- Link down power saving - Intelligent scale power based on cable length   Cost-optimized, Configure-free Gigabit PoE+ Switch for System Integrators PLANET GSW-2620HP, an ideal Gigabit PoE Switch, provides a cost-effective advantage to local area networks of SMBs. Offering Layer 2 data packet switching and stable operation, this model also complies with IEEE 802.3at Power over Ethernet Plus (PoE+) at an affordable price. The GSW-2620HP is equipped with 24 10/100/1000BASE-T Gigabit Ethernet ports and 2 1000BASE-X SFP interfaces with inner power system. Its 24 Gigabit Ethernet ports are integrated with an 802.3at PoE+ injector function. It offers a rack-mountable, safe and reliable power solution for SMBs deploying Power over Ethernet networks.    IEEE 802.3at/af Compliant Power Source Switch The PoE in-line power following the IEEE 802.3at/af standard makes the GSW-2620HP able to deliver Gigabit speed data and up to 30 watts of power per port to 24 PoE compliant powered devices (PDs) with a combined power output budget of up to 220 watts. The GSW-2620HP provides more flexibility in power requirement for all kinds of PDs with affordable installation costs.    Energy-saving Design The GSW-2620HP uses new engine that incorporates two advanced Green Networking technologies:

• Idle Mode Link Down power saving
• Intelligent Scale Power based on cable length

  The Idle Mode Link Down power saving of the GSW-2620HP complies with IEEE 802.3az Energy Efficient Ethernet (EEE) standard to automatically lower power for a given port when it is not linked. The Intelligent Scale Power technology actively determines the appropriate power level based on the cable length. When connecting to the GSW-2620HP with Ethernet cable shorter than 20m, a device can obtain maximum power saving because the GSW-2620HP would automatically detect the Ethernet cable length and reduce power usage. The connected device can substantially reduce the overall power consumption, which makes a significant contribution to energy saving.    Easy Installation and Cable Connection Providing data transfer and high PoE in one unit, the GSW-2620HP is able to reduce the need of extended cables and electrical outlets on the wall, ceiling or any unreachable place. It helps to lower the installation costs and simplify the installation effort. All RJ45 copper interfaces of the GSW-2620HP support 10/100/1000Mbps auto-negotiation for optimal speed detection through RJ45 Category 6, 5 or 5e cables. It also supports standard auto-MDI/MDI-X that can detect the type of connection to any Ethernet device without requiring special straight-through or crossover cables.   Flexible Extension Solution The two mini-GBIC slots built in the GSW-2620HP are compatible with the 1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber 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 fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.
