1. Designation
SWD-1 –in Unmanaged Gigabit Switch with DIN-rail mounting. This device
has 4 ports for camera connections using PoE (see fig. 1-1). Where ports #4
and #5 support 1 Gigabit speed that allow to connect switches in a line
topology (see fig. 1-2)
PWR-48D –is a power supply unit with DIN-rail mounting. Designed for
powering SWD-1 switches from 230VAC. It is allowed to use one power
supply unit with two switches if the total power consumption ofvideo cameras
does not exceed 50W.

PoE support (IEEE802.3af)
The switch can power any PoE video camera that supports IEEE802.3af
standard. Power is supplied over free pairs (4,5 and 7,8)
Ease of installation
A compact modular body allows to install a switch and a power supply unit
on a DIN-rail into any cabinets. Next to them you can install circuit breakers,
residual current devices and other equipment. It’s convenient to lead all the
wiring through cable channels or under suspended ceiling.
Aesthetic design.
SWD-1 switch andPWR-48D power supplyunit can be installed into a plastic
switchboard panel and will successfully fit into any interior of office or house.

Gigabit ports
Due to the presence of two Gigabit ports, it is possible to connect switches
in a chain.
Informative indication
LED indicators are located on a front panel.
Cost effective port expansion
Two switches can be connected to PWR-48D power supply unit in case of
total power consumption of no more than 50W.

Automatic restart of video cameras at their hanging
The switch controls operation of video cameras. If video camera is hanging,
switch restart it automatically over PoE. This allows constructing non-
attended IP- video surveillance systems.

2.3. Power Supply over PoE
SWD-1 switch supports power supply using IEEE802.3af technology (4,5
and 7,8 pairs) for ports #1 .. #4. This eliminates the installation of separate
power cables.
2.4. CPU operation indication
During normal processor operation, the “RUN” indicator should flash with a
period of 2 seconds (1sec –on, 1 sec –off).
2.5. Restart of video cameras at their hanging
SWD-1 switch constantly controls traffic level (intensity) from the camera. If
the network activity falls below the set level the switch restarts the camera
by removing power from the PoE. This function is enabled by closing
contacts (fig. 2.5).

4. Operation conditions
The switch SWD-1 and PWR-48D power supply unit are intended for 24-hour
indoor operation in heated spaces at a temperature from +5 °С to +40 °С
and relative humidity up to 80%.
Mean time between failures for SWD-1 switch and PWR-48D power supply
unit is more than 50 000 hours (5-7 years).
The switch SWD-1 and PWR-48D power supply unit maintain declared
parameters at storage temperatures from -40 C to +50 C.
5. Device installation
5.1. Mounting
SWD-1 switch and PWR-48D power supply are mounted on a DIN-rail (35
mm)
5.2. Power connection
PWR-48D is connected to the AC source of 230VAC. SWD-1 switch is
recommended to connect to power supply unit with a short cable (no more
than 300 mm) with a cross-section no less than 0,75 sq mm. For stable
operation in the conditions with impulse noise it is recommended to arrange
grounding (no more than 4 Ohms).
5.3. Connection of video cameras
It is recommended to use a 4-pair shielded cable no worse than Category 5.
Ethernet cable is fanning out according to fig. 5.3.
