Figure 3 5 Chapter 3 – PCIe Card Installation and Chassis Setup Steps WARNING: When handling computer products, take care to prevent components from being damaged by static electricity; avoid working in carpeted areas. Handle expansion cards only by their edges and avoid touching connector traces and component pins. Also, avoid touching the Echo Express SE III chassis’ circuit boards and any of its components. 7. Remove a PCIe card from its packaging, handling the card by its edges and without touching any components or gold connector pins. Support Note: If you are installing an x8 PCIe 1.1 card like certain 10 Gigabit Ethernet cards, installing it into slot 1 (furthest from the Thunderbolt interface card) may result in reduced performance. We recommend you install it into either slot 1 or 2 for best performance. 8. Line up the card’s connector with the slot, and then gently but firmly press the card straight into the slot; do not rock the card or force the card into the slot. If you encounter excessive resistance, check the card’s connector and the slot for damage, and then try inserting the card again (Figure 4). 9. Secure the card using the screw you removed Figure 4 previously; do not overtighten the screw (Figure 4). 10. Repeat steps 7 – 9 if you are installing any additional cards. Replace and secure any port access covers where an empty slot remains. 11. Flip the inner assembly back over to its upright position. Place your hand on top of the outer case, and then gently insert the inner assembly back into the outer case (Figure 5). 12. Turn the Echo Express SE III chassis upside-down, and then using the Figure 5 four screws you removed previously, secure the outer case to the inner assembly; do not overtighten the screws (Figure 6). Figure 6 6 Chapter 3 – PCIe Card Installation and Chassis Setup Steps 13. Turn the Echo Express SE III right-side-up. Support Note: Sonnet’s ThunderLokTM 3 Thunderbolt connector retainer clip secures the included Thunderbolt 3 (40Gbps) cable to the Echo chassis to prevent accidental disconnects. The included clip is compatible with Sonnet 0.7 and 0.5-meter Thunderbolt 3 (40Gbps) cables, but it is not compatible with Sonnet 2-meter Thunderbolt 3 (40Gbps) cables. To attach the clip to the cable, remove both items from their packaging, and then insert the connector through the connector clip as shown (Figure 7). Note that the connector will pass all the way through the clip; when you connect the cable to the chassis, the clip will secure the connector. 14. Connect the included Thunderbolt cable (or a comparable Thunderbolt 3 [40Gbps] cable) between a Thunderbolt 3 port on the Echo chassis and a Thunderbolt 3 port on your computer, or other Thunderbolt device in the chain connected to the computer (Figure 7). Note that cables or ports marked with the USB icon ( ) are NOT compatible. Secure the retainer clip to the chassis if you attached it. If you are daisy chaining additional Thunderbolt devices, connect Figure 7 another Thunderbolt cable between the downstream device and the open Thunderbolt port on the Echo chassis. 15. Connect the included power cord between a wall outlet or power strip and the power adapter; verify the connector is plugged in securely. Note that the power adapter’s power indicator will light at this time. 16. Connect the power adapter cable to the Echo Express SE III’s 12V power socket. Note that the power indicator on the Echo Express SE III chassis will not light until the computer, and any other Thunderbolt device connected between it and the Echo chassis, is powered on. 7
Chapter 4 – Complete Setup and Configuration SETUP AND CONFIGURATION STEPS This page instructs you how to verify the Echo chassis and installed cards are recognized by the computer. A – Confirm the Echo Express SE III is Recognized 1. With the Echo chassis powered and connected to the computer, turn on the computer. 2. Press and hold down the Option key, and then from the Apple menu, select System Information; a System Information window will open. 3. In the System Information window, click Thunderbolt under the Hardware header in the left column (Figure 8). 4. In the top right column under the Thunderbolt Device Tree header, you will see Thunderbolt Bus, and then “Echo Express SE-III TB3” (Figure 8). Support Note: If “Echo Express SE-III TB3” is not listed, disconnect and reconnect the Thunderbolt cable between the computer and Echo chassis. Note that it is not necessary to shut down the computer before disconnecting and reconnecting the cable, so long as the installed card is Thunderbolt-compatible. B – Confirm the Installed Cards are Recognized 1. In the System Information window click PCI under the Hardware header in the left column (Figure 9). 2. At the top of the right column, the installed cards are listed (if not, you may to install drivers before the cards are recognized). Click one of the cards; you should see “Yes” next to Driver Installed and Tunnel Compatible, otherwise the card or driver may not be Thunderbolt- compatible (Figure 9). Support Note: While the Echo Express SE III expansion chassis requires no drivers, installed cards require Thunderbolt-compatible drivers to enable their use. C – Install Card Drivers (If Necessary) 1. Launch a web browser, and then go to your card manufacturer’s website. Download and install the latest drivers according to the manufacturer’s directions. 2. Restart your computer; your Echo chassis is ready to use! 8 Figure 8 Figure 9
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, Echo Express SE III provides adequate cooling for the installed cards. Do not operate the Echo chassis with its cover off, and do not block any of the vents! Otherwise, the installed cards and Echo chassis’ components may overheat. Hot Plugging the Echo Express SE III When a certified Thunderbolt-compatible card (used with Thunderbolt-compatible drivers) is installed in the Echo chassis, you may connect and disconnect it 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 chassis. There’s No Need to Unplug the Power Adapter Because Echo Express SE III 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. Echo Express SE III Power Indicator LED Operation The chassis 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. Note that the power adapter’s power indicator remains lit as long as the adapter is connected to a live power outlet. Connecting Additional Thunderbolt 3 Peripheral Devices The Echo Express SE III includes two Thunderbolt 3 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 Drivers Some Thunderbolt-compatible expansion cards, like Sonnet’s AllegroTM Pro USB 3.1 PCIe and Sonnet’s Solo10GTM PCIe card, use drivers built into macOS, and are ready to use out of the box. Replacing a Card After Initial Installation Shut down the computer, and then disconnect the power adapter and Thunderbolt cables from the Echo Express SE III before opening the chassis and replacing the card. PCIe CARDS ARE NOT HOT-PLUGGABLE! Never install a PCIe card into Echo chassis while it is connected to a computer or power outlet! If you do, you risk injury, and damage to the card, chassis, and computer. Echo Express SE III Provides Upstream Power The Echo chassis can provide up to 15 watts to bus-powered Thunderbolt 3 peripheral devices, enabling them to operate without connecting an additional power adapter. 9 Using the Echo Chassis to Charge Your Notebook Computer Apple® MacBook Air® and MacBook Pro® computers with Thunderbolt 3 may be charged slowly via the Echo chassis’ Thunderbolt 3 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. Cables with USB-C connectors that only have the Thunderbolt icon without the number 3 support 20Gbps speeds, and are not recommended for PCIe cards with high bandwidth requirements. Cables marked with the USB icon ( ) are NOT compatible for connnecting the Echo chassis to the computer. KNOWN ISSUES Not All Computers’ Thunderbolt 3 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 40Gbps. While most cards will operate at full performance, some may not due to the fact they require more bandwidth than Thunderbolt 3 is capable of supporting. Not All Thunderbolt 3 Cables Deliver Full Performance Full performance from the Echo chassis requires the use of the included Thunderbolt 3 (40Gbps) cable (which also supports up to 100W power delivery), or a comparable Thunderbolt 3 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 Sonnet or your PCIe card’s manufacturer to verify that the existing drivers work. Note that other software updates for the computer 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.
