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.
Transportation of the switch with installed battery is
forbidden.
It is forbidden to connect over discharged batteries
(voltage at terminals is lower than 9.6V)
SFP module operates only at 1000 Mbit / s. Fast
Ethernet SFP modules will not operate.
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;
Modifications
•PSW-2G4F
•PSW-2G4F-UPS (with built-in uninterruptible power supply)
Note.
The text describesthe PSW-2G4F, thedistinctive featuresof the PSW-2G4F-
UPS are specified separately.

1. Designation
Device PSW-2G4F is an Outdoor Multifunction Gigabit Managed Switch
designed for networking of IP- video surveillance systems.
Figure 1. Connection scheme for the PSW-2G4F
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 65°C* (-67 to 149 F)*.
*The maximum temperature depends on the load (see diagram in section
4. Operation conditions)
High- performance Gigabit Switch
The basis of the switch is a high-performance chip from Marvell, which
provides processing of a large traffic coming from IР-video cameras.
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

5
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 housing 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 unattended
IP- video surveillance systems.
Operation in a ring and in a chain
With two gigabit ports, you can connect the switches in chain. STP/RSTP
protocol support allows creating ring topologies, what significantly increases
the fault tolerance of the system.
Uninterruptable power supply for the whole system
Since the switch PSW-2G4F-UPS has an uninterruptible power supply unit
and cameras operate via PoE, the whole system is reserved for power.
Resistance to the voltage 380V
When 380V is applied, the switch PSW-2G4F-UPS will switch to the battery
and keep the entire system working from the backup power source.

During normal operation of the processor, a CPU indicator must light
intermittently with a frequency of 2s. (1 sec. - on, 1 sec. - off.) DEFAULT
Indicator is on, when the device is in factory settings (IP 192.168.0.1).

2.3. Power Supply over PoE
The switch PSW-2G4F maintains power supply through IEEE802.3af 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).

IMPORTANT! There are two power units in the switch PSW-2G4F. Left one
supplies power to the video cameras and right one to camera housings. Make
sure that total consumption of video cameras does not exceed 50W. If TFortis
TH camera housings are not used, right PSU can be disconnected. Also, right
PSU can be used as left PSU backup (see 2.4 section)
