E2520-8-PoE The HP E2520 Switch Series is ideally suited for small and medium businesses looking to deploy voice, video, or wireless solutions that require Power over Ethernet (PoE) connectivity. The series consists of four switches: the HP E2520-8-PoE, the HP E2520-24-PoE, the HP E2520-8G-PoE, and the HP E2520-24G-PoE Switch. The four models offer a choice of either Fast Ethernet or Gigabit Ethernet connectivity. All models also include support for dual-personality Gigabit Ethernet ports that can be used for either copper or fiber connectivity. All products are fully managed via SNMP, command-line interface (CLI), and graphical user interface (GUI) and offer a Layer 2 feature set. In addition, the products provide deployment flexibility with compact, quiet, and energy-efficient designs. Key features: - Fully managed Layer 2 switch in 8 or 24 ports; - Choice of Fast Ethernet or Gigabit PoE models; - Power over Ethernet for voice, video, and wireless; - Energy-efficient design and quiet operation; - Rack-mountable and compact form factors. Quality of Service (QoS) Selectable queue configuration: increases performance and/or traffic reliability by selecting the number of queues that best meet the requirements of your network applications; switch will map 8 priorities to either 2 or 4 queues. Simplified QoS configuration: - Port-based: prioritize traffic by specifying a port and priority level; - VLAN based: prioritize traffic by specifying a VLAN and priority level. - IEEE 802.1p traffic prioritization: honors and sets IEEE 802.1p priority in the VLAN tag. Type of service: - IP Precedence: honors IP Precedence bits and allows mapping to a priority queue; - Differentiated Services Code Point values: honors Differentiated Services Code Point (DSCP) bits and allows mapping to a priority queue. Flow control: helps ensure reliable communications during full-duplex operation. Management Choice of management interfaces: - Web graphical user interface (GUI): easy-to-use graphical interface allows configuration of the switch from any Web browser; - Command-line interface (CLI): robust command-line interface provides advanced configuration and diagnostics; - Simple Network Management Protocol (SNMPv2c/SNMPv3): allows switch to be managed with a variety of third-party network management applications. Integration with HP PCM: enables discovery, mapping, logging, and configuration via HP PCM, which is available as a free download from the Web. Virtual stacking: single IP address manages up to 16 switches. Port mirroring: allows traffic to be mirrored on any port or a network analyzer to assist with diagnostics or detecting network attacks. Multiple configuration files: configuration file management tools allow up to three configuration files to be managed and stored on the switch. Dual flash images: provide independent primary and secondary operating system files for backup while upgrading. Network tools: command-line interface includes telnet client, ping, traceroute, and Layer 2 link test tools for diagnostics. IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol for easy mapping by network management applications. Command authorization: leverages RADIUS to link a custom list of CLI commands to individual network administrator's login; also provides an audit trail. Logging: local and remote logging of events via SNMP (v2c and v3) and syslog. IPv6 host: allows switches to be managed using IPv6 protocols. RMON: provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events. Find-Fix-Inform: finds and fixes common network problems automatically, then informs administrator. Front-panel LEDs: - Locator LED: allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches; - Per-port LEDs: provides an at-a-glance view of status, activity, speed, and full-duplex operation; - Power and fault LEDs: display any issues. Connectivity - Auto-MDIX: automatically adjusts for straight-through or crossover cables on all ports; - Small Form-Factor Pluggable (SFP) slots: dual-personality ports allow for either copper or fiber connectivity such as Gigabit-SX, -LX, -LH, and -BX or 100-FX and -BX; - IEEE 802.3af Power over Ethernet: provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras (see product specifications for total PoE power available); supports some prestandard PoE devices (see product FAQs for more details); Data transmission: - Jumbo frames support: Yes - MAC address table: 8000 - Maximum data transfer rate: 1 - Packet buffer memory: 0.384 - Supported data transfer rates: 10/100 Mbps - Switching capacity: 5.6 - Throughput: 4.1 Design: - Certification: FCC, VCCI - Product colour: Silver - Safety: cUL, CE, IEC - Stackable: No Management features: - MIB support: Y - Quality of Service (QoS) support: Yes - Switch layer: L2 - Switch type: Managed - System event log: Yes - Web-based management: Yes Multicast features: - Multicast support: Yes Network: - 10G support: No - Auto MDI/MDI-X: Yes - Broadcast storm control: Yes - Copper ethernet cabling technology: 1000BASE-T/1000BASE-TX/100BASE-TX/10BASE-T - Flow control support: Yes - Full duplex: Yes - Networking standards: IEEE 802.1p/IEEE 802.1Q/IEEE 802.1s/IEEE 802.3/IEEE 802.3ab/IEEE 802.3ad/IEEE 802.3af/IEEE 802.3u/IEEE 802.3x - Number of VLANs: 4094 - Port mirroring: Yes - Rate limiting: Yes - Spanning tree protocol: Yes Operational conditions: - Operating relative humidity (H-H): 15 - 95 - Operating temperature (T-T): 0 - 45 - Operating temperature (T-T): 32 - 113 - Storage relative humidity (H-H): 15 - 95 - Storage temperature (T-T): -40 - 70 Other features: - Connectivity LEDs: Y - Connectivity technology: Wired - Dimensions (W x D x H) (imperial): 10 x 6.28 x 1.75 - Dimensions (WxDxH): 254 x 159.5 x 44.5 - Input frequency: 50/60 - Latency: 1.9 µs/1.5 µs - Networking features: Gigabit Ethernet - Weight (imperial): 3.62 Performance: - Built-in processor: Yes - Flash memory: 32 - Internal memory: 128 - Memory type: DDR2-SDRAM - Processor frequency: 266 - Processor model: PowerPC MPC8313 Ports & interfaces: - Basic switching RJ-45 Ethernet ports quantity: 8 - Combo SFP ports quantity: 2 - SFP/SFP+ slots quantity: 2 Power: - Input current: 1.5 - Input voltage: 100 - 240 - Power consumption (typical): 85.5 Power over Ethernet (PoE): - Power over Ethernet (PoE): Yes Protocols: - Management protocols: SNMP v1, v2c, v3 Security: - DHCP features: DHCP client/DHCP server - IGMP snooping: Yes - MAC address filtering: Yes - Security algorithms: 802.1x RADIUS/HTTPS/SSH - SSH/SSL support: Yes - Static port security: Yes Vendor information: - Brand Name: HP - Warranty: 1 - Product.Details.Specifications.Level1: Surveillance & Security - Product.Details.Specifications.Level2: Infrastructure - Product.Details.Specifications.Level3: Wired Network - Product.Details.Specifications.Level4: Network Switches
