Vivotek ND9542P 32-Channel 4K UHD NVR (No HDD) - Manual (Page 23)

VIVOTEK - Built with Reliability
User's Manual - 23
1. The onboard DHCP server provides IPs for the connected PoE cameras (10.1.1.1 or
192.168.2.1 onward). The uplink Ethernet port acquires a different IP from the network it
connects to. The PoE ports and the uplink are in the separated networks.
If your uplink port happens to connect to a 10.1.1.x network, make sure you change your PoE
subnet to 192.168.2.x segment.
Although the system supports MAC Binding, the system should be able to detect VIVOTEK's
cameras within the network regardless of the presence of a DHCP server.
NOTE:
2. Note on external storage enclosure via the USB 3.0 interface (the upper port):
2-1. If external USB 3.0 storage is attached, a max. volume size of 16TB is supported. The
NVR supports the connection to a USB3.0 storage with a maximum of 5 disk drives. The
minimum storage size in the external storage is 64GB.
2-2. The external storage must be powered on first before the NVR.
2-3. Hot-swapping is not supported. If the external storage is disconnected, recording will be
continued using the NVR's internal disk drives.
2-4. The storage configuration on the external storage is separately configured, e.g., RAID
configuration. The RAID volume on the external storage appears to the NVR as a single
large disk drive, and you should create a volume from it from the Storage configuration
page.
2-5. If the disk drives in the external storage are not configured into the NVR's storage
volumes, you can use them as the external backup devices. To do so, you should format
disk drives in the external storage in the FAT32 or NTFS format, and export the recorded
video on NVR to these disk drives.
