Product Information

Full Description

Details

The HP 2920 Switch Series consists of five switches: the HP 2920-24G and 2920-24G-PoE+ Switches with 24 10/100/1000 ports, and the HP 2920-48G and 2920-48G-PoE+ and 2920-48G 740W PoE+ Switches with 48 10/100/1000 ports. Each switch has four dual-personality ports for 10/100/1000 or SFP connectivity. In addition, the 2920 switch series supports up to four optional 10 Gigabit Ethernet (SFP+ and/or 10GBASE-T) ports, as well as a two-port stacking module. These options provide you with flexible and easy-to-deploy uplinks and stacking. Together with static and RIP routing, robust security and management, enterprise-class features, free lifetime warranty, and free software updates, the HP 2920 Switch Series is a cost-effective, scalable solution for customers who are building high-performance networks. These switches can be deployed at the enterprise edge, in remote branch offices, and in converged networks.

Connectivity

IEEE 802.3at Power over Ethernet (PoE+): provides up to 30 W per port that 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. Two-port stacking module with up to 40 Gb/s per port: optional two-port stacking module allows stacking of up to four switch units into a single virtual device. 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. Flexible 10 Gb/s Ethernet connectivity: up to four optional 10-Gigabit ports (SFP+ and/or 10GBASE-T). Auto-MDIX: provides automatic adjustments for straight-through or crossover cables on all 10/100 and 10/100/1000 ports.

Performance

Energy-efficient design: High-efficiency power supplies: 80 PLUS Silver Certified power supply increases power savings. Energy-efficient Ethernet (EEE) support: reduces power consumption in accordance with IEEE 802.3az. HP ProVision ASIC architecture: is designed with the latest HP ProVision ASIC, providing very low latency, increased packet buffering, and adaptive power consumption. 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.

Software-defined networking

OpenFlow: is a key technology that enables software-defined networking by allowing the separation of data (packet forwarding) and control (routing decision) paths

Quality of Service (QoS)

Large buffers: provide graceful congestion management. Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue minimums. 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. Layer 4 prioritisation: enables prioritisation based on TCP/UDP port numbers. Traffic prioritisation (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues.

Convergence

IEEE 802.1AB Link Layer Discovery Protocol (LLDP): facilitates easy mapping using network management applications with LLDP automated device discovery protocol. LLDP-MED (Media Endpoint Discovery): defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones. IP multicast snooping and data-driven IGMP: automatically prevent flooding of IP multicast traffic. PoE and PoE+ allocations: support multiple methods (automatic, IEEE 802.3at dynamic, LLDP-MED fine grain, IEEE 802.3af device class, or user specified) to allocate and manage PoE/PoE+ power for more efficient energy savings.

Management

SNMPv1, v2, and v3: provides complete support of SNMP; provide full support of industry-standard Management Information Base (MIB) plus private extensions; SNMPv3 supports increased security using encryption. Out-of-band Ethernet management port: enables management over a separate physical management network, keeping management traffic segmented from network data traffic.

Resiliency and high availability

IEEE 802.3ad Link Aggregation Control Protocol (LACP) and HP port trunking: support up to 60 static, dynamic, or distributed trunks active across a stack, with each trunk having up to eight links (ports) per static trunk; support trunking across stack members. Ring and chain stacking topology: allows failure of a link or switch in the ring of stacked switches, while the remaining connected switches continue operation. 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.

Out of stock

:(

Well, this is disappointing - this product has sold out. Fear not though, more may be on order or we may be able to source it for you.

Are we out on price?

We check our prices daily against a wide range of competitors to try to bring you the best deal. However, if you've spotted a better price offered by one of our competitors, please let us know and we'll do our very best to match it.

Price Match Challenge

Is the advertised price & availability genuine?

The IT sector is littered with companies who don't hold stock. Their websites advertise products that are sourced from third party suppliers. Pricing and availability data on such sites is typically retrieved from files or feeds which are often not refreshed regularly enough. The result? Cancelled orders, long lead times and disgruntled customers.

King of Servers is a major stockholder with full transparency into our stockholding and pricing. Our website is refreshed on a 15-minute cycle 24/7 so the pricing and availability you see online is both accurate and reliable.

We recommend you double check a cheaper price elsewhere is accurate and based on physical stock that can be shipped immediately before placing your order.

Do they really have the product in stock?

We show true stock counts on our website, not woolly messages like ‘in stock' or ‘available to order'. Stock levels are updated every 15 minutes 24/7 so you can see exactly how many units we have sat in our warehouse available for immediate despatch.

And speaking of shipping, did you know we offer same day deliveries? You can choose this or other timed services during checkout on our website or contact our sales team for a quote. Handy when you need the goods in a hurry!

Do they specify product condition?

Most web stores fail to specify the stock condition of the products they advertise for sale. It seems reasonable to assume that all products are brand new, unused units supplied in the sealed, original manufacturer packaging and protected by the full warranty but this isn't always the case.

A heavily discounted price can be a sign that the product in question may be a used or refurbished unit. Open/damaged box and ‘ex demo' units are also rife in the marketplace and warranty cover on such goods will be variable so it's wise to check what you're getting before committing to any purchase.

King of Servers displays the product condition on all our product pages. As well as detailing what the condition means, we specify the level of warranty condition allowing you to make an informed buying decision.

Ensure you compare like for like when shopping around for prices online.

Is the product covered by warranty?

All brand new products come with a full manufacturer warranty, right? Not always; it depends where the products were sourced from. You may have heard of the grey market or parallel imports? Manufacturers often stipulate the geographical regions in which their products are designated for sale. Unscrupulous suppliers seek to source goods from outside of these regions at cheaper costs which they pass on via cheaper prices. The downside is that the manufacturer might not honour the warranty in the event of a support call. Grey kit does not qualify for warranty support and if it fails, you could be significantly out of pocket.

All products offered for sale at King of Servers are sourced from legitimate channels and are covered by warranty. For added peace of mind, we can supply serial numbers up front which can be validated on the manufacturer's website to ensure warranty cover is in place prior to purchase.

Ask any potential supplier if they can supply serial numbers ahead of purchase. Any legitimate stockholder who has sourced the goods from the proper channels should be able and happy to do so.

Is the competitor trustworthy?

Look beyond the price and establish whether the company behind the product is a bona fide organisation that you can return to should you encounter issues down the line. This is particularly important if you've never heard of them before. It's relatively easy to set up a web shop nowadays which makes it difficult to differentiate between a one-man band operating out of a home office and a well-established, reputable bricks and mortar business. Sales T&Cs, returns policy and aftercare service are probably important areas for you to consider.
