Planet GSD-504UP 2-Port 10/100/1000T 802.3bt PoE + 2-Port 10/100/1000T 802.3at PoE + 1-Port Gigabit Desktop Switch (External 120 Watts)
GSD-504UP is the smallest unmanaged Gigabit PoE switch equipped with two 802.3bt PoE++ ports, two 802.3at PoE+ ports, and one uplink port. With a total PoE power budget of 120 watts and non-blocking data switching performance, the GSD-504UP can fulfill the demand for sufficient PoE power for different applications.
Plug and Play High Power Sourcing Solution
Complying with the IEEE 802.3bt Power over Ethernet Plus Plus technology, the GSD-504UP provides up to 90 watts of PoE output power, tripling that of the earlier 802.3at plus. With the Legacy function enabled via the DIP switch, it can be backward compatible with 802.3af/at PoE standards to allow users to flexibly deploy standard and high-powered devices simultaneously with no need for software configuration. With data and Power over Ethernet from one unit, the GSD-504UP can reduce cable deployment and eliminate the need for dedicated electrical outlets on the wall, ceiling, or any unreachable place.
Environment-friendly, Fanless Design for Silent Operation
The GSD-504UP comes with a desktop-sized, compact metal housing, making the placement of the unit convenient. It features a ventilated construction in which a cooling fan is not necessary, thereby making its operation noiseless. Moreover, the GSD-504UP is able to operate reliably and stably in any environment without affecting its performance. The deployment of PoE PDs with constant power feeding can be easily and quickly done.
Robust Protection
The GSD-504UP protects against the ESD 6KV surge to improve product stability and also protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate.
Ideal Solution for SOHO to Have IP Surveillance Secure
As IP surveillance is in great demand, the GSD-504UP PoE++ Switch is also best used as a Surveillance Switch to supply PoE power to PoE IP cameras without requiring an extra cabling or electrical outlet, making the deployment of cameras quick and convenient. The GSD-504UP supports two 802.3bt PoE ++ ports and two 802.3at PoE+ ports along with four 10/100/1000BASE-T ports featuring up to 90 or 30 watts, and one extra Gigabit Ethernet TP interface supporting high-speed transmission of surveillance images and videos.
Perfectly integrated Solution for PoE IP Camera and NVR System
The GSD-504UP provides four 802.3at/bt PoE ports for catering to small-scale home and SOHO IP surveillance networks at a lower total cost. The GSD-504UP comes with a high-performance switch architecture and a 120-watt PoE power budget. The recorded video files from the 4 PoE IP cameras powered by the GSD-504UP are saved to the 4-channel NVR system.
IP Office Department/Workgroup PoE Switch
To further expand the office premises, the additional telephones required could be installed at less cost via the PoE IP telephony system, better than the traditional circuit wiring telephony system. The GSD-504UP PoE++ Switch helps enterprises to create an integrated data, voice, and powered network. The IEEE 802.3af/at compliant IP phones can be installed without the need for an additional power cable because the power can be provided via the standard Ethernet cable from the connected GSD-504UP. With the GSD-504UP, IP telephony deployment becomes more reliable and cost-effective, thus helping enterprises save tremendous costs when upgrading from the traditional telephony system to IP telephony communications infrastructure.
