Outer Case
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 fans or the vent holes on the
front or back of the chassis to prevent overheating.

It is also compatible with PCIe 1.1 and 3.0 cards.
4 – Slot 2
This is an x8 electrical (x16 mechanical) PCIe 2.0
slot. It is also compatible with PCIe 1.1 and 3.0
cards.

moved to another slot.
7 – 6-Pin Auxilliary Power Connector
Plugged into this connector is the auxiliary power
cable for cards requiring extra power, such as the
Avid Pro Tools|HDX or RED ROCKET-X.
8 – PCIe Card Guides
When installing full-length cards, use these to
support and secure the cards.
9 – Thunderbolt Connector Retainer Clip
This secures a Thunderbolt connector plugged
into the Echo chassis’ Thunderbolt port to prevent
accidental cable disconnection. This clip is not
compatible with optical Thunderbolt cables.
