1. PRODUCT OVERVIEW
QTECH QSW-4700 series switches are new generation layer 3 switches, providing high
performance, consolidated security and multiple services. The switches are mainly applied to
the access layer to provide line-rate switching and complete QoS policies, prioritizing some
traffic over others to ensure important data transmission without lantency. The switches also
support a wide variety of Ethernet interfaces with flexible media options for network construction.

Note:
This is a Class A product. In a domestic environment this product may cause radio interference.
In this case, users are advised to take proper measures against the interference.
An SFP+ port supports both 10GBase-R and 1000Base-X.
The PoE+ port is backward compatible with the PoE standard.
•Management port: The management port is a 10/100/1000Base-T Ethernet port that
uses an RJ-45 connector. This port is connected to an Ethernet port of a PC with an
Ethernet cable for program downloading. You can manage and maintain the switch
remotely by connecting the management port to the Ethernet port of a PC with an
Ethernet cable.
•USB port: The USB port is the interface into which you plug your USB storage device
for online upgrade or log storage.
•Console port: The console port is an RS-232 port that uses an RJ45 connector. The
console port is used to connect a PC directly to the management system for debugging,
configuration, maintenance, management and program loading.

PoE
•All RJ45 ports are PoE+ capable and each port provides up
to 30 W of power. The maximum power depends on the
configured power supply.
•Note:
•The PoE+ port is compliant with both the PoE
(IEEE802.3af) and PoE+ (IEEE802.3at) standards.
•The maximum number of PoE devices supported by the
switch is determined by the available PoE consumption of
the switch and the actual PoE consumption of each device.
The PoE port is compliant with Alternative A.
Power

Without PoE Load: < 65 W
With PoE Full Load: < 810 W
Operating
Temperature
0ºC to 45ºC (32ºF to 113 ºF) at a height below 1800 m (1.12 miles)
above the sea level
At a height ranging from 1800 m (1.12 miles) to 5000 m (3.11
miles) above the sea level, the maximum operating temperature
decreases by 1°C (1.8°F) every time the altitude increases by
220 m (721.78 ft.).
