1 Purpose
PSW-2G6F+UPS-Box is a multifunction gigabit managed outdoor switch with
a built-in UPS, built-in optical distribution frame and PoE+ support designed for
building IP video surveillance networks.
Figure 1 –PSW-2G6F+UPS-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.
Weatherproof design

5
The switch is built based on industrial hardware with a wide range of operating
temperatures. Application of industrial SFP modules ensures normal operation
in the temperature range from minus 60°C to plus 50°C.
The key element of the switch is high performance Marvell chip, which is able to
process a large volume of traffic coming from the IP cameras.
All ports support PoE+ (IEEE802.3at). Ports 1 and 2 support double PoE+,
which makes it possible to provide 60 W using a standard twisted pair. This
feature is extremely useful for energy-consuming PTZ cameras.
During operation with TFortis TH camera housings, the switch uses a standard
twisted pair to power both the camera and the camera housing via PoE. For
safe and guaranteed start of video cameras in freezing weather, TFortis TH
equipment allows for preheating of camera housings.
The entire system has power backup, because the switch is equipped with UPS
and the cameras can be supplied by PoE.
If 380V voltage is supplied to the switch, the switch will be powered from the
battery and the whole system will continue to operate from the backup power
supply.
The optical distribution frame allows for optical cable splicing inside the switch
and connecting it to SFP modules.

A built-in power supply unit ensures direct connection to 230VAC power supply,
eliminating the need for additional power supply units.
A built-in lightning protection for Ethernet ports and 230VAC power supply
protects the switch and connected cameras from surges caused by electrostatic
discharges.
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). Opening of the
cabinet door will generate an alarm message to be sent to the server via SNMP
or Syslog protocols.

3.7 Integrated lightning protection
PSW-2G6F+UPS-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 Additional functions
3.8.1 Cold start for TFortis TH camera housings
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 PSW-
2G6F+UPS-Box switch has a preliminary heating function of TFortis TH camera

17
housings. 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.
3.8.2 Restarting cameras in case of hanging
PSW-2G6F+UPS-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)
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 checked 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
Video camera restart using Link signal
Camera restart due to no response to Ping request

18
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).
3.8.3 Cable tester
The switch can function as a virtual cable tester (VCT), which allows to
determine the breakage of the twisted pair, short-circuiting of the twisted pair
wires, cable disconnection from the camera, distance from the switch to the
fault. The cable tester is used to test pairs that transmit data (1, 2 and 3, 6).
Note that the accuracy of the cable tester is ± 2 meters.
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.
3.8.4 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.
3.9 Built-in UPS
The built-in UPS is a separate removable compartment that includes a metal
housing with a backup battery inside it. In the bottom of the compartment, there
is a heating element. Radiators and heat-insulating pads provide uniform
heating of the battery in cold weather conditions. The UPS board has a
thermostatic element that allows to maintain the temperature required for proper
battery operation.

3.9.1 Switching to battery power
The switch controls 230 VAC input voltage. If the input voltage is above 260V or
below 180V, the switch is disconnected from the external power supply and
operates from the battery power.
IMPORTANT! Switching to battery power does not cause interruption in
operation of the switch.
Deviations in the external power supply may be caused by:
phase imbalance
loss of neutral (380 V)
socket error (380 V)

IMPORTANT! When the power is turned on, the ALARM indicator always
lights up. Only after 5-10 seconds the device goes into normal operation mode.
3.9.2 Battery charging
When 230 VAC external power supply is available, it will power the switch and
at the same time charge the battery. Charging is implemented in two stages.
First, the battery is charged by direct current (CC=1A). With the increase in
battery power, battery voltage increases too. As soon as it reaches 27V,
charging converts to direct voltage (CV=27V). In this mode voltage gets stable
and current drops with the increase in battery power. This approach ensures
faster and more effective battery charging.
Figure 3.9.2 –Dependence of direct current and voltage on the battery power.
3.9.3 Battery discharge
In case of backup power supply, battery voltage drops from 27 V to the nominal
24 V, then the battery discharges gradually. At this stage the battery releases
most of its power.
