Hewlett Packard Enterprise 1820-24G-PoE+ (185W). Switch type: Managed, Switch layer: L2. Basic switching RJ-45 Ethernet ports type: Gigabit Ethernet (10/100/1000), Basic switching RJ-45 Ethernet ports quantity: 24. Full duplex. MAC address table: 8000 entries, Switching capacity: 52 Gbit/s. Networking standards: IEEE 802.3, IEEE 802.3ab, IEEE 802.3u. Power connector: DC-in jack. Power over Ethernet (PoE). Rack mounting, Form factor: 1UThe HP 1820 Switch Series offers more choice and flexibility for smaller organizations that require ease of use and lower Total Cost of Ownership (TCO), while delivering better network performance. They are smart-managed, fixed configuration, Gigabit Ethernet Layer 2 switches in an easy-to-administer solution that have the latest energy-saving capabilities. These switches are plug-and-play out of the box, where network operation can be fine-tuned through features available from a simple Web browser-based GUI, when needed. Features Easy-to-Use, Simple to Deploy and Manage - The HP 1820 Switch Series features an intuitive Web management interface with an enhanced navigation pane for easy management of devices by non-technical users. The HP 1820 Switch Series is ideal for organizations that require simplicity. - The series gives you flexibility and choice with a complete portfolio. You get six rack-mountable models including three non-Power over Ethernet (PoE) models. Some models include SFP ports for fiber connectivity. - Customizable features include VLANs, Spanning Tree, Link aggregation trunking, and IGMP Snooping. All models include Rapid Spanning Tree Protocol (RSTP) and DSCP QoS policies. - These switches support flexible installation options, including mounting on walls, under tables or on desk tops. - Some models are of a fan-less design, making them quiet for office deployments. Energy Efficiency and Lower TCO - The HP 1820 Switch Series include the latest energy-savings capabilities, including Energy Efficient Ethernet (IEEE), idle-port power down and PoE Port Scheduler. - The 8-port Gigabit Ethernet model can be powered by an upstream PoE switch for environments where no line power is available. - All switches are covered by a Limited Lifetime Warranty 2.0 with limited 24x7 telephone support for the first three years. Quality of Service (QoS) - The HP 1820 Switch Series traffic prioritization provides time sensitive packets (like VoIP and video) with priority over other traffic based on DSCP or IEEE 802.1p classification. Packets are mapped to eight hardware queues for more effective throughput. - Broadcast control allows limiting of broadcast traffic rate, to reduce unwanted network broadcast traffic. - IEEE 802.11p/Q delivers data to devices based on the priority and type of traffic.
