24-Port Smart Switch with PoE
24 Ethernet Ports With PoE
The DES-1526 Smart Switch provides 24 10/100Mbps Ethernet ports supporting PoE for device connections. Complying with industry standard 802.3af Power over Ethernet (PoE), these ports provide power over the normally unused pairs of the Ethernet cables, which makes it very valuable for deployment of VoIP phones, remote surveillance cameras and wireless access points. In addition to PoE, the switch auto-senses Ethernet speeds and negotiates for full/half duplex transmission while supporting auto MDI/MDIX for easy, plug-and-play network connection.
2 Combo 1000BASE-T/SFP for Flexible Gigabit Connection
2 combo 1000BASE-T/SFP are provided for flexible copper or fiber Gigabit connection to the servers or network backbone. You can select to install optional transceivers in the SFP slots for short, medium or long-distance fiber backbone attachment. Use of the SFP will disable their corresponding built-in 1000BASE-T connections.
Designed for Business and Hot Spots
Suitable for installation at offices, factories, hospitals and schools, the DES-1526 can also be used for public Wi-Fi deployments requiring multiple access points, such as in hotels, airports, and marinas. For offices with VoIP, each phone must be individually powered, and a power failure in a building can leave phone service disrupted without an uninterruptible power supply (UPS) on each phone. For surveillance and wireless networks, cameras and access points typically need to be located in out-of-the-way locations such as on the ceilings or rooftops for maximum coverage, where wall AC outlets are inaccessible and providing power to these locations is difficult and expensive. By transmitting remote power through the standard network cabling, the DES-1526 provides a centralized power source for IP phones, cameras and wireless AP, eliminating the need for individual power sources for these devices.
Centralized Power Provision, Easy Deployment
In addition to eliminating the need for additional, separate wiring to power devices, the DES-1526 is also more costeffective than deploying an Ethernet switch and multiple single-port PoE injectors. Add a central UPS to the DES- 1526, and you can maximize uptime for all connected devices. This switch can simplify your installation while minimizing costs by eliminating UPS for each individual device. It has a rugged metal case, comes with an internal universal power supply, and can be mounted in a standard size equipment rack along with the centralized UPS.
Port Trunks for Aggregated Bandwidths
For connection to servers or the network backbone, the DES-1526 supports port trunking, which allows multiple Ethernet or copper Gigabit ports to be combined together to create a multi-link load-sharing aggregated bandwidth. You can also make use of the port trunk to eliminate bottlenecks between two cascaded switches.
VLANs for Enhanced Security & Performance
The DES-1526 supports Virtual LANs (VLAN) to let you implement security and improve bandwidth utilization. VLANs limit broadcast domains and confine intra-group traffic within their segments. To segment up the network, you can group devices, workstations and servers on the network into different VLANs, using 802.1Q standard VLAN tagging.
Quality of Service Support
The DES-1526 provides Layer 2 802.1p control for prioritized network packet transmission. Classification of network data priorities can be based on Priority Queues. This QoS support allows you to run bandwidth-intensive and delay-sensitive applications, and is of particular importance to IP phone and Internet server cameras attached to your network.
The DES-1526 supports port mirroring to assist network traffic monitoring. Your network administrator can use this function as a diagnostic tool or debugging feature, especially when fending off an attack. It enables you to keep close track of switch performance and alter it, if necessary. Port mirroring can be managed locally or remotely. Your administrator places a protocol analyzer on the port receiving the mirrored data to monitor each segment separately. The analyzer captures and evaluates the data without affecting the client on the original port.
The DES-1526 is designed as an affordable solution for business to implement security, QoS and power sourcing without having to go through complex SNMP network management. All functions can be configured for the switch from any network station via an Internet browser, dispensing you of the need to set up consoles and connect console cables.
