Product Overview

The 3Com Switch 5500-EI 28-Port is a premium stackable 10/100 switch with Enhanced Image (EI) software for businesses running the most demanding network applications requiring the highest "five 9s" network uptime. 24-ports operate at 10/100 while four additional SFP-based ports operate at Gigabit speeds. All 3Com Switch 5500 products share the same operating system as our premium modular switches and routers, including the 3Com Switch 8800 and 7700. This permits you to manage an entire distributed switching and routing infrastructure from a single CLI or SNMP management platform such as 3Com Enterprise Management Suite or 3Com Network Director.
