Product overview

The HP 2920 Switch Series consists of ve switches: the 2920-24G and 2920-24G-PoE+

switches with 24 10/100/1000 ports and the 2920-48G, 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

exible and easy-to-deploy uplinks and stacking.

Together with static and routing-information-protocol (RIP) routing, robust security and

management, enterprise-class features, free lifetime warranty, and free software updates,

the 2920 Switch Series is a comprehensive, cost-eective, and scalable solution for building

high-performance networks. These switches can be deployed at the enterprise edge, in remote

branch oces, and in converged networks.

A summary of the highlights of the 2920 Switch Series:

• High-performance Gigabit Ethernet access switch

• Four optional 10GbE (SFP+ and/or 10GBASE-T) ports

• Stacking capability with a total of four switches

• L2 and L3 plus static and RIP routing, PoE, and PoE+ support

• Lifetime warranty, sFlow, ACLs, OpenFlow, and rate limiting
