GSW-1820VHP
3
In the Extend operation mode, the GSW-1820VHP operates on a per-port basis at 10Mbps duplex operation but can support 20-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-1820VHP provides an additional
solution for 802.3af/at PoE distance extension, thus saving the cost of Ethernet cable installation. Its VLAN isolation function isolates ports so as to prevent
broadcast storm and defend DHCP spoong in the Extend operation mode.

Flexible Extension Solution
The two mini-GBIC slots built in the GSW-1820VHP is compatible with the 1000BASE-SX/LX SFP (small form-factor pluggable) fiber transceiver, uplinked to
the 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.
Robust Protection
The GSW-1820VHP provides contact discharge of ±6KV DC and air discharge of ±8KV DC for Ethernet ESD protection. It also supports ±6KV surge immunity
to improve product stability and protects users’ networks from devastating ESD attacks, making sure the ow of operation does not uctuate.
