expansion chassis requires no drivers, the installed card 

requires Thunderbolt-compatible drivers to enable its use.
