HP E2520-8G-PoE Switch: Fanless small form factor managed layer 2 switch with 8 10/100/1000 PoE port, J9298AThe HP 2520 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 2520-8-PoE, 2520-24-PoE, 2520-8G-PoE, and 2520-24G-PoE Switches. 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. Selectable queue configuration: allows you to increase 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. 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. 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). RJ-45 serial console port: front of unit location provides easy access to the switch CLI. Switch on a chip: provides highly integrated, high-performance switch design with a non-blocking architecture. Jumbo packet support: supports up to 9216-byte frame size to improve performance of large data transfers (2520G switch). 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. IEEE 802.1s Multiple Spanning Tree Protocol (MSTP): provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for IEEE 802.1w (Rapid Reconfiguration of Spanning Tree Protocol) and IEEE 802.1d (Spanning Tree Protocol). VLAN support and tagging: supports the IEEE 802.1Q (4,094 VLAN IDs) and up to 256 port-based VLANs simultaneously. GARP VLAN Registration Protocol (GVRP): allows automatic learning and dynamic assignment of VLANs. Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network. ddress table size 8000 entries Form Factor 1U height Input Frequency 50/60 Hz Input Operating Current 1.5 A Input Voltage 100-240 VAC Management features HP PCM+; HP PCM; command-line interface; Web browser; configuration menu; out-of-band management (serial RS-232C); IEEE 802.3 Ethernet MIB; Repeater MIB; Ethernet Interface MIB Manufacturer Warranty Lifetime, advance replacement, next business day Ports 8 RJ-45 autosensing 10/100/1000 PoE ports(IEEE 802.3 Type 10BASE-T, IEEE 802.3u Type 100BASE-TX, IEEE 802.3ab Type 1000BASE-T, IEEE 802.3af PoE), Media Type: Auto-MDIX, Duplex: 10BASE-T/100BASE-TX: half or full; 1000BASE-T: full only; 2 dual-personality ports, each port can be used as either an RJ-45 10/100/1000 port (IEEE 802.3 Type 10Base-T; IEEE 802.3u Type 100Base-TX; IEEE 802.3ab 1000Base-T Gigabit Ethernet) or as a SFP slot (for use with SFP transceivers); 1 RJ-45 serial console port Power consumption 86.2 W (maximum) Power consumption, standby 9.3 W Power features Use only the external power adapter module (5070-6082, PA1 AC adapter) supplied with this product Product dimensions (W x D x H) 6.28 x 10 x 1.75 in.
