Echo I Module Interior
1 – Auxilliary Power Connectors
When auxiliary power is required, these connectors provide power to
the installed card.
2 – PCIe Card Slot
This is an x16 mechanical (x4 electrical) PCIe 3.0 slot. It is also
compatible with PCIe 4.0, 2.0, and 1.1 cards.
3 – PCIe Slot Access Cover
Remove this cover when installing a double-width card. If a single-width
card is installed, leave this in place.
4 – Temperature-Controlled Fans
These provide cooling for the installed card and the module’s supporting
Thunderbolt and power circuitry. They operate at a whisper when
the cards are running cool, and automatically speed up in steps as the
temperature rises. To prevent overheating, do not block the fans or the
vent holes on the module.
