Elements of the power units are under high
voltage. It is strictly forbidden to touch conducting
elements of the power supply unit under voltage.
It is forbidden to transport the switch with the
battery installed in it.
It is forbidden to connect very low battery (voltage
at the terminals below 9.6V)
SFP port operates only at 1000 Mbps. Fast Ethernet
SFP modules will not operate.

1. Purpose
PSW-2G2F+UPS device is a multifunction gigabit outdoor managed switch
with built-in UPS designed for connecting IP video cameras with
IEEE802.3at (PoE+) support
one camera with 60W power consumption (Figure 1-1)

two cameras with 30W power consumption each (Figure 1-2)

Weatherproof design
The switch body is made of technopolymer resistant to severe operating
conditions. Dust and moisture protection rating is IP66. It is possible to
operate the device without additional enclosures.
Operation is a wide temperature range
The device is manufactured from industrial-type components and does not
need additional heating. The exceptions are batteries that are heating using
two heaters, which ensures operation of the device in the range from - 45
to +40C.
High performance gigabit switch
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.
PoE+ support for one port up to 60W
The switch supports IEEE802.3at power supply. Power can be supplied
either by pairs with data (pairs 1,2 and 3,6), or by free pairs (pairs 4,5 and
7,8) simultaneously. As a result, 60W can be supplied to the camera
(30W+30W).
PoE+ support for two ports, 30W each
The switch can support operation of two ports with 30W power for each
port.
Uninterrupted power supply for the whole system
Because the switch is equipped with UPS and cameras can be supplied by
PoE, the whole system has power backup.
Withstands the voltage of 380V
When 380V voltage is supplied to the switch, it will be supplied from the
battery and the whole system will continue to operate from the reserve
power supply.
Connection to 220V
A built-in power supply unit ensures direct connection of the switch to 220V
power supply, eliminating the need for additional power supply unit.
Lightning protection
A built-in lightning protection for Ethernet ports and 220V power supply
protects the switch and connected cameras from surges caused by
electrostatic discharges.

Automatic restart in case of camera hanging The switch controls
operation of the video camera. In case of hanging, the switch will restart the
camera automatically over PoE. It allows to create unattended IP video
surveillance networks.
Operation in a ring or in a chain configuration
Two gigabit ports allow to connect switches in a chain. Support of
STP/RSTP protocols allow to create ring topologies, which significantly
improves fault tolerance of the system.

During normal operation, CPU indicator should blink intermittently with 2
sec. period (1 sec. –ON, 1 sec. –OFF). DEFAULT indicator shall be ON,
when the device operates with factory settings (IP 192.168.0.1).

2.3. PoE power supply
PSW-2G2F+UPS switch supports IEEE802.3at power supply. The switch
can supply
either one camera with 60W power consumption (by default)

or two cameras with 30W power consumption each
Port 1 (60W)
Power is supplied by pairs 1,2 and 3,6 over data, and by free pairs 4,5 and
7,8 simultaneously. This way of power supply is implemented in powerful
video cameras with power consumption up to 60W.

2.4. Lightning protection
PSW-2G2F+UPS switch has built-in lightning protection modules that
protect Ethernet ports and 220V power circuits from common-mode and
differential electromagnetic interferences.
The switch is resistant to powerful microsecond pulse interferences
according to GOST R 51317.4.5 standard with the degree of severity
according to Table 2.4-1, performance criteria B.
The switch is resistant to AC transients in the power supply circuit
according to GOST R 51317.4.11 standard, Table 2.4-2, performance
criteria B.
