1 Purpose
PSW-2G4F-Box is a multifunction gigabit outdoor managed switch used for
the construction of IP video surveillance networks.
Figure 1 - PSW-2G4F-Box connection scheme

2 Features
The switch enclosure is made of reinforced polycarbonate and is absolutely
corrosion-resistant. The switch design and fiber glass reinforcement provide the
maximum possible impact protection rating (IK10). Dust and moisture protection
–IP66.
The switch comprises industrial hardware with a wide range of operating
temperatures. Application of industrial SFP modules will ensure normal
operation in the temperature range from –60°C to 55°C* and above up to
+70°C* with less load (see diagram).
*The maximum temperature depends on the load (see diagram in section 5.
Operating conditions)
The key element of the switch is high performance chip from Marvell, which is
able to process a large volume of traffic coming from the IP cameras.
The switch may supply PoE to any camera compliant with IEEE802.3af
standard.
During operation with TFortis TH camera housings the switch uses a standard
twisted pair to power both the camera (IEEE802.3af) and the camera housing
(Passive PoE).
A built-in power supply unit ensures direct connection to ~230VAC power
supply, eliminating the need for additional power supply unit.
A built-in lightning protection for Ethernet ports and ~230VAC power supply
protects the switch and connected cameras from surges caused by electrostatic
discharges.

For safe and guaranteed start of video cameras in freezing weather, TFortis TH
equipment allows for preheating of camera housings.
The switch controls operation of the camera. In case of hanging, the switch will
reboot the camera automatically over PoE. It allows to create unattended IP
video surveillance networks.
Two gigabit ports allow to connect switches in a chain. Support of STP/RSTP
protocols allows to create ring topologies, which significantly improves fault
tolerance of the system.
The switch enclosure has a tamper sensor (a sealed switch). The cabinet door
opening will generate an alarm message to be sent to the server via SNMP or
Syslog protocols.
The optical distribution frame allows for optical cable splicing inside the switch
and connecting it to SFP modules.
A 35 mm DIN rail is provided inside the switch to allow installation of additional
equipment.

3.4.2 230VAC power supply backup jumpers
PSW-2G4F-Box switches have two power supply units. The left PSU is
designed to supply power to the switch and video cameras over PoE. The right
PSU has two operating modes selected by RES_PWR jumper according to
Table 3.4.2.

IMPORTANT!
If RES_PWR is put into the NO position, make sure that when you connect
devices that do not support PoE (for example, a PC), PoE jumpers for the
corresponding port (IV) are removed (see Section 3.4.1).
3.4.3 CPU button
To restart the switch, press the CPU button shortly.
3.4.4 DEFAULT button
To restore factory settings, press the DEFAULT button and hold it down for
about 30 seconds. The DEFAULT indicator should set ON at this point.
3.4.5 CPU indicator
During normal processor operation, the CPU indicator should blink in 2-second
intervals (1 second ON, 1 second OFF)
3.4.6 DEFAULT indicator
DEFAULT indicator is ON when the device has the factory settings (IP
192.168.0.1).

14
3.4.7 PoE indicators
The PoE A indicator is ON when power is supplied over data (pairs 1, 2 and 3,
6). The PoE B indicator is ON when power is supplied by free pairs (pairs 4, 5
and 7, 8).
3.4.8 LINK indicators
Blinking of LINK indicators show that data are transmitted via the corresponding
port.
3.4.9 Power indicators
Power indicators show the presence of supply voltage on the switch boards.
3.5 Dry contact
On the switch board there is a dry contact –SENSOR 1 digital input. This port
can be used to connect a relay output of the user equipment. Its actuation will
generate an alarm message sent to the server via SNMP Traps, SMTP or
Syslog protocols (see detailed information in the Configuration Manual).
Figure 3.5 - Dry contact.
3.6 Tamper sensor
The switch enclosure has a tamper sensor (a sealed switch). The sealed switch
is connected to SENSOR 2 contact. The cabinet door opening will generate an

15
alarm message to be sent to the server via SNMP Traps, SMTP or Syslog
protocols (see detailed information in the Configuration Manual).

3.7 Integrated lightning protection
PSW-2G4F-Box switch has built-in lightning protection modules that protect
Ethernet ports and ~230VAC power circuits from common-mode and differential
electromagnetic interferences.
The switches are resistant to powerful microsecond pulse interferences
according to GOST R 51317.4.5 standard as per Table 3.7.1 with performance
criteria B (temporary disruption of performance or functioning with further
recovery without operator's intervention).

IMPORTANT!
Grounding of the switch is mandatory for lightning protection.
3.8 DIN rail and automatic circuit breaker
A 35 mm DIN rail is provided inside the switch to allow installation of additional
equipment.

3.9 Automatic circuit breaker
The switch is provided with an automatic circuit breaker for ease of
maintenance.
3.10 Additional functions
3.10.1 Cold start
The most critical moment in camera operation is its start at low temperature.
Cold start may result in failure of an expensive camera. To prevent that, TFortis
TH camera housings of PSW-2G4F-Box switch have a preliminary heating
function. When power is supplied, it first goes to the heating elements in the
camera housing, 1 hour later the camera itself it supplied. This delay provides
comfortable conditions for the camera start and prevents failures of expensive
equipment. The Comfort Start option is available via the web interface in the
Special Function section (see the Configuration Manual).
IMPORTANT!
The Cold Start function is available only for TFortis TH camera housings.
3.10.2 Restarting cameras in case of hanging
PSW-2G4F-Box continuously monitors connection of the camera to the switch.
There are three ways to detect camera hanging:
No connection to the camera (Link)
No response to service requests (Ping)
Reduction of port speed below the established limit (Speed)

18
The switch continuously (once a minute) monitors the Link signal from the IP
camera. If the switch fails to detect the Link signal, then a one-minute timer is
started, and after that the connection is monitored again. If the Link signal does
not appear, the switch removes power for 10 seconds and supplies it again,
rebooting the camera. In other words, if the switch fails to see the Link signal
from the camera twice in succession at an interval of 1 minute, it reboots the
camera. The Auto Restart option is available via the web interface in the Special
Function section (see the Configuration Manual).
The switch constantly (1 time per minute) polls the IP camera. If the switch does
not receive a response, then a one-minute timer is started, during this time the
poll is repeated every 10 seconds. If the camera has not responded within a
minute, the switch removes power from the camera for 10 seconds and supplies
it again, rebooting the camera. If the camera has responded at least once, the
switch makes a decision that the camera is functional and starts the poll cycle
again, polling the camera 1 time per minute. The Auto Restart option is
available via the web interface in the Special Function section. To use this
function, it is necessary to enter the IP address of the camera. Make sure your
camera responds to PING (see the Configuration Manual).
The switch continuously monitors the speed on the port the camera is
connected to. If the flow speed goes below the established limit and fails to
restore, the switch makes a decision that the camera is hanging and reboots it.
The user may specify the limit values (see the Configuration Manual).
3.10.3 Cable tester
The switch has the functions of a virtual cable tester (VCT), which allows to
determine the breakage of the twisted pair, short-circuiting the wires of the
twisted pair, unconnected cable to the camera, the distance from the switch to
the fault. The cable tester diagnoses pairs that transmit data (1, 2 and 3, 6).
Note that the accuracy of the cable tester is ± 2 meters.
Video camera restart using Link signal
Camera restart due to no response to Ping request
Camera restart in case of port speed reduction

19
By default, VCT operates on an average algorithm and does not take into
account the specific features of a particular cable, which can affect the accuracy
of the measurement. To improve the accuracy of the cable tester, it is
recommended to calibrate it. Note that calibration is not recommended for
cables shorter than 10 meters.
3.10.4 Remote camera polling
Using the switch, it is possible to ping any device on the network through the
web interface, which is convenient when solving network problems.
