1 Introduction
The TrueNAS Mini R is a 2U Storage Array that has twelve (12) hot-swappable 3�5” drive bays and the option to
choose between rack or desktop mounting�
Your system comes with the TrueNAS operating system preloaded�
Review the safety considerations and requirements before handling the Mini R or installing it into a rack�
1.2 Requirements
We recommend these tools when installing a TrueNAS Mini R in a rack:
• #2 Phillips head screw driver
• Flat head screw driver
• Tape measure
• Level
1.1 Safety
1.1.1 Static Discharge
Static electricity can build up in your body and discharge when touching conductive materials� Electrostatic
Discharge (ESD) is harmful to sensitive electronic devices and components� Keep these safety recommendations in
mind before opening the system case or handling non-hot-swappable system components:
•Turn o the system and remove power cables before opening the case or touching internal components.
• Place the system on a clean, hard work surface like a wooden tabletop� Using an ESD dissipative mat can also
help protect the internal components�
• Touch the metal chassis with your bare hand to dissipate static electricity in your body before touching any
internal components, including components not yet installed in the system� Using an anti-static wristband and
grounding cable is another option�
• Store all system components in anti-static bags�
You can nd more preventative tips and details about ESD at https://www�wikihow�com/Ground-Yourself-to-Avoid-
Destroying-a-Computer-with-Electrostatic-Discharge�
We recommend at least two people lift a TrueNAS 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 whenever possible�
This document uses “left” and “right” according to your perspective when facing the front of a system or rack�
Never attempt to lift a TrueNAS system loaded with drives! Install the system in a rack before adding drives�
Remove drives before de-racking the system�

Release the locking arm by pushing the large circular button to the right� Fully open the locking arm, then gently grip
the top and bottom of the tray and remove it�
The Mini R supports iXsystems-qualied hard drives up to 18 TB. The Mini R also requires hard drives designed for
Network Attached Storage (NAS)� These drives run cooler and quieter than desktop drives� Please see the Drive
Compatability List available at https://www�truenas�com/truenas-mini/�
When ordered without hard drives, drive trays ship with protective ller inserts. If you don’t ll all bays with hard
drives, keep the llers in the empty trays to protect them.
5.2 Removing Drive Fillers
Remove the two rear screws holding the ller. Gently spread both sides of the tray away from the ller until the pins
release, then remove the ller.

7 Connect Network and Power Cables
Connect network cables from the router or switch to the gigabit networking port and the OOBM ethernet port�
Plug the power cable into the Mini R, then a power outlet�
7.1 Powering on the TrueNAS Mini
The Power and Reset buttons control the power state of the TrueNAS Mini� These buttons behave in the same
manner as standard PC power and reset buttons. When the system is o, pressing the power button turns the
system on. Pressing and holding the power button while the system is running performs a hard power o. The reset
button reboots the system�
By default, the Mini powers on as soon as you plug the cable into a live power source� In the event of power loss,
the Mini R also powers on as soon as power restores�
7.2 Notice: High Draw USB Devices
The current draw on the Mini power supply +5Vsb line can exceed specications if you leave high-draw USB
devices attached to the rear USB ports when the Mini R is powered o.
Unplug high-draw devices (such as bus-powered USB hard drives) before powering o your Mini R.

8 Console Setup
You can connect a VGA monitor and USB keyboard for console access, but they are not required� If a monitor and
keyboard are attached, you can see the Console Setup Menu� For more details about the Console options, see
https://www�truenas�com/docs/core/gettingstarted/consolesetupmenu/�
If you want remote out-of-band management (OOBM) via IPMI, connect a network cable to the IPMI port� See
section “2�2 Rear Components and Ports” on page 3 to nd your Mini IPMI port.
Your system is equipped with the optimal BIOS and IPMI rmware out of the box.
DO NOT UPGRADE your system’s BIOS and IPMI rmware.
We recommend that IPMI be on a separate and secure network without Internet access�
Please contact support if you need to upgrade your system’s BIOS or IPMI rmware.

Page 13
9 TrueNAS Web Interface
TrueNAS uses the Multicast DNS service, also known as Bonjour or mDNS, to make the system accessible on most
networks without additional setup�
Open a web browser on another computer on the same network� Open the TrueNAS web interface by navigating to
truenas.local (or your Mini R IP address)�
The TrueNAS web interface uses default credentials for rst-time logins:
Username: root
Password: abcd1234
After logging in, you can change the root account password in Accounts > Users to increase system security�
When more than one TrueNAS device is connected to the network, mDNS can experience name conicts. Give each
TrueNAS device a unique hostname like truenas1�local and truenas2�local to avoid the problem� You can change
hostnames in Network > Global Conguration > Hostname in the TrueNAS web interface�
Out-of-band logins have separate credentials from the TrueNAS web interface� The credentials are randomized and
attached to the back of the TrueNAS Mini R chassis� For more details, see https://www�truenas�com/docs/sb-327�
For more on Mini R Out-of-band Management� see: https://www�truenas�com/docs/hardware/mini/minieroobm/
If you want to run a dierent version of TrueNAS, you can nd new and legacy versions at truenas�com/download�
After downloading your desired version, you must use image utility like belenaEtcher or rufus to ash the ISO le to
a USB drive. Plug the ashed USB drive into a USB port on your Mini R and select it from from the boot menu during
system startup�
