1 Introduction The TrueNAS R20 is a 2U, 12-bay, hybrid storage array with redundant power supplies. Your system comes with the TrueNAS operating system preloaded. Review the safety considerations and requirements before interacting with the R20. Drive Slots Power Expansion...
Warning - PPE Wear proper PPE, like anti-static wrist straps and smocks before touching any sensitive equipment inside the chassis. If you are unsure how to properly replace any parts, contact iXsystems Support. 2.4 Handling the System Hold the system from the sides or bottom whenever possible. Always be mindful of loose cabling or connectors, and avoid pinching or bumping these elements.
5 Space Requirements Note - Rack Space The R20 requires 2U of rack space and a #2 Phillips head screwdriver to install in a rack. The system is 26” (66 cm) long. Rack posts must be 23” - 35.75” (58.4 cm-90.8 cm) apart to install the rail kit. You must have at least 27”...

7 Racking Procedure 7.1 Remove Chassis Rail from Rack Rail The rail kit separates into two pieces, the inner chassis rail and the outer rack rail. Slide the chassis rail out of the rack rail until it stops, then push the metal safety catch and remove the chassis rail. Press Chassis Rails...
7.2 Install the Chassis Rail on the System Fit the rail keyholes over the mounting pegs on the system and slide the rail toward the back of the system until it locks. Use a round M4 rail screw to secure the rail to the chassis. Repeat the process for the second chassis rail. Round M4 Screw Page 7...
7.3 Install the Rack Rail in the Rack Align the rail end stamped “FRONT” with the front of the rack. Face the “FRONT” text inside the rack so the chassis rails can slide into the rack rails. Align the rail front pegs with the top and bottom holes in the bottom 1U and push the rail into the holes until the spring latch locks the rail in place.
7.4 Install the System in the Rack Team-lift the system and align the chassis rails with the rack rails. Slide the ends of the chassis rails into the rack rails and push the system into the rack until the metal safety catches on the chassis rials click and lock the system into place.
7.5 Secure the System to the Rack The rail kit includes several round M5 rack screws you can use to secure the chassis ears to the rack. Push in the hinged doors on each ear to open them, then install the round M5 rack screws. Mounting Mounting Screw...
7.6 Install Drives Tip - Drive Population We recommend a standard drive tray installation order to simplify support: • SSD drives for write and read caches (if present) • HDDs or SSDs for data storage • Air baffles for remaining empty bays (if present) Install the first drive in the top left bay.
7.7 Install Bezel Align the right side of the bezel with the attach points on the right ear, then push the left side of the bezel into the attach points on the left ear until it clicks and locks into place. Page 12 v.25021...
7.8 Install Cables Connect one ethernet network cable from your local switch or management network to the Out-of-Band Management (OOBM) port, and another one to the first 1GbE ports (port 1) on both controllers. Next, connect a monitor and keyboard to the VGA and USB ports on the same controller. Finally, connect the power cables to both power supplies, then plug them into a power distribution unit.
7.8.1 10/40/100GbE NIC Cabling If you ordered your system with a 10, 40, or 100GbE NIC, you can connect the SR4 cables now. Insert SR4 optics into the bottom port with the gold connectors facing left, then plug the SR cable into the optics. Repeat for the other port.
7.8.2 10G Base-T NIC Cabling If you ordered your system with a 10, 40, or 100GbE NIC, you can connect the SR4 cables now. Insert SR4 optics into the bottom port with the gold connectors facing left, then plug the SR cable into the optics. Repeat for the other port.
7.8.3 1/10/25GbE or Fibre Channel NIC Cabling If you ordered your system with a 1, 10, or 25GbE NIC, or a Fibre Channel NIC, you can connect the SR cables now. Insert SR optics into the bottom port with the gold connectors facing left, then plug the SR cable into the optics. Repeat for the other port.
7.8.4 Expansion Cabling If you ordered your system with an expansion shelf, you can set up the SAS3 cable now. Line the SAS3 cable connector up with the SAS port on the back of the system. Ensure the blue tab on the SAS cable is facing up. Gently push the connector into the port until it clicks. See “8 SAS Connections”...
7.9 Boot the System After plugging the power cables into outlets, the system powers on and boots into TrueNAS. When booted, the system console displays the TrueNAS web UI IP address, which is either preconfigured according to customer guidelines or automatically generated with DHCP. Enter the IP address into a browser on a computer on the same network to access the web user interface.
8 SAS Connections Important - SAS Configuration When setting up SAS connections, please adhere to the wiring example below. Connecting Expansion Shelves incorrectly causes errors. Never cable a single controller to different IOMs/expanders on the same shelf. 8.1 ES24 R20 connected to one ES24 shelf. 12Gb/s 12Gb/s Page 19...
