6.2 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
restart, please do the following:
1. If the system configuration is lost, configure the system again.
2. In the event of abnormal operation of the server, contact customer service for
technical support.
To avoid the above situations, please back up your data periodically and make sure
you have done the following:
z Follow the instructions described in Chapter 5.7.2 to restart or shut down the
server.
z If there is an anticipated power outage, back up all important data and turn off
the server properly until power supply is resumed.
6.3 Mirrored Disk Hot Swapping
NVR supports hot swapping. When a hard disk of RAID-1 mirroring disk volume
fails, the failed disk can be replaced by a new one immediately without shutting
down the system, and the recording data can be reserved. However, if the hard
disks are working properly and recording is in process, do not hot swap the disks to
avoid damage to the disks or recording files.
