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 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.
Install GBIC’s to SFP sockets.
2. Connect switch to the PSD12020 12 V DC power supply unit desktop type.
3. Connect the power supply to the 230 V socket.
4. Connect devices to G1, G2 ports.
5. Check the optical indication of the switch operation (see Table 3).
