4 Handling Drives
When fewer than 24 drives are purchased with the system, air baffles are installed in all remaining drive tray slots.
To install new drive trays in the system, you can remove a baffle by inserting a flathead screwdriver in one of the
baffle grooves and gently pushing the baffle out of the slot. For proper airflow, it is recommended to keep all baffles
in place, unless new drive trays are being installed�
TrueNAS appliances only support qualified hard drives and SSDs. Contact the
if you need more drives
or replacements. Adding unqualified drives to the system voids the warranty. Call Support if drives are improperly
installed in trays�
