1. Technical description.
1.1. General description.
SG108 is a 10-ports PoE switch designed to supply IP cameras operating in IEEE 802.3af/at standard.
Automatic detection of any devices powered in the PoE/PoE+ standard is enabled at the 1 – 8 ports of the switch. The UP LINK
ports is used for connection of another network device via RJ45 connector. The LEDs at the front panel indicate the operation
status (description in the table below).
The PoE technology ensures a network connection and reduces installation costs by eliminating the need to supply a
separate power cable for each device. This method allows supplying other network devices, such as IP phone, wireless access
point or router.

* The given value of 30 W per port is the maximum value. The total power consumption should not exceed 96 W.
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 +40 °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 switch load balance should be done before installation. The given value of 30 W per port is the maximum value
referring to a single output. The total power consumption should not exceed 96 W. 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. As 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 PSD520230 52 V DC power supply unit desktop type.
2. Connect the power supply to the 230 V socket.
3. Connect the camera wires to the RJ45 connectors (connectors PoE).
4. Check the optical indication of switch operation (see Table 3).
