1. Technical description.
1.1.General description.
SF124 is a 24-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 G1/TP
and G2/TP ports is used for connection of another network device via RJ45 connector. The switch is fitted with SFP slots
(marked as G1/SFP and G2/SFP), the use of fiber optic module (GBIC) allows fiber optic transmission.The operating status of
the device (described in the table below) is displayed on the LED display on the front panel.
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.

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 30W per port is the maximum
value referring to a single output. The total power consumption should not exceed 240W 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. 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 the 230V AC power supply and turn on the device. The connection should be made with the supplied 3-core
cable with a plug. The place and method of installation of the switch should ensure free air flow around the unit.
2. Connect the camera wires to the RJ45 connectors (sockets RJ45 from 1 to 24).
3. Connect the remaining LAN devices to RJ45 connectors or SFP socket (G1/TP and G1/SFP or G2/TP and G2/SFP)
CAUTION! G1/TP and G1/SFP or G2/TP and G2/SFP connectors can not operate simultaneously!
4. Check the optical indication of switch operation (see Table 3).
