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. 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 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. Connectivity • Auto-MDIX: automatically adjusts for straight-through or crossover cables on all ports Performance • Switch on a chip: provides highly integrated, high-performance switch design with a non-blocking architecture Resiliency and high availability • Port trunking and link aggregation: Trunking: supports up to eight links per trunk to increase bandwidth and create redundant connections. IEEE 802.3ad Link Aggregation Protocol (LACP): eases configuration of trunks through automatic configuration. Layer 2 switching • VLAN support and tagging: supports the IEEE 802.1Q (4,094 VLAN IDs) and up to 256 port-based VLANs simultaneously Security • Manager and operator privilege levels: enables read-only (operator) and read-write (manager) access on management interfaces Data transmission: - Jumbo frames support: Yes - MAC address table: 8000 - Maximum data transfer rate: 1 - Number of queues: 4 - Packet buffer memory: 0.5 - Supported data transfer rates: 10/100 Mbps - Switching capacity: 48 - Throughput: 35.7 Design: - Electromagnetic compatibility: FCC, VCCI, EN/CISPR, ICES, AS/NZS, IEC/EN - Safety: cUL, UL, CE, EN, AS/NZS Management features: - MIB support: MIB II, Bridge MIB, RMONv2 MIB, SMON MIB, Ethernet-Like-MIB, MAU MIB, Entity MIB - 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 - Link aggregation: Yes - Networking standards: IEEE 802.1D/IEEE 802.1p/IEEE 802.1Q/IEEE 802.1s/IEEE 802.1w/IEEE 802.3/IEEE 802.3ab/IEEE 802.3ad/IEEE 802.3af/IEEE 802.3u/IEEE 802.3x - Number of VLANs: 4096 - Port mirroring: Yes - Spanning tree protocol: Yes Operational conditions: - Heat dissipation: 233 - Operating altitude: 0 - 3000 - Operating relative humidity (H-H): 15 - 95 - Operating temperature (T-T): 0 - 50 - Operating temperature (T-T): 32 - 122 - Storage relative humidity (H-H): 15 - 95 - Storage temperature (T-T): -40 - 70 Other features: - Acoustic pressure emissions: 37.7 - Connectivity technology: Wired - Dimensions (W x D x H) (imperial): 17.44 x 9.69 x 1.75 - Dimensions (WxDxH): 246.1 x 443 x 44.5 - Input frequency: 50/60 - Input voltage: 100 - 240 - Latency: 5.3µs/2.7µs - Mounting: EIA - Networking features: Gigabit Ethernet - Weight (imperial): 7.21 - Wi-Fi: No Performance: - Built-in processor: Yes - Flash memory: 32 - Internal memory: 128 - Memory type: DDR2-SDRAM - Noise level: 28.3 - Processor frequency: 266 - Processor model: PowerPC MPC8313 Ports & interfaces: - Basic switching RJ-45 Ethernet ports quantity: 20 - Combo SFP ports quantity: 4 - Console port: RS-232 - SFP/SFP+ slots quantity: 4 Power: - Input current: 3.3 - Power consumption (typical): 260.4 Power over Ethernet (PoE): - Power over Ethernet (PoE): Yes Protocols: - Data link protocols: LLDP - Management protocols: IGMPv3, SNMPv1/v2c/v3 - Supported network protocols: IPv6, UDP, TFTP, ICMP, TCP, ARP, Telnet, BOOTP, SNTPv4 Security: - Access Control List (ACL): Yes - DHCP features: DHCP client/DHCP server - IGMP snooping: Yes - MAC address filtering: Yes - Security algorithms: 802.1x RADIUS/SSH/SSL/TLS - SSH/SSL support: Yes - Static port security: Yes Vendor information: - Brand Name: Hewlett Packard Enterprise - Warranty: 1 - Product.Details.Specifications.Level1: Network - Product.Details.Specifications.Level2: Wired Network - Product.Details.Specifications.Level3: Network Switches - Product.Details.Specifications.Level4: Network Switches
