16-Port 10/100/1000T 802.3at PoE + 2-Port 1000X SFP
Gigabit Ethernet Switch
Centralized Power Management for Gigabit Ethernet PoE Networking
To facilitate 30W PoE power network applications with Gigabit speed
transmission, the GSW-1820HP is equipped with 16 10/100/1000BASE-T Gigabit
Ethernet ports and 2 1000BASE-X SFP interfaces with the inner power system.
With a total of 240 watts of PoE budget, it features high-performance Gigabit
IEEE 802.3af PoE (up to 15.4W) and IEEE 802.3at PoE+ (up to 30W) capabilities
on all ports.
By offering reliable switching technology and advanced networking features,
the GSW-1820HP optimizes the installation and power management of network
devices such as wireless access points, VoIP phones, and security cameras.
It also eliminates time and cost of deployment by integrating power and data
switching into one unit and freeing network devices from restrictions of power
outlet locations and the additional AC wiring.
Physical Port
• 16-port 10/100/1000BASE-T Gigabit RJ45 copper with
802.3at PoE+ injector function

span PSE
• Up to 16 ports of IEEE 802.3af/802.3at devices powered
• Supports PoE power up to 30 watts for each PoE port, all
power up to 240W PoE budget.
• Each port supports 52V DC power to PoE powered device
• Auto detects powered device (PD)
• Circuit protection prevents power interference between
ports
• Remote power feeding up to 100m
Switching
• Hardware-based 10/100/1000Mbps auto-negotiation and
auto MDI/MDI-X

• IEEE 802.1Q VLAN transparency
• Hardware DIP switch for Standard, VLAN and Extend
mode selection;
– VLAN mode: Ports 1 to 14 cannot communicate with
each other, but can communicate with the uplink ports
15 to 16 and SFP ports 17 to 18
– Extend mode: Ports1 to 8 have data rate of 10Mbps.
The farthest transmission distance up to 250 meters and
all ports can communicate with each other.
• The DIP switch can isolate ports to prevent broadcast
stormanddefendDHCPspoong

– Link down power savings
– Intelligent use of power based on cable length
Perfect Integrated Solution for PoE IP Surveillance
The GSW-1820HP brings an ideal secure surveillance system at a lower total
cost. The GSW-1820HP provides 16 10/100/1000Mbps 802.3at PoE+ ports able
tofeedsufcientPoEpowerfor16IEEE802.3af/IEEE802.3atPoE+IPcameras
at the same time. It is also able to connect with one 16-channel NVR or two
8-channel NVRs, uplinked to backbone switch and the monitoring center. With
suchhigh-performanceswitcharchitecture,therecordedvideolesfromthePoE
IP cameras can be saved to the NVR system where the administrator can control
and monitor the surveillance images in both the local LAN and remote sites.
