PDT-NSU-7216-PA-SF-R

16 Port 100/1000 BASE-T Passive PoE + 2 Port 100/1000 BASE-X SFP Unmanaged Switch 110-240VAC

The PDT-NSU-7216-PA-SF-R is an Unmanaged Gigabit AI Passive PoE switch, providing 16 x 10/100/1000 PoE (Hot +24VDC) ports and 2 x Gigabit SFP ports for connectivity, designed to directly connect to devices such as IP Cameras, Wireless APs, IP Telephones etc.

With AI VLAN Mode selected, Ports 1-16 are isolated from each other; all ports are only able to communicate with the Uplink ports when this option is enabled.  This can be useful when the network setup requires multiple clients to connect to a common resource but are specifically not required to communicate with each other.  This can reduce the effect of network storms, and can improve network security resilience.

With AI Extended Mode Selected, the effective transmission distance is increased from 100m to 250m, but the port speeds are reduced to 10Mbps; this limitation does not affect the uplink ports.  The AI Extend Mode is also suitable where the power source is too far away for conventional configurations, but the bandwidth limitation should not be overlooked when incorporating this feature into network designs.

AI Power Supply Mode allows the switch to check the ports periodically, for network activity.  If a port is not passing traffic for a period of time, the switch will automatically power cycle the PoE supply for that port.  The PD will then reboot and return to a functioning state, if it had failed or locked up. This is an ideal feature which can be used to automatically manage unstable peripherals, without the need for a site visit to recycle the device.

When AI QoS is enabled, all ports will prioritize video and VoIP traffic over other types. For example, in heavy network traffic, an IP Camera stream will be prioritized over a server backup stream, which may be essential for security or CCTV systems, where the integrity of the video signals is paramount.
