Physical Installation

Figure 3: Physical installation of Crimson TNG hardware.

  1. Ensure the Micro SD card is fully inserted inside the Micro SD card reader.
  2. Plug in the power cable at the rear of Crimson TNG.
  3. Connect ethernet cable from host computer to Management port on front of Crimson TNG.
  4. Connect 10G SFP+ cables from 10GBASE-R network card installed in host computer to SFP+ ports on front of Crimson TNG.
  5. Turn on the unit and wait for the four LEDs on the front of Crimson TNG to light up. This is referred to as the LED Boot Sequence

LED Boot Sequence

When Crimson TNG is powered on, the four status LEDs next to the SD card will begin to light up. A normal LED sequence is shown in Figure 4.
