7.2 Power Outage or Abnormal Shutdown
In case of power outage or improper shutdown of the server, the server will resume
to the state before it is shut down. If your server does not function properly after
the restart, please do the following:
1. If the system configuration were lost, configure the system again.
2. If the problem persists, contact the technical support.
7.3 Hot Swapping Hard Disk Drives (RAID Configuration)
This function is not supported by the one-bay NVR models.
When a hard disk drive (HDD) of a RAID configuration fails, the failed HDD can be
replaced by a new one immediately without shutting down the server, and the
recording data can be reserved. However, if the HDD are working properly and the
recording is in process, do not hot swap the HDD to avoid damage to the HDD or
recording files.
Warning: You are strongly recommended to turn OFF the server before replacing
the HDD to reduce the risk of electric shock.
