D-Link’s DES-3526 is a high-performance, managed, stackable Layer 2 switch that provides an ideal solution for workgroups and departments. The D-Link Single IP Management (SIM) allows to cluster up a virtual stack of up to 32 DES-3526 and/or DES-3550 dispersed switches with fewer distance limitation through a single IP address.

The clustering environment spans buildings, making it perfect for business that requires multiple building deployment. The (24) 10/100Mbps Fast Ethernet ports allow desktops to access network resources through flexible 2 Gig uplinks. The entire virtual stack can be managed via a single IP address for simplified network administration.

High-Performance, High Availability L2 Switching
Utilizing an 8.8Gbps switch capacity and support for 8,000 MAC addresses, the DES-3526 Stackable Layer 2 Switch is a wire-speed, high performance switch ideal for workgroups or departments. The DES-3526 supports port trunking with up to 6 trunk groups with 2 to 8 ports in each group per stack. Port trunking enables business users to increase availability and aggregated bandwidth between servers and/or other switches, optimizing the transport of business critical data. The DES-3526 can utilize either the 10/100Mbps or the 1 Gbps port to interconnect up to 32 units within a virtual stack.

Investment Protection
By widely supporting IEEE approved specifications, the DES-3526 Stackable Layer 2 Switch leverages your existing investment in a multi-vendor environment, while maximizing compatibility of mission critical features such as, Spanning Tree (802.1d), QoS (802.1p/DiffServ/TCP &UDP port number), VLANs (802.1Q), and network management (SNMP/RMON/BOOTP/Telnet/Web).

The DES-3526’s robust support of standards-based network management protocols (SNMP/RMON/BOOTP/ Telnet/Web/TFTP) and port mirroring enables the DES-3526 to be easily integrated into many third-party network management packages.

Advanced Enterprise Features
The DES-3526 Stackable Layer 2 Switch brings advanced enterprise functions to a more affordable level while supporting advanced features: D-Link Single IP Mangement, Dual Images, L2/L3/L4 (QoS), 802.1x (Port-based Authentication), 802.1x (MAC-based Authentication)IGMP snooping, 802.1w (Rapid Spanning Tree), 802.1s (Multiple Spanning Tree group), 802.3ad (Link Aggregation), and 802.1q (VLANs). L2/L3/L4 (ACLs) can be configured based on: Protocol type, 802.1p, DSCP, MAC Address, IP Address, and/or TCP/UPD Port Number. These features facilitate the deployment of enterprise applications such as: VOIP, streaming media, and multicast content delivery (IP video conferencing and software deployment).
