1 Unpacking the Unit
TrueNAS units are carefully packed and shipped with trusted carriers. If there is any shipping damage or any
parts are missing, please take photos and contact iXsystems support immediately at [email protected],
1-855-GREP4-iX (1-855-473-7449), or 1-408-943-4100.
Please locate and record the hardware “A1-”serial numbers on the back of each chassis (typically on the controllers’
locking arms) for quick reference.
Carefully unpack the shipping boxes and locate these components:
2 Become Familiar with the X-Series System
The X-Series has front panel indicators for power, locate ID, and fault. The fault indicator is on during the initial pow-
er-on self-test (POST) and turns o during normal operation. It turns on if the TrueNAS software issues an alert.
The X-Series has one or two storage controllers in a side-by-side conguration.

3 Rail Kit Assembly
On racks that are 30 inches deep or less, skip to “3.2 Rail Spring”.
3.1 Rail Extenders
Racks from 31 to 36 inches deep require installation of the included rail extenders. For these deeper racks, install
cage nuts on the outside rear of the rack. The tabs on the cage nuts must be horizontal as shown.
Using the included bolts, install the rail extender inside the rear of the rack. Repeat the process for the second ex-
tender, which is a mirror image of the rst.
3.2 Rail Spring
If not already present, install a spring on the silver posts in the side of each rail.
3.3 Attaching Rails to the Rack
Chassis rails are congured to attach to round hole racks. Additional pins are included in the accessory kit to
congure the rails for square or 4mm hole racks. To reset the rails to t a square or 4mm hole rack, unscrew the
pins at each end of the rails and replace them with the correct pins.
To secure a rail to the rack, open the clamp latches on the ends of each rail. Place the rail in the rack with the front
end toward the front of the rack, aligning the pins on both ends of the rail with the mounting holes in the rack.
Swing the clamp latch closed to hold the rail in place. Use two of the supplied screws to secure the back end of the
rail in place. Repeat the process for the second rail.
Caution: Two people are required to safely lift the chassis for rack installation or removal. Do not install
drives until after the chassis has been installed in the rack, and remove all drives before removing the chassis from
the rack. Carefully place the chassis onto the rails mounted in the rack. Push the chassis in until the ears are flush
with the front of the rack. If needed, attach the bezel. Use two of the supplied screws to secure each ear to the rack.
4 Install Drive Trays
Drive trays are used to mount drives in the chassis. Each drive tray has two status LEDs. The top LED is blue when
the drive is active or a hot spare. The bottom LED changes to amber if a fault has occurred.
A tray must be placed in each drive bay to maintain proper airflow for cooling. If fewer than twelve drives are con-
nected, empty “air baffle” trays must be placed in the empty bays.
A standard drive tray installation order simplies support and is strongly recommended:
• SSD drives for write cache (W), if present
• SSD drives for read cache (R), if present
• Hard drives or SSD drives for data storage
• Air baffle ller trays to ll any remaining empty bays
Install the rst drive tray in the top left drive bay. Install the next drive tray to the right of the rst. Install remaining
drive trays to the right across the row. After a row is lled with drives, move down to the next row and start again
with the left bay.
This example shows the proper order for a write cache (W) SSD, a read cache (R) SSD, eight hard drives, and two
empty air baffle trays.
To load an individual drive tray into a bay, press the blue button to open the latch. Carefully slide the tray into a
drive bay until the left side of the latch touches the metal front edge of the chassis, then gently swing the latch
closed until it clicks into place.
TrueNAS appliances only support qualied hard drives and SSDs. Contact the Sales Team if you need more drives
or replacements. Adding unqualied drives to the system voids the warranty. Call Support if drives are improperly
installed in trays.
4.1 Replacing Drives
Depending on the conguration ordered, X-Series drive trays come preinstalled with 3.5” drives, 2.5” drives with
adapter, 2.5” read intensive (RI) drives with interposer and adapter, and/or empty air baffles that preserve system
air flow. Drives that lose functionality can be removed from the tray and a new drive installed in its place or a sys-
tem upgraded by removing the air baffles and installing new drives ordered from iXsystems.
Place the tray on a flat surface and remove the four screws holding the drive to the tray, two on each side (1). Place
the new drive in the tray with the drive connector to the rear of the tray (2), and secure the hard drive in the tray
with four screws, two on each side. (3).
4.1.1 3.5” Drive Replacement
4.1.2 2.5” Drive Replacement
4.1.3 2.5” Read Intensive Drive Replacement
Place the tray on a flat surface and remove the three screws holding the adapter to the tray, two on one side and
one on the other (1). Remove the adapter from the tray and remove the two screws that hold the 2.5” drive to the
adapter (2). Follow this process in reverse to add the new 2.5” drive to an adapter and attach to the drive tray.
Warning: the interposer is considered part of the 2.5” drive and must be removed with it. Attempting to reuse an
interposer can result in a system malfunction or data loss!
Place the tray on a flat surface and remove the three screws holding the adapter in place, two from one side and
one on the other (1). Remove the adapter from the tray and remove the three screws that hold the 2.5” drive and
interposer in place, two from the side and one underneath the adapter (2). Gently lift the 2.5” drive and interposer
free from the adapter.
When installing the new drive, follow the previous procedure in reverse, but make sure the edge of the new inter-
poser slides under the retention tab (circled) on the adapter.
5 Connect Expansion Shelves
Expansion shelves connect to the HD mini SAS3 connectors on the X-Series. For detailed connection instructions
and diagrams, refer to the Basic Setup Guide included with your iXsystems TrueNAS expansion shelf or see the on-
line SAS Connections Guide. This example shows connecting an X-Series system with an ES24F
6 Connect Network Cables
Network cables vary by conguration and are not included. Please contact iX Support with any questions.
Connect network cables to the Ethernet ports and Out-of-Band (OOB) management port before powering on and
conguring the X-Series for the the rst time.
The Out-of-Band management port on the X-Series must be connected with a shielded Ethernet cable.
7 Connect Power Cord
If any TrueNAS expansion shelves are connected to the X-Series, power on the expansion shelves and wait at least
two minutes before connecting power cables to the X-Series.
Do not plug the power cords into a power outlet yet.
Connect a power cord to the back of one power supply, pressing it into the plastic clamp and pressing on the tab to
lock it in place. Repeat the process for the second power supply and cord.
After connecting both power cords to the X-Series, plug them into power outlets. The system automatically powers
on when connected to a power outlet. This design ensures that the X-Series powers back on after a power failure.
If you want to disconnect the physical power remotely, you can connect the X-Series to a remotely-managed Power
Distribution Unit (PDU).
9 Controller Removal and Installation
Warning: To avoid the potential for data loss, iXsystems must be contacted before replacing a controller or upgrad-
ing to High Availability. See section “14 Contacting iXsystems”.
9.1 Removing a Controller
Press in the blue clip on the bottom of the controller to release the two black locking levers. Swing the locking levers
outward and pull the controller out of the system.
8 Install Bezel (Optional)
The system does not require the bezel to operate. If desired, install the bezel by screwing in the bezel posts to the
system ears. The longer posts go in the top positions on the ears. Align the bezel with the posts on the chassis ears
and press it into place. To remove, grasp the bezel from the front and pull away from the chassis.
