Chapter 5 – Tips, General Information, and Known Issues

TIPS, GENERAL INFORMATION

Keeping the Cards Cool

With its optimized airflow design and temperature-controlled fan providing cooling at all times, the Echo III Rackmount provides adequate cooling for the installed cards. Do not operate the Echo module outside of its enclosure, and do not block any of the vents! Otherwise, the installed cards and Echo module's components may overheat.

Hot Plugging the Echo Module

When certified Thunderbolt-compatible cards (used with Thunderbolt-compatible drivers) are installed, you may connect and disconnect the module while the computer is on. Of course, if you have anything connected to the cards, such as storage devices, cameras, etc., follow proper procedures for disconnecting those devices before unplugging the Echo module.

There's No Need to Unplug the Power Cable

Because the Echo III Module automatically powers on and off with the computer to which it's connected, there's no power switch, nor is there any need to disconnect the power cable under normal use.

Power Indicator LED Operation

The module automatically powers on and off with the computer to which it's connected, and its power indicator only lights when the computer is on and turns off when the computer is sleeping or powered off.

Connecting Additional Thunderbolt Peripherals

The Echo module includes two Thunderbolt ports; the first is reserved for connection to your computer, while the second supports daisy-chaining of up to five additional Thunderbolt peripheral devices.

Using Expansion Cards Without Installing Drivers

Some Thunderbolt-compatible expansion cards, like Sonnet's Allegro™ Pro USB 3.2 PCIe cards, use inbox (built into the operating system) drivers, and are ready to use out of the box.

Replacing a PCIe Card After Initial Installation

Shut down the computer, and then disconnect the power adapter and Thunderbolt cables from the Echo III Module before opening the chassis and replacing the card; PCIe cards are not hot-pluggable!

Echo III Module Provides Downstream Power

The Echo module can provide up to 15 watts to bus-powered Thunderbolt peripheral devices, enabling them to operate without connecting an additional power adapter.

Using the Echo Module to Charge Your Portable Computer

MacBook Air ^® and MacBook Pro ^® with Thunderbolt ports, some PC laptop computers with Thunderbolt 3 ports, and all PC laptops with Thunderbolt 4 ports may be charged slowly via the Echo module's Thunderbolt port (via 15W Power Delivery). Computers with Thunderbolt 2 or Thunderbolt ports cannot be charged via Thunderbolt.

How to Identify Thunderbolt 3 (40Gbps) Cables

Look for the Thunderbolt icon (✗) AND the number 3 on the connector housings to identify these cables. Aside from Thunderbolt cables from Apple, USB-C cables with connectors that only have the Thunderbolt icon without the number 3 may only support 20Gbps speeds, and are not recommended for use with the Echo module. Cables marked with a generic USB icon (✗) are NOT compatible for connecting the Echo module to the computer.

Thunderbolt 4 Cable Compatibility

You may use Thunderbolt 4 cables with Thunderbolt 4 or Thunderbolt 3 computers and peripherals without any compromise in performance or functionality.

Not All Mac-Compatible Cards Work With M1 Max/M1 Pro/M1 Macs

While this product is compatible with M1 Mac computers, not all PCIe cards that work with Intel-based Macs have M1-compatible drivers. We recommend that you contact your PCIe card's manufacturer to verify that the existing drivers support M1 Macs.

KNOWN ISSUES

Not All Thunderbolt 3 Computers' Performance is Equal. While this product features a 40Gbps Thunderbolt 3 interface, some computers equipped with Thunderbolt 3 use an implementation of Thunderbolt 3 that limits PCIe performance to 20Gbps. Mid-2017 and earlier 13-inch MacBook Pro computers with four Thunderbolt 3 ports have this limitation in the two right-hand Thunderbolt 3 ports, while offering full performance from the left-hand ports.

Not all PCIe Cards Will Perform at 100%

Thunderbolt 3's PCIe bandwidth is limited to 2,750 MB/s. While most cards will operate at full performance, some may not because they require more bandwidth than Thunderbolt 3 can provide.

Not All Thunderbolt Cables Deliver Full Performance Full performance from the Echo module requires the use of the included (or comparable) Thunderbolt 3 (40Gbps) cable, or any Thunderbolt 4 cable. When shopping for a Thunderbolt 3 cable, please be aware that some support only lower data transfer speeds (20Gbps).

Operating System (OS) Updates May Break Compatibility Specific device drivers that work under one OS version may not work under a later version. Before updating your computer to the latest OS, we recommend that you contact your PCIe card's manufacturer to verify that the existing drivers work. Note that other computer software updates may also break compatibility.

Some Devices' Performance May be Affected by Where They Are Connected in a Thunderbolt Chain. However small, Thunderbolt introduces latency to a device chain. If you expand with additional Thunderbolt expansion chassis, you may need to experiment with which cards work better in chassis closer to or farther from the computer in the chain.
