Chapter 3 – PCIe Card Installation Steps

12. Turn the Echo Express SE I T3E right-side-up.

13. Connect the included Thunderbolt cable (or a comparable

Thunderbolt 3 [40Gbps] cable) between a Thunderbolt 3 port on the

Echo chassis and a Thunderbolt 3 port on your computer, or other

Thunderbolt device in the chain connected to the computer

(Figure 8). Note that cables or ports marked with the USB icon

(

) are NOT compatible. 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 chassis 12V power socket.

Note that the power indicator on the Echo Express SE I T3E 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™ 3 Thunderbolt connector

retainer clip secures the included Thunderbolt 3 (40Gbps) cable to the

Echo chassis to prevent accidental disconnects. The included clip is compatible

with Sonnet 0.5- and 0.7-meter Thunderbolt 3 (40Gbps) cables, but it is not

compatible with Sonnet 1- or 2-meter Thunderbolt 3 (40Gbps) cables.

To attach the clip to the cable, remove both items from their packaging, and

then insert the connector through 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 connector.
