3COM SuperStack 3 Switch 4400 PWR :

The SuperStack 3 Switch 4400 PWR combines Power over Ethernet technology (IEEE-P802.3af) with the advanced features, simplicity, and style of the SuperStack 3 Switch 4400 family. The compact stackable 1-RU design provides power and data over a single cable to any compliant device, including 3Com NBX phones, wireless LAN access points, and Network Jack products. Power over Ethernet eliminates additional electrical cabling costs and greatly reduces total installation time and expense, helping to lower the total cost of ownership, especially when paired with networked telephony solutions. The switch supports all SuperStack 3 Switch 4400 enhanced capabilities, such as traffic classification and prioritization, traffic filtering, and IEEE 802.1X network login for user-based security. The Switch 4400 PWR can stack with other enhanced SuperStack 3 Switch 4400 devices to form a resilient switch stack of up to 192 10/100 ports. This allows distribution of high-speed connections across the stack (up to 4Gbps) for resilient, high capacity connections to the network core, including those running with 3Com XRN technology. Use any of the SuperStack 3 Switch 4400 modules for Gigabit uplinks and stacking.
