BRAND NEW WITH THE FULL HP LIMITED LIFETIME WARRANTY!!!
The HP 2910-24G al Switch is a managed switch with 24 10/100/1000 ports (20 copper ports and 4 dual personality Gig ports ) and 4 optional 10G ports ( CX4/SFP+)
The HP 2910 al Switch Series consists of four switches: the HP 2910-24G al and 2910-24G-PoE+ al Switches with 24 10/100/1000 ports, and the HP 2910-48G al and 2910-48G-PoE+ al Switches with 48 10/100/1000 ports. Each switch has four dual-personality ports for 10/100/1000 or mini-GBIC connectivity. In addition, the 2910 al Switch Series supports up to four optional 10 Gigabit Ethernet (CX4 and/or SFP+) ports, thereby offering the most flexible and easy-to-deploy uplinks in its class. Together with static and RIP IPv4 routing, robust security and management, enterprise-class features, free lifetime warranty, and free software updates, the 2910 series is a cost-effective, scalable solution for customers who are building high-performance networks. These switches can be deployed at enterprise edge and remote branch offices, converged networks, and data center top of rack.
Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues. Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers. Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ. Rate limiting: per-port ingress enforced maximums.
10 Gbps Ethernet connectivity: up to four optional and flexible 10-Gigabit ports (CX4 and/or SFP+), with optional interconnect kit for short-distance connectivity. IPv6: IPv6 host: allows the switches to be managed and deployed at the edge of IPv6 networks . Dual stack (IPv4/IPv6): provides transition mechanism from IPv4 to IPv6; supports connectivity for both protocols. MLD snooping: forwards IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from flooding the network. IEEE 802.3af Power over Ethernet (PoE): 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. IEEE 802.3at Power Over Ethernet Plus: provides up to 30 W per port to IEEE 802.3 for PoE/PoE+ powered devices such as video IP phones, IEEE 802.11n wireless access points, and advanced pan/zoom/tilt security cameras. Pre-standard PoE support: detects and provides power to pre-standard PoE devices; see list of supported devices in the product FAQ at www.hp.com/networking/support.
High-performance architecture: 128 Gbps switching fabric with up to 95 Mpps (24-port switches) and 176 Gbps switching fabric with up to 131 Mpps (48-port switches). Selectable queue configurations: allow you to increase performance by selecting the number of queues and associated memory buffering that best meet the requirements of your network applications.
IEEE 802.1s Multiple Spanning Tree: provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for IEEE 802.1d and IEEE 802.1w. IEEE 802.3ad Link Aggregation Protocol (LACP) and HP port trunking: support up to 24 trunks, each with up to 8 links (ports) per trunk. Optional redundant power supply: supplies backup power in case of power failure (note: HP E620 Redundant/External Power Supplyprovides only RPS functionality).
RMON, XRMON, and sFlow: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events. Uni-Directional Link Detection (UDLD): monitors a link between two switches and blocks the ports on both ends of the link if the link goes down at any point between the two devices. Command authorization: leverages RADIUS to link a custom list of CLI commands to an individual network administrator's login; also provides an audit trail. Dual flash images: provides independent primary and secondary operating system files for backup while upgrading. Multiple configuration files: allow multiple configuration files to be stored to a flash image.
VLAN support and tagging: supports IEEE 802.1Q (4,094 VLAN IDs) and 256 VLANs simultaneously. GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs. Jumbo packet support: supports up to 9220-byte frame size to improve the performance of large data transfers. IEEE 802.1v protocol VLANs: isolate select non-IPv4 protocols automatically into their own VLANs.
