Components of power supply units are under high voltage.
Touching conducting components of active power
supply units is forbidden.
When connecting the computer to the switch, remove
PoE jumpers at this port.
For effective operation of lightning protection is
required:
•high quality grounding according to the ELC;
•use of shielded twisted pair with shielded
connectors RJ45;
•Minimization of twisted pair and power cable length;

1. Designation
Device PSW-11- is a Multifunctional Gigabit Switch in street version designed
for connection of one IP-camera by optics. This switch has two ports. First
port is optical, the second - copper. The optical port is designed to connect it
to other switches (media converters), the second - to connect the video
camera.
Figure 1. Connection Scheme of the PSW-11
Weatherproof version
The body of the device is made of a techno-polymer that is resistant to
Stringent Operating Conditions. There is a protection from moisture and dust
IP66.
Operation in extreme temperatures
The device has industrial hardware components that are characterized by an
extended temperature range. Using industrial SFP modules in industrial
version guarantees operation from -55°C to 50°C.

5
Optical port speed selection
You can select optical port speed (1000M or 100M) with the jumper.
PoE Support
The switch can power any PoE-camera that supports IEEE802.3af standard.
Power supply for Camera housings over PoE
Switch operating with TFortis TH Camera housings powers both video
camera (IEEE802.3af) and Camera housing (Passive PoE) via twisted pair.
Connection to 220V
Built-in PSU provides direct connection of the switch to the Power Supply
220V and excludes need in additional PSU.
Lightning protection
Built-in Lightning protection of Ethernet ports and 220V PSU reliably protects
both the switch and connected video cameras from pulse disturbances
induced by lightning discharges.
Cold start
Preheating of camera housings provides safe and guaranteed turn-on of
video cameras in cold conditions.
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
The switch PSW-11 maintains power supply throughIEEE802.3af and Passive
PoE technology. Power supply is selected according to jumper configurations
(Table 2-3). Power is supplied through pairs 1,2 and 3,6 over data or through
free pairs 4,5 and 7,8. In the PoE standard terminology, first one is named as
mode A and the second - mode B. Power is supplied to video cameras installed
into TFortis TH camera housing using mode A and mode B simultaneously (I).
When you connect other devices (not PoE), remove jumpers for relevant port
(IV).

2.4 Optical port
The optical port of the switch is made in the form of a SFP slot, which
operates at speeds of 100Mbps or 1000Mbps, depending on the position of
the jumper FIBER.
2.5 Lightning protection
The switch has in-built lightning protection modules that provide protection of
Ethernet ports and power supply circuits ~220V from common-mode and
differential electromagnetic disturbances.
The switch is resistant to high-energy microsecond pulse interference
according to GOST R 51317.4.5 standard with a degree of rigidity according
to Table 2.5-1 with performance criteria B.
Switches are resistant to dynamic changes in the voltage of the AC
electrical network in accordance with standard GOST R 51317.4.11
according to Table 2.5-2 with the performance criteria B.

(Performance criterion B - temporary deterioration in the performance quality
or termination of the established function with the subsequent restoration of
normal functioning, carried out without the operator’s intervention)
Maintainability is preserved during fluctuations in supply voltage from ~ 187
to ~ 246 V
2.6 Cold start
The most critical moment in the operation of the video camera is the process
of its activation at low ambient temperature. Precisely a cold start can cause
the failure of an expensive video camera. To avoid such cases, the switch is
implemented with preheating of TFortis TH camera housings. The essence of
it is that after power is applied to the unit, initially will be powered heating
elements of camera housings, and only then in 1 hour the video camera itself.
This delay allows obtaining comfortable conditions for starting video cameras
and you will be able to save expensive equipment. This option is on by the
TIMER jumper.

12
2.7 Restart of video cameras at their hanging
Switch constantly monitors the intensity of the traffic from the video camera. If
the network activity is lost, the switch resets the camera by removing power
through PoE. This feature is enabled by setting AUTO RESTART jumper to
ON for a specific port.

5. Presetting
5.1. Configuring PoE on port
PoE power configuration is carried out using jumper (see section 2.3).
IMPORTANT! All connections must be made with the disconnected power
220V.
IMPORTANT! Remove the PoE jumpers for the port to which you will connect
the computer.
5.2. Speed mode configuration for SFP port
SFP port of the switch can operate at the speed 100М or 1000М. To set the
speed, set the FIBER jumper according to table 5-2
IMPORTANT! Optical SFP module with the declared speed up to 1.25 Gb
operates in 100Mand 1000Mmodes. An optical SFP module withthe declared
speed up to 155MGb operates only in 100M mode.
5.3. Enabling Preheating of camera housings
When the camera is turned on in the cold, it may not start or, even worse, fail.
To solve this problem, use the comfort start function. For this, you need to
install jumper TIMER in the position ON. After the power is turned on, the
preheating ofthe camera housing isswitched on. Moreover, after 1 hour, when
comfortable conditions will be created in the camera housing, a video camera
will be powered. By default, this function is disabled.
IMPORTANT! This function is available only with TFortis TH camera housings.

6. Device installation
6.1. Unit mounting
The enclosure has four attachment points along the edges of the unit. The
marking of the fastening for the installation of the product is shown on the Fig.
6.1.1.
Figure 6.1. Marking of the fastening
IMPORTANT! Drilling of the housing leads to a violation of the sealing of the
entire commutator and, as a consequence, the loss of warranty.
6.2. Optic connection
There are no elements for welding of the optical fiber inside the PSW-11. It is
recommended to use External Optical Distribution Frames.

15
6.3. Power connection
PSW-11 is connected to an AC source of 220V. The supply cable is brought
into the unit through the cable gland, where it is connected to the terminal block
of the power supply unit.
IMPORTANT! Grounding of the device is required. The ground resistance
must be no more than 4 ohms.
IMPORTANT! Do not allow circuit boards touching high voltage live wires.
Failure in this case entails a loss of product warranty.
IMPORTANT!
Since the switch contains switch-mode power supplies, it is a reactive load.
During start-up, when charging input capacitors, a startingcurrent appears and
it exceeds the nominal value. In order to avoid false alarms of the protection
devices, it is recommended to choose models with the characteristic C for a
current of at least 4A.
6.4. Connection of video cameras
The camera is connected to the switch using a twisted pair. It is recommended
to use a 4-pair shielded cable no worse than Category 5. When using the
TFortis TH camera housings, data transfer, powering video camera and
camera housing will be carried out by one cable, which eliminates the need to
use additional power cables.
