Echo Express SEL Inner Assembly
1 – Thunderbolt Interface Card
This is installed into its own slot and
may not be moved to the PCIe slot.
2 – PCIe Slot
This is an x8 mechanical (x4 electrical)
PCIe 2.0 slot. It is also compatible with
PCIe 1.1 and 3.0 cards. Note that the
use of a low-profile bracket on the
card installed into the slot is required.
3 – Fan
The temperature-controlled fan
provides cooling for the installed
PCIe card and the chassis’ supporting
Thunderbolt circuitry. It operates at
a whisper when the card is running
cool, and speeds up when the
temperature rises. Do not block the
vent holes on the back of the chassis
to prevent overheating.
Echo Express SEL Power Adapter
1 – Power Adapter
Connect this to the Echo Express SEL
chassis’ power port. Note that the
power indicator on top lights when
the adapter is connected to AC power.
2 – Power Cord
Connect this between a power outlet
and the power adapter. Note that
the power cord included with your
product may appear different than
the one pictured here, depending on
where the product was purchased.
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.
Thunderbolt Cable
Connect this cable between the
Echo chassis and your computer
(or other Thunderbolt
device in the chain
connected to the
computer).
