Product overview

The HP 1420 Switch Series consists of unmanaged Gigabit Ethernet switches, for small business and others looking for plug-and- play basic Layer 2 connectivity for their network, including low-cost PoE+ and 10-Gigabit uplink models.

The 1420 Switch Series includes four Gigabit switches. All have 10/100/1000 ports for affordable Gigabit connections using copper Cat 5e cabling. There is a 16-port RJ45-only model. There is a 24-port model with two SFP Gigabit ports, ideal where long distances require fiber-based connections. Another 24-port model supports IEEE 802.3at PoE+ on 12 of its ports, able to forward up to 30W power on these ports to power Access Points, IP phones, IP cameras and other PoE-enabled devices. For cost-effective high-speed fiber-based server connections, there is a 24-port 10/100/1000 switch with two SFP+ 10-Gigabit ports.

HP 1420 switches have quality of service (QoS) support and IEEE 802.3x flow control features that improve network efficiency.

Simplified plug-and-play convenience is supported by features such as auto-MDIX and autospeed negotiation. HP has innovated and combined the latest advances in silicon technology to bring you some of the most power-efficient switches. All models support the Energy Efficient Ethernet IEEE 802.3az standard, as well as auto power-down mode on idle ports, and power saving on

Features and benefits

Ease of use

·         Unmanaged

provides plug-and-play simplicity

·         Auto-speed negotiation

selects individual port speed automatically, depending on client capabilities; removing the need for manual intervention enables simple plug-and-play operation

·         Comprehensive LED display with per-port indicators

provides an at-a-glance view of the status, activity, speed, and full-duplex operation of the switches

·         Flow control

helps ensure reliable communications during full-duplex operation

·         HP/IEEE Auto-MDIX

automatically adjusts for straight-through or crossover cables on all RJ-45 ports

Connectivity

·         Gigabti Ethernet 10/100/1000 Connectivity -- high speed Ethernet connections over highly affordable copper Category 5 cabling.

·         NEW 10-Gigabit fiber connectivity

Future-proof 10-Gigabit technology allows high-speed fiber connection to servers or other switches, with connection flexibility using optional SFP+ or SFP transceivers.

·         NEW 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; reduces the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments (for PoE model)

Performance

·         Energy-efficient Ethernet support

supports new IEEE 802.3az standard; and allows lower power consumption, when operated with IEEE-compliant client devices in 100 Mb/s mode only

·         Half-/full-duplex auto-negotiating capability on every port doubles the throughput of every port

·         Jumbo frame support

allows frames up to 9,216 bytes to be switched through the network

Flexibility

·         Fanless design

enables quiet operation for deployment in open spaces

·         NEW Internal power supply

delivers operational convenience and an environment suitable for business operations

Quality of Service (QoS)

·         IEEE 802.1p prioritization

delivers data to devices, based on the priority and type of traffic

·         DiffServ Code Point (DSCP) support

allows real-time traffic prioritization, based on L3 TOS/DSCP parameters
