OVERVIEW:
Dell™ PowerConnect™ 6200 offers advanced switching capabilities including Power Over Ethernet (PoE), high-density, high-performance stacking and 10 Gigabit Ethernet capabilities scalable from the small business to the Enterprise Edge.
FEATURES:
• With 24 or 48 built-in copper Gigabit Ethernet ports in a 1U form factor, as well as a 24 port Fiber GbE version for backbone or long-haul connectivity, the PowerConnect 6200 series gives users the flexibility to maximize server and workstation connectivity in a 1U form factor. The switches also offer support up to four 10 Gigabit Ethernet uplinks for connectivity directly to 10GbE servers, enterprise backbones and distributed campus wiring closets (IDF and MDF).
• High-performance stacking with 10GbE: The PowerConnect 6200 series supports highperformance resilient stacking for up to twelve systems and almost 2 Terabits of capacity in a single stack (each switch supports up to 184 Gbps in switch capacity). The unique modular design allows you to upgrade to advanced stacking or 10 Gigabit Ethernet only when you need it. Plus the 6200 series offers further flexibility with optional modules that allow for either 10 Gigabit copper interfaces, or both. The optional stacking interfaces allow for high availability stacking with sub-100ms failover times, even in the event of a master unit failure.
• Advanced switching features with robust security: The PowerConnect 6200 series supports advanced Layer 3 routing and multicast protocols to help reduce congestion and manage traffic in the network. The PowerConnect 6200 series supports frequently used LAN routing protocols such as RIPv1/v2, OSPFv2/v3, VRRP, IGMP v1/v2/v3, DVMRP, PIM and LLDP-MED. The PowerConnect 6200 offers flexibility in Quality of Service (QoS) by giving network administrators the ability to prioritize time-critical Layer 2 or Layer 3 network traffic.
Support for L2-L4 Access Control Lists (ACLs) on the switch allows the user to perform deep packet inspection. 802.1x port authentication offers both single and multiple host access. Further security is provided through Denial of Service (DoS) Attack Prevention, whereby the switch can protect against common network attacks. PowerConnect 6200 switches are IPv6 ready.
• Power Over Ethernet (PoE) support: The PowerConnect 6200 series PoE switches offer PoE-per-port support for power-dependent network applications including WLAN Access Points (WAPs), Voice over IP (VoIP) handsets, video conferencing and badge reading. The 6224P and 6248P switches can provide up to 15.4 watts of power for networkattached devices.

HP J9028B ProCurve 1800-24G Gigabit Switch

OVERVIEW:
The HP 2810 Switch Series consists of two switches: the 24-port HP 2810-24G Switch with 20 10/100/1000 ports, and the 48-port HP 2810-48G Switch with 44 10/100/1000 ports. Each switch also has four dual-personality ports for RJ-45 10/100/1000 or mini-GBIC fiber Gigabit connectivity. Ideal for high-performance and secure 10/100/1000 connectivity, the 2810 switch series offers access security and advanced prioritization and traffic-monitoring capabilities.
