Solo10G Thunderbolt 3 Edition Description

  2. Link/Activity Indicator This LED flashes green to indicate a link is established between the adapter and the switch, and flashes yellow when the link is training.
  3. Link Speed Indicator When a link is established between the adapter and the switch, this LED lights to indicate the link speed to the switch: green = 10Gb; yellow = 5Gb, 2.5Gb, 1Gb, or 100Mb.

Basic Configuration Information–macOS
With the Solo10G adapter connected to your computer and network infrastructure, configure the adapter’s settings in the System Preferences’ Network preferences panel. The adapter will be identified as Thunderbolt Ethernet Slot x.

Performance Tuning Steps–macOS
Listed below are steps required to configure the Solo10G adapter for maximum performance. Please note that to take advantage of these settings, the switch or router to which the adapter is connected must also support these features.

  1. Open System Preferences, and then click Network. In the Network preferences panel, click the Solo10G adapter (Thunderbolt Ethernet, Slot x) in the left panel, and then click Advanced; a new panel appears.
  2. In the new panel, click Hardware. From the Configure dropdown menu, select “Manually”. In the Speed drop-down menu, leave the setting at or select “10GbaseT” (or “5000baseT” or “2500baseT” if either is the top speed your network connection supports). In the Duplex drop-down menu, select “full-duplex” (not “full duplex, flow-control”). In the MTU drop-down menu, select “Jumbo (9000)” or select “Custom,” and then enter “9000” in the box below.
  3. When you’ve finished changing the settings, click OK.
  4. Back in the main Network window, click Apply after you’ve completed changing the settings.

Basic Configuration Information–Windows
Configure the Solo10G adapter’s settings using Windows Device Manager. You may locate the device in the Network adapters category, listed as Sonnet Solo 10G Thunderbolt 3 Edition.

First Time Use–Windows
The first time you connect the Solo10G Thunderbolt 3 Edition adapter to your computer, an Approve New ThunderboltTM Devices window will appear. From the drop-down menu select Always Connect, and then click OK.

Basic Confiruration Information–Linux
The steps necessary to configure the Sonnet adapter with your computer may vary based on the version of Linux running. Sonnet recommends using whatever method or tools you would normally use for configuring any onboard ports.


5 Gb/s and 2.5 Gb/s Link Speed Support
The Solo10G supports 5 Gb/s and 2.5 Gb/s link speeds when used with NBASE-T compatible (multi-Gigabit) switches, and connected via CAT 5e (or better) cabling.

Solo10G May Become Very Warm While Operating
At times, the Solo10G may become very warm during operation; this is normal and does not indicate a malfunction. Due to the adapter’s design, its case may become very warm to the touch while transferring very large files or transferring a large amount of data over an extended period of time. The adapter may also operate at a higher than expected temperature when connected to a long cable run to the switch or storage system. Sonnet designed the Solo10G so that its case radiates heat away from the electronic components inside, ensuring they operate within a safe temperature range.

Solo10G Performance May Drop When Used With a Notebook Running on Battery Power
When the MacBook Pro’s or MacBook Air’s battery level drops below 20%, macOS will decrease Ethernet performance in order to conserve battery life.
Audio Video Bridging (AVB) Support
The Solo10G supports AVB when used with AVB-compatible (802.1Qav) switches.

Solo10G Requires a Thunderbolt 3 Port to Operate
The Solo10G T3E adapter is not compatible with the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter; the Sonnet adapter requires more power than a Thunderbolt 2 connection can provide.
