HP 1910 switches are advanced smart managed fixed-configuration Gigabit and Fast Ethernet switches designed for small businesses in an easy-to-administer solution. The series has 8 gigabit models and 5 Fast Ethernet models. The gigabit models are : 8-, 16-, 24-, and 48-port 10/100/1000 non-PoE models; and two 8-port and two 24-port 10/100/1000 PoE models. Gigabit models have additional true Gigabit SFP ports for fiber connectivity. The Fast Ethernet models are : 8-. 24- and 48- 10/100 non-PoE models and 8-, 24- 10/100 PoE+ models. The Fast Ethernet models come with additional 2 combo uplink ports . All HP 1910 models support rack mounting or desktop operation. Customizable features include basic layer 2 features like VLANs and link aggregation as well as advanced features such as Layer 3 static routing, IPv6, ACLs and Spanning Tree Protocols. HP 1910 switches come with a lifetime warranty covering the unit, fans, and power supplies. Simple Web management: allows for easy management of the switch- even by nontechnical users- through an intuitive Web GUI; http and secure http (https) is supported. Single IP management: enables management of up to four HP 1910 devices using a single Web interface; simplifies management of multiple devices. Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS. SNMPv1, v2c, and v3: facilitates management of the switch, as the device can be discovered and monitored from an SNMP management station. Complete session logging: provides detailed information for problem identification and resolution. Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic. Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue minimums. 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 four hardware queues for more effective throughput. IPv6: IPv6 host: enables switches to be managed and deployed at the IPv6 network's edge. IPv6 routing: supports IPv6 static routes. MLD snooping: forwards IPv6 multicast traffic to the appropriate interface, preventing traffic flooding. IPv6 ACL/QoS: supports ACL and QoS for IPv6 network traffic. Auto-MDI/MDIX: adjusts automatically for straight-through or crossover cables on all 10/100/1000 ports. IEEE 802.3X flow control: provides a flow throttling mechanism propagated through the network to prevent packet loss at a congested node. IEEE 802.3af Power over Ethernet (PoE) ready: provides up to 15.4 W per port to power standards-compliant IP phones, wireless LAN access points, Web cameras, and more (all PoE models). IEEE 802.3at Power over Ethernet (PoE+): provides up to 30 W per port which allows support of the latest PoE+-capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3af-compliant end device; eliminates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. (Note: applies to all PoE models, except the two 24G-PoE models which support a pre-standard implementation of PoE+). Advanced access control lists (ACLs): enables network traffic filtering and enhances network control using MAC- and IP-based ACLs; time-based ACLs allow for greater flexibility with managing network access. Secure Sockets Layer (SSL): encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch. IEEE 802.1X and RADIUS network logins: controls port-based access for authentication and accountability. Automatic VLAN assignment: assigns users automatically to the appropriate VLAN based on their identity, location and time of day. STP BPDU port protection: blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks. Half-/full-duplex auto-negotiating capability on every port: doubles the throughput of every port. Selectable queue configurations: allows for increased performance by selecting the number of queues and associated memory buffering that best meet the requirements of the network applications. IGMP snooping: improves network performance through multicast filtering, instead of flooding traffic to all ports. Fiber uplink: provides greater distance connectivity using Gigabit fiber uplinks. VLAN support and tagging: supports IEEE 802.1Q (4,094 VLAN IDs) and 256 VLANs simultaneously. Spanning Tree Protocol (STP): supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP). BPDU filtering: drops BPDU packets when STP is enabled globally but disabled on a specific port. Jumbo frame support: supports up to 10 kilobyte frame size to improve the performance oflarge data transfers. Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network. DHCP relay: simplifies management of DHCP addresses in networks with multiple subnets.
