Introducing the HP 2920 Switches

The HP 2920 switches are multi-port switches that can be used to build high-

performance switched networks. These switches are store-and-forward

devices offering low latency for high-speed networking. The HP 2920 switches

also support a field-replaceable power supply, Power over Ethernet (PoE/

PoE+) technologies, and full network management capabilities.

In addition, the HP 2920 switches support the HP 2920 Stacking Technology

feature for stacking the switches. When 2920 Stacking Modules (J9733A) are

installed in the switches, any combination of up to four HP 2920 switches can

be stacked together via high-speed backplane cables to form a single extended

virtual switch. See “Stacking Information and Topologies” on page 2-25, and

the Advanced Traffic Management Guide for more stacking information.

These switches are described in this manual:

This chapter describes these switches with the following information:
