5. Operating Instructions
5.1 Power On/Off
To power on the enclosure, press the power button located on the rear panel. To power off, press and hold the power button until the unit shuts down. Always ensure data transfer is complete before powering off.
5.2 Disk Management
The enclosure supports individual disk access and replacement. You can eject a single disk without interrupting the workflow of other disk slots, allowing for quick replacement and upgrade. This feature is particularly useful for flexible storage management and regular backup of important files.
5.3 Daisy-Chain Functionality
The ORICO 9958C3 enclosure supports daisy-chaining up to three devices, expanding your total storage capacity to 330TB. To daisy-chain, connect the 'Hub' USB-C port of the first enclosure to the 'Main' USB-C port of the second enclosure, and so on. This creates a cascaded storage system for massive data projects.
