3.3 Product Application
3.3.1 Airport & Train Station
IEEE 802.3at Compliant IP Surveillance and Wireless Powered Devices
Having the capability of IEEE 802.3at Power over Ethernet standard, the GSD-
808HP can directly connect with any IEEE 802.3at end-nodes like PTZ (Pan, Tilt
& Zoom) network cameras, PTZ Speed Dome cameras, color touch- screen
Voice over IP (VoIP) telephones, and multi- channel wireless LAN access points.
Besides the wired Internet network, the wireless LAN would be more efficient for
the transportation station to provide high-speed and wide area Internet services
for travelers. By adopting PoE Wireless LAN structure, the transportation authority
gains benefit from less cost while providing better Internet services in wider areas
for the travelers.

Cable distance for Switch
The cable distance between the GSD-808HP and PC should not
exceed 100 meter for UTP/STP cable.
Make sure the wiring is correct
It can be used Category 3/4/5 cable in 10 Mbps operation. To reli-
ably operate your network at 100 or 1000Mbps, you must use an
Note
Unshielded Twisted-Pair (UTP) Category 5/5e cable, or better Data
Grade cabling. While a Category 3 or 4 cables may initially seem
to work, it will soon cause data loss
