The TrueNAS ES24F is a 2U expansion shelf with 24 2�5” drive bays, SAS3 (12 Gb/s), dual expansion controllers, and
redundant power supplies�
Take a moment to review the safety considerations and hardware requirements before unpacking and installing an
ES24F into a rack�
1 Introducing the ES24F
1.1 Safety
1.2 Requirements
1�1�1 Static Discharge
1�1�2 Handling the System
The ES24F is a sensitive electronic device� Take full safety precautions when installing or servicing a system�
Static electricity can build up in your body and discharge when touching conductive materials� Electrostatic Dis-
charge (ESD) is very harmful to sensitive electronic devices and components� Keep these safety recommendations in
mind before opening the system case or handling system components:
1�
Turn off the system and remove the power cable before opening the system case or touching any internal com
-
ponents�
2� 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�
3� Touch the metal chassis with your bare hand before touching any internal component, including components
not yet installed in the system� This redirects static electricity in your body away from the sensitive internal com-
ponents� Using an anti-static wristband and grounding cable is another option�
4� Store all system components in anti-static bags�

It is recommended to have these tools available when installing an ES24F in a rack:
• #2 Philips head screwdriver
• Flathead screwdriver
• Tape measure
• Level
An ES24F that has no drives installed weighs 34�1 pounds�
It is always recommended to team lift an empty ES24F.
Do not attempt to lift an ES24F when it is fully populated with drives!
It is recommended to install the system in a
rack before adding drives and remove all drives before de-racking an ES24F�
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�
These instructions use “left” and “right” according to your perspective when facing the front of a system or rack�
