Sonnet Technologies Echo Express III-R - Manual (Page 6)

Chapter 2 – Echo Express III-R Description
1 – Power Indicator LED
This lights when: the Echo Express III-R is powered, the Thunderbolt cable between the chassis and your computer is
plugged in securely, and the computer powered on.
2 – Temperature-Controlled Fans
These provide cooling for the installed PCIe cards and
the chassis’ supporting Thunderbolt circuitry. They
operate at a whisper when the cards are running cool,
and automatically speed up in steps as the temperature
rises. Do not block the vent holes to prevent
overheating.
3 – Thunderbolt Ports
Connect a Thunderbolt cable between either port and
your computer’s Thunderbolt port; the other may be
used to connect to another Thunderbolt device.
4 – BNC Connector Mounting Holes
These accommodate the installation of BNC
connectors like those used for HD/SDI output for the
RED ROCKET-X transcoding card.
5 – Power Input Socket
