6. Installation and Maintenance
Installation
It is usually installed in the 3500 system rack. Attention should be paid to the power supply method (supports AC/DC combination) and the matching of rack slots. During installation, ensure that the ambient temperature (-40°C to +70°C) and protection level (IP65/IP67) meet on-site requirements.
Maintenance
The module is designed for easy maintenance and supports hot-swap. It is recommended to regularly check the data storage status and network communication, and ensure that the software and firmware versions are up-to-date.
