PSW-2G4F

PSW-2G4F-UPS

Multifunctional Gigabit Managed Switch for IP- video

surveillance systems

Version 7

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

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.

2.2. Element arrangement

Figure 2.2-1. Element arrangement of the PSW-2G4F

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)
