* The given value of 15.4W per port is the maximum value. The total power consumption should not exceed 48W when all PoE ports are being used.
2. Installation
2.1. Requirements
The unit should be mounted in confined spaces, in accordance with the 2nd environmental class, with normal relative
humidity (RH=90% maximum, without condensation) and temperature from -
10°C to +45°C. Ensure the free flow of air around
the unit. The PSU shall work in a vertical position that guarantees sufficient convectional air-flow through ventilating holes of the
enclosure.
The load balance should be done before installation Switcha. The given value of 15.4W per port is the maximum value
referring to a single output. The total power consumption should not exceed 48W when all PoE ports are being used.
The increased demand for power is particularly evident in the case of cameras with heaters or infrared illuminators - when
launching these features, the power consumption increases rapidly, which may adversely affect the operation of the switch. The
device is designed for a continuous operation and is not equipped with a power-switch. Therefore, an appropriate overload
protection in the power supply circuit should be provided. The electrical system shall be made in accordance with applicable
standards and regulations.
2.2. Installation procedure
1. Connect switch to the PSD480125 48VDC power supply unit desktop type.
2. Connect the power supply to the AC 230V socket.
3. Connect the camera wires to the RJ45 connectors (PoE connectors).
4. Check the optical indication of switch operation (see Table 3).
