GSW-1820HP
Ethernet Data Transmission Distance Extension
The DIP switch provides “Standard”, “VLAN” and “Extend” operation modes.
■TheGSW-1820HPoperatesasanormalIEEE802.3atPoE+switchinthe“Standard”operationmode.
■The“VLAN”operationmodefeatureswithport-basedVLANfunctionthathelpstopreventtheIPcamera’smulticastorbroadcaststormfrominuencing
each other.
■Inthe“Extend” operation mode, the GSW-1820HP operates on a per-port basis at 10Mbps duplex operation but supports 22-watt PoE power output
over a distance of up to 250 meters overcoming the 100m limit on Ethernet UTP cable.
With this brand-new feature, the GSW-1820HP provides an additional solution for 802.3at PoE+ distance extension, thus saving the cost of Ethernet cable
installation.

Energy-saving Design
The GSW-1820HP uses new engine that incorporates two advanced Green Networking technologies:
■ Idle Mode Link Down power savings
■ Intelligent Scales Power based on cable length
TheIdlemodeLinkDownpowersavingsoftheGSW-1820HPcomplieswithIEEE802.3azEnergyEfcientEthernet(EEE)standardtoautomaticallylower
power for a given port when it is not linked. The Intelligent Scales Power technology actively determines the appropriate power level based on the cable
length. When connecting to the GSW-1820HP with Ethernet cable shorter than 20m, a device can obtain maximum power savings because the GSW-
1820HP would automatically detect the Ethernet cable length and reduce power usage. The connected device can substantially reduce the overall power
consumption,whichmakesasignicantcontributiontoenergysavings.
Flexible Extension Solution
Thetwomini-GBICslotsbuiltintheGSW-1820HParecompatiblewiththe1000BASE-SX/LXSFP(SmallForm-factorPluggable)bertransceiver,uplinked
to backbone switch and monitoring center in long distance. The distance can be extended from 550 meters (multi-mode fiber) to 10/20/30/40/50/60/70/120
kilometers(single-modeberorWDMber).Theyarewellsuitedforapplicationswithintheenterprisedatacentersanddistributions.
